Big Hype Prospects: Moreno, Ortiz, Casas, Perez, Rafaela

By | at

This week on Big Hype Prospects, we catch up on some pre-holiday shopping.

Five BHPs In The News

Gabriel Moreno, 22, C, ARI (MLB)
(AAA) 267 PA, 3 HR, 7 SB, .315/.386/.420

Moreno headlined the Diamondbacks return in the Daulton Varsho trade. FanGraphs describes him as “the most athletic catcher to come along since J.T. Realmuto.” Last season, Moreno continued to put his contact skills on display. A brief 73 plate appearance trial in the Majors yielded a high batting average and tiny 11.0 percent strikeout rate. He generally produces modest exit velocities with a low angle of contact. In plain english, power isn’t a big part of his game, but he’ll be a valuable hitter all the same. He’ll need to make substantial adjustments to ever become a regular 20 homer threat.

There are questions about his ability to carry a full workload given that he’s never topped 350 plate appearances in a season. He’s considered an above average defender with sufficient athleticism to improve. With Carson Kelly still in-house, the Diamondbacks can consider platooning Moreno between catcher and designated hitter while working on his durability.

Luis Ortiz, 23, SP, PIT (MLB)
(AA) 114.1 IP, 9.92 K/9, 2.68 BB/9, 4.64 ERA

The lightbulb clicked for Ortiz partway through the 2022 campaign. His command improved as he became more aggressive with his domineering stuff leading to a successful 10 inning stint in Triple-A followed by 16 more frames in the Majors. Given his lack of Triple-A experience, it’s understandable why the Pirates have gone out of their way to delay Ortiz’s arrival via the signings of Vince Velasquez and Rich Hill. Ortiz has impressive Statcast measurables. Health permitting, he’s on pace to soon form a potent one-two punch with Roansy Contreras in the Pirates rotation.

Triston Casas, 22, 1B, BOS (MLB)
(AAA) 317 PA, 11 HR, .273/.382/.481

Virtually everybody in baseball is ready to see Casas sink or swim as the Red Sox first baseman of the present and future. The only barrier entering this offseason was a certain veteran. Removing Eric Hosmer from the roster ensures manager Alex Cora won’t have to juggle any difficult decisions. Casas had a mixed 95 plate appearance debut last season, showing power and discipline but posting a poor .197 batting average. In this case, his .208 BABIP appears especially fluky. If anything, his batting profile is that of a high-BABIP hitter. Some of his at bats felt like he was selling out for contact (my personal observation, not that of a scout), a common “mistake” among debut hitters. Look for him to further refine his approach and consistency in 2023.

Eury Perez, 19, SP, MIA (AA)
75 IP, 12.72 K/9, 3.00 BB/9, 4.08 ERA

On the shortlist with Andrew Painter for most exciting teenaged pitching prospect, Perez is one of the reasons the Marlins are shopping Major League starting pitchers. He’s on pace to arrive in the second half of 2023. Scouts laud his excellent fastball command and biting slider. He’s a skyscraper of a man whose very size ensures a unique look. Scouts believe his changeup can develop into a weapon as well. His curveball is seen as a less competitive offering that can play up based on the effectiveness of his other pitches.

It’s worth mentioning this is the organization that, a decade ago, jumped a 20-year-old Jose Fernandez straight from High-A to the Majors. Of course, none of those decision-makers remain on hand, making it highly unlikely we see a repeat with Perez.

Ceddanne Rafaela, 22, OF, BOS (AA)
(A+/AA) 522 PA, 21 HR, 28 SB, .299/.342/.539

The Red Sox are reportedly shopping their prospects for upgrades with Rafaela serving as the most-highly valued of the bunch. Rafaela wasn’t a consensus top prospect in the Red Sox system prior to last season. Now he’s widely considered their third-best farmhand behind Marcelo Mayer and Casas. He displayed a tantalizing mix of power and speed last season, though there are still worrisome signs with his offensive stats. He lacks discipline and carries a high swinging-strike rate. Hitters who thrive with the Javy Baez profile are few and far between.

Should his discipline and whiff issues become an impediment, Rafaela has super utility man potential. He’s presently being trained as a center fielder. He also played 12 games at shortstop last season and has prior experience at second and third base. He’s considered an above average outfielder. I do not have reports on his infielding acumen.

Three More

Corbin Carroll, ARI (22): Although there was little doubt Carroll would start for the 2023 Diamondbacks, the Varsho trade all but ensures an Opening Day role. A line drive machine with excellent discipline in the minors, Carroll had a mixed debut. His 130 wRC+ in 115 big league plate appearances belied below average exit velocities and merely average discipline. Look for those traits to dramatically improve throughout 2023.

Dominic Fletcher, ARI (25): Another “winner” of the Varsho trade, Fletcher no longer has an entire squadron of outfielders ahead of him on the depth chart. Should Alek Thomas continue to struggle and Jake McCarthy suffer a sophomore slump, then Fletcher might just worm his way into the Arizona lineup. Likelier, he’ll serve as trade bait. The Diamondbacks still need pitching depth.

Kumar Rocker, TEX (22): Kumar made his debut in the Arizona Fall League, pitching 14 innings with mixed results. His 18 strikeouts were encouraging, but they were offset by 12 walks and a 4.50 ERA. He appeared in the news this last week in connection to Carlos Correa’s delayed contract with the Mets. New York selected Rocker in the first round of the 2021 draft only to back out of their deal over concerns with his physical.

Latest On Potential Trade Scenarios For Marlins’ Rotation

By | at

It’s been widely reported over the past several months — really, dating back to last offseason — that the Marlins are open to dealing from their wealth of starting pitching depth in order to solidify other needs on the roster. That’s led to righty Pablo Lopez, who drew strong interest from the Yankees and the Dodgers at the trade deadline, being one of the most heavily speculated-upon trade candidates of the 2022-23 offseason. However, Barry Jackson of the Miami Herald writes in his latest Marlins notebook column that the team may be more open to moving left-hander Trevor Rogers than Lopez.

The 25-year-old Rogers is coming off a down year — nowhere near the excellent season enjoyed by Lopez — but would appeal to other teams in a different capacity. While acquiring Lopez would likely require trading a bevy of prospects for a pitcher at his value’s peak, Rogers is more of a buy-low option on the heels of a down 2022 season. The former first-round pick was an All-Star and the NL Rookie of the Year runner-up to Jonathan India in 2021, when he tossed 133 innings of 2.64 ERA ball with a hefty 28.6% strikeout rate and a solid enough 8.4% walk rate.

The 2022 season was a brutal sophomore campaign for Rogers, however. Back spasms and a lat strain prompted a pair of IL stints for the 6’5″ lefty, and his results when healthy enough to take the mound didn’t even come close to that brilliant rookie output. In 107 innings, Rogers worked to a 5.47 ERA that was more than double his 2021 mark, and his strikeout rate fell by more than six percentage points (to 22.2%) while his walk rate crept up to 9.4%. After allowing just 0.41 homers per nine innings in 2021 (1.1% of his opponents took him deep), Rogers yielded an average of 1.26 homers per nine frames (3.1%).

In addition to the discrepancy between the pair’s 2022 seasons, Lopez is under team control for only two more years and is projected by MLBTR contributor Matt Swartz to earn $5.6MM in his second year of arbitration. Rogers, meanwhile, is not yet arbitration-eligible and can be controlled for another four seasons. Both players would be highly appealing to the majority of clubs seeking rotation help this offseason, but a win-now club might feel better about plugging the veteran Lopez into its rotation, as he’s coming off a career-high 180 innings and has worked to a combined 3.52 ERA (3.48 FIP, 3.69 SIERA) over his past three seasons.

As was the case last offseason, it’s not a lock that the Marlins will trade any of their current big league rotation options. Many similar rumblings echoed throughout the 2021-22 offseason, but at the end of the day, the most notable arm the Fish had moved was right-hander Zach Thompson, who’d been their fifth starter. That the Marlins are open to moving Lopez and perhaps even more open to moving Rogers is notable, but that hardly means they plan to shop either pitcher and trade him for the best offer.

Rather, Miami appears likely to again set its sights on solidifying its center field vacancy this offseason. That didn’t transpire last year, and the team instead relied entirely on in-house options — most of whom were corner outfielders that were clearly miscast in center. Jesus Sanchez, former top prospect JJ Bleday and Bryan De La Cruz all logged significant time in center, but none of that trio drew particularly strong defensive grades for their efforts there.

Looking ahead to 2023, Miami will have to hope for better results from Avisail Garcia in one corner outfield spot and could again look to the trio of Sanchez, Bleday and De La Cruz as outfield components — though this time more likely in whichever corner is not occupied by Garcia. Jackson writes within his column that the bulk of Jorge Soler’s playing time will likely come at designated hitter next season, so he looks like an occasional outfield option, at best.

While center field is perhaps the most obvious area of need, Miami could also use upgrades at a variety of positions. Third base seems like another possible focus, and Miami lacks an obvious first baseman aside from Garrett Cooper, who’s been a candidate to be traded himself dating back to the deadline.

Of course, most fans salivate over the mere notion of 2022 NL Cy Young winner Sandy Alcantara being made available in a trade, but with four years remaining on an affordable contract, there’s little to no hope of such a scenario actually transpiring. Alcantara is a veritable lock to be Miami’s Opening Day starter in 2023, and if Lopez isn’t traded, he’ll presumably slot into the second spot in the rotation. The Marlins will also lean on a resurgent Jesus Luzardo and hard-throwing righty Edward Cabrera — a longtime top prospect who broke out with a 3.01 ERA in 14 starts last year.

Rogers and fellow southpaw Braxton Garrett are the favorites to occupy the fifth spot in the rotation, particularly with top prospects Max Meyer (Tommy John), Jake Eder (Tommy John) and Sixto Sanchez (shoulder) all recovering from surgery. Right-hander Eury Perez reached Double-A at just 19 years of age in 2023 and could be another rotation option before long; he’s widely considered to be among the ten best prospects in all of baseball and, unsurprisingly, is considered squarely off the table (as is the case with Alcantara), per Jackson’s report.

Big Hype Prospects: Meyer, Pratto, Ruiz, Greene, Cowser

By | at

This week in Big Hype Prospects, we’ll check in with a few recent and upcoming promotees along with a smattering of others.

Five Big Hype Prospects

Max Meyer, 23, SP, Marlins
AAA: 58 IP, 10.09 K/9, 2.95 BB/9, 3.72 ERA

Meyer is poised for his first taste of the Majors on Saturday, just ahead of the All-Star Break. As MLBTR’s Anthony Franco explored at the time his promotion was announced, the northpaw has made short work of minor league opponents at all stops. His ascent has not been without caveat. Some commentators worry about his ability to hold down a rotation role in the Majors for three reasons. The first is easiest to dismiss as unnecessary fretting. At 6’0’’, Meyer is slightly undersized which can presage an inability to tolerate 180-inning workloads. That said, there are plenty of “short” pitchers in baseball history, most notably Pedro Martinez.

The second and third issues are a bit more worrisome. They tie together, too. Meyer’s fastball command isn’t as sharp as his walk rates suggest. He’s gotten away with using it in the zone in the minors, but he could run into some trouble in the Majors. He relies almost exclusively on his fastball and an elite slider, a combination which often portends a future in the bullpen. That said, lower caliber pitchers like Brad Keller and Brady Singer have managed mid-rotation quality results with the same repertoire. We’ve also seen a few others like Spencer Strider thrive this season while using a different two-pitch repertoire.

Nick Pratto, 23, 1B, Royals
AAA: 337 PA, 17 HR, 8 SB, .240/.373/.484

Like many of his power-hitting Major League colleagues, Pratto got off to a slow start this season before eventually finding his stride. The Royals have promoted him for a series in Toronto in which they’ve infamously left 10 players south of the Canadian border. As such, his debut might be short-lived.

Pratto is a classic patient, left-handed slugger in the mold of Kyle Schwarber. Like the upcoming Home Run Derby participant, Pratto runs a mid-teens walk rate while striking out in around 30 percent of plate appearances. He makes up for so little contact by punishing those with which he does connect. Nearly half of his batted balls are flies and over 20 percent of those leave the yard. Per a home run calculator I’ve developed, Pratto projects for 33 home runs per 600 plate appearances. While he’s shown a willingness to run, he has below average speed. Like Schwarber, Pratto will probably be a volatile performer whose carrying trait is slugging.

Esteury Ruiz, 23, OF, Padres
AA: 232 PA, 9 HR, 37 SB, .344/.474/.611
AAA: 142 PA, 4 HR, 23 SB, .315/.457/.477

Ruiz draws his hype from our friends in the fantasy baseball realm where his combination of power and speed could make him one of the most celebrated players in the game. From a real-world perspective, there are a lot of things that could go wrong. Starting on defense, he only has about a year of experience as an outfielder. His routes can be inconsistent or even circuitous. Fortunately, he has enough speed to recover while he learns the position. Speed doesn’t guarantee eventual mastery as an outfield defender. Roman Quinn is similarly fleet and still takes baffling routes to the ball at times.

Scouts also worry about his hit tool. Prior to this season, Ruiz had consistently below-average plate discipline. He struggled with swinging strikes, strikeouts, and consistency of contact. Notably, he’s produced 13.9 percent walk and 17.4 percent strikeout rates this season across two levels. His swinging-strike rate has also improved. Perhaps a more selective approach has yielded better contact results (I’m still awaiting comment from my sources). Regardless, speed is his carrying trait. Nabbing 60 bases (69 attempts) in 374 plate appearances is seriously impressive work.
I’m reminded of Michael A. Taylor, an outfielder who, at his peak, occasionally hit for power, often stole bases, but never quite made enough contact to stick as a regular. He’s carved out a nice career based on gold glove caliber center field defense. As noted above, Ruiz will need to improve considerably to match Taylor on defense. The raw tools are there.

Riley Greene, 21, OF, Tigers
MLB: 109 PA, 1 HR, 1 SB, .255/.358/.340

Greene’s prospect eligibility will soon expire. His first taste of the Majors has yielded mixed results. On the one hand, he’s effectively working counts. His 21.1 percent strikeout and 7.9 percent swinging-strike rates exceed even the wildest hopes for his early-career performance. The swinging-strike rate, in particular, is a marked divergence from expectations.

On the other hand, Greene is supposed to be a power hitter. With just one home run, three doubles, and a triple to his name, he’s been one of the most punchless batters since his debut in mid-June. Only 19 players have a lower ISO over that span – mostly names like Geraldo Perdomo, Myles Straw, and Steven Kwan.

Better times likely await ahead. Greene is making consistent hard and barreled contact. It’s also encouraging to see him make adjustments. He’ll need to continue to do so to correct for the biggest flaw in his profile – an over-50 percent ground ball rate. While he’s currently using a shift-proof all-fields approach, he’s the kind of hitter who could benefit from a more pull-centric profile.

Colton Cowser, 22, OF, Orioles
High-A: 278 PA, 4 HR, 16 SB, .258/.385/.410
AA: 53 PA, 3 HR, 1 SB, .308/.491/.615

In a crowded Orioles system, a lot of attention is paid to Adley Rutschman, Gunnar Henderson, Grayson Rodriguez, and DL Hall. However, Cowser is also a Top 50-caliber prospect who is quickly working his way towards a big league debut in early 2023. With a patient approach, good rate of contact, and a swing geared for high BABIPs, Cowser profiles as a top-of-the-lineup force. He produces premium line-drive rates while using an all-fields approach. A left-handed hitter, he won’t be as penalized by the new dimensions at Camden Yards as his right-handed hitting teammates. Yet, since he hits to all fields, he’ll still use the spacious left field pasture to splash doubles.

If Cowser has a shortcoming, it’s that he doesn’t consistently get to in-game power. As mentioned, his swing skews to low-angle contact. He produces plenty of well-hit balls, but his game is mostly geared around reaching base. In today’s MLB, you never know when a player will make an adjustment that unlocks another gear, but it’s not strictly necessary in Cowser’s case. The Orioles have plenty of mid-lineup bats penciled into their future lineups. However, they could use a leadoff hitter who works counts and jumps on mistakes in the zone.

Five More

Michael Massey, Royals (24 years old): Another temporary beneficiary of the Royals’ roster triage, Massey isn’t technically a hyped prospect. However, my best scouting resource has been talking him up for a full year as a future regular. While it isn’t the most exciting profile, he skews to line drive and “fliner” contact which helps him to run high BABIPs while also regularly hitting for extra bases. The elevated BABIP will be necessary if he’s to be an above average hitter – his plate discipline and contact skills are slightly below average. Defensively, he profiles as a utilityman who fits best at second base.

Eury Perez, Marlins (19): With Shane Baz returning to the injured list due to an ominous elbow sprain, Perez is the last truly elite pitching prospect (Baz, Daniel Espino, and Grayson Rodriguez) left standing. The Marlins are carefully managing his workload – both by holding him to around 20 batters faced per appearance while using him every seven or eight days. He’s carved through Double-A competition and could probably more than hold his own in the Majors. He’s only 19 years and three months old, so Miami is taking the long view with his development.

Jordan Walker, Cardinals (20): Walker has yet to appear in this column for two simple reasons. His performance hasn’t merited effusive praise or words of caution. As one of the youngest players in Double-A, he’s batting .302/.392/.476 with seven home runs and 15 steals while demonstrating good strike zone judgment and a batted ball approach based around liners and ground balls. His light-tower power is handicapped by hitting too many grounders. It’s not a death blow to his presumed future as a top slugger. Aaron Judge, Giancarlo Stanton, and Vladimir Guerrero Jr. are among the notable power hitters who skew to low-angle contact.

Mick Abel, Phillies (20): With the usual caveats about injury, Abel will be one of the most-hyped pitching prospects this time next year. He’s performed well though not exceptionally at High-A this season, producing a 4.23 ERA with 10.50 K/9 and 3.95 BB/9. Recently, he’s struggled with both home runs and walks. The Phillies have allowed him to pitch surprisingly deep into his starts. He often faces 24 or more batters, which is more than the average big leaguer. This workload has been mitigated with extra rest between starts.

Brayan Rocchio, Guardians (21): Since a four-hit, two-homer game at the end of June, Rocchio is batting .452/.500/.833 over his last 46 plate appearances. In his second stint at Double-A, he’s noticeably improved upon his walk and strikeout rates. He’s beginning to track as a shortstop whose defensive and offensive prowess will remind Guardians fans of Francisco Lindor. Including last season, he now has 506 plate appearances at Double-A. A promotion to Triple-A is almost certainly imminent.

Big Hype Prospects: Cruz, Abrams, Volpe, Veen, Wiemer

By | at

This week, we investigate a mix of prospects at a wide range of levels.

Five Big Hype Prospects

Oneil Cruz, 23, SS, Pirates (MLB)
(AAA numbers) 247 PA, 9 HR, 11 SB, .232/.336/.422

When Tim Dierkes suggested I run this column, Cruz was his first example of the type of player he wanted to see covered. I’d previously written a fantasy column about “Peripheral Prospects” in this same format covering lesser-known guys like Ken Waldichuk and Brett Kerry. It’s only fitting to touch upon Cruz one more time. While his Triple-A numbers don’t jump off the page, he eventually settled in to the level. Since early-May, he’s batted .280/.374/.520 with an 11.4 percent walk rate and 17.7 percent strikeout rate. Reportedly, he was disappointed by his initial demotion, and it contributed to his April-long slump.

Since rejoining the Majors, Cruz is 4-for-18 with a stolen base. In four games, he’s already hit four balls over 100-mph, including two lasers over 110-mph. This is consistent with his track record. Cruz is built like a young Aaron Judge, and he hits the ball nearly as hard. His typical angle of contact is geared towards ground ball and line drive contact which could limit his home run production. When he does lift the ball, you can expect to see it soar. Anytime he’s in the lineup, Cruz is one of the most fascinating players in the league.

C.J. Abrams, 21, SS, Padres (MLB)
(AAA numbers) 151 PA, 7 HR, 10 SB, .314/.364/.507

Like Cruz, Abrams had a previous brief taste of the Majors and recently returned for four games. He’s 2-for-15 with one strikeout. Unlike Cruz, his exit velocities have been outright poor – just 81.8-mph. Abrams’ selection to the Padres roster followed on the heels of a particularly torrid multi-week stretch. He hit .398/.442/.519 over his last 95 Triple-A plate appearances. Included in the fun were four home runs, a 5.3 percent walk rate, and an 11.6 percent strikeout rate.

Such production indicated immediate readiness, especially for a prospect of Abrams’ caliber who scouts adore. If there’s a shortcoming in his profile, it’s that he doesn’t walk. It’s not necessarily an issue of discipline. He expands the zone in part because his speed has allowed him to still reach base in the minors. It’s possible he’ll learn to lay off marginal pitches in the Majors to improve his outcomes. If he does, he’ll flower into a high-quality leadoff hitter. There are still questions about his eventual defensive home – and not only because he has to share a field with Fernando Tatis Jr.

The worst-case scenario for Abrams is as an over-aggressive, contact-oriented slasher who plays all over the field. Between injuries and his incredible talent, we haven’t seen Abrams make many adjustments as a professional.

Anthony Volpe, 21, SS, Yankees (AA)
270 PA, 9 HR, 25 SB, .233/.326/.427

Over the offseason, I was virtually cornered by several Yankees fans who not-so-calmly explained that Volpe was the best prospect since Mike Trout. To the glee of everybody who loves to hate the Yankees, he performed particularly poorly until mid-May. Through May 17, he slashed a meager .170/.297/.330. Optimists cited four reasons he would rebound. First, the talent remained evident. He was working counts (13.8 percent walk rate). His .195 BABIP indicated poor luck. Lastly, he wasn’t the first prospect to wilt in chilly early-season weather.

As the calendar has heated up, so too has Volpe. He’s slashing .292/.356/.517 since May 18, a span of 132 plate appearances. He’s also putting more balls in play (6.8 percent walk rate, 15.9 percent strikeout rate) with a normal .319 BABIP. Volpe is on the shortlist for top prospect remaining in the minors. He’s also making a strong case for promotion to Triple-A – possibly by the end of this month.

Zac Veen, 20, OF, Rockies (A+)
258 PA, 8 HR, 25 SB, .259/.368/.440

The Rockies don’t exactly have an illustrious reputation with prospects. It’s nice to see Veen continue to perform to his draft pedigree. Scouting reports uniformly express concern about his hit tool playing against elite competition. While he possesses considerable raw power, his swing has qualities that some might describe as grooved. Such hitters can still succeed in the Majors. Billy Wagner once ridiculed Pat Burrell’s one-path swing (after allowing a home run). Joc Pederson might be a more relevant groovy comparison as a left-handed hitter with a pretty, loopy swing.

In any event, Veen is on track to spend some time in Double-A this season and debut either late in 2023 or early 2024. He works counts (14.3 percent walk rate) though he is also whiff prone (23.6 percent strikeout rate, 14.3 percent swinging-strike rate). While he’s 25-for-26 on the basepaths this season, it’s not clear if Veen will continue to run as he moves up the organizational ladder.

Joey Wiemer, 23, OF, Brewers (AA)
267 PA, 15 HR, 20 SB, .272/.348/.531

A divisive prospect, Wiemer is gaining steam as one of those guys who might succeed – perhaps even thrive – despite glaring flaws. He changed his mechanics heading into 2021 and unlocked massive in-game power. He launched 27 home runs in 472 plate appearances last season before tearing through the Arizona Fall League – one home run and a .467/.568/.667 triple-slash in 30 plate appearances.

There’s question if the hit tool will play in the Majors, but the power is evident enough to easily support a low-average approach. A worst-case scenario might look something like Adolis Garcia with plate discipline. Or Adam Duvall with discipline and an eagerness to run. He sells out for pull-side, fly-ball contact. He’s posted high BABIPs at every level, but this is a hitting profile that usually yields low BABIPs due to a cacophony of pulled grounders and easy fly outs. We should see him tested in Triple-A before long. Milwaukee might even need his help in the Majors late in the season if they don’t add outfield depth at the trade deadline.

Having watched him play several games, the energy he gives off evokes Bryce Harper.

Five More

Gunnar Henderson, Orioles (21): Last week’s lead BHP (that’s Big Hype Prospect), I noted Henderson would soon jump from around the 50th prospect to somewhere in the Top 10 as listmakers prepare their midseason updates. Since then, Baseball Prospectus’ Jarrett Seidler indicated Henderson might be the top prospect left in the minors. A highly-placed source at another major industry outlet confirmed Henderson is on a shortlist of about five players for their top prospect. As I understand it, this excludes all prospect-eligible players currently in the Majors like Michael Harris, Oneil Cruz, and C.J. Abrams.

Eury Perez, Marlins (19): Currently shredding Double-A hitters, Perez is perhaps the most-precocious pitching prospect since Julio Urias. While Urias’ development was eventually delayed by injuries, Perez remains both healthy and effective. Most of what I would say about Perez was gleaned from the Marlins system update posted to FanGraphs earlier today. So, I’ll let you read what Eric Longenhagen has to say directly.

Jeter Downs, Red Sox (23): Downs made his debut recently, struck out three times in four plate appearances, and was promptly optioned back to Triple-A. Once a fairly well-regarded prospect, he’s fallen off the map since joining the Red Sox in the Mookie Betts trade. He still possesses tantalizing power and speed along with decent plate discipline. Unfortunately, there’s a ton of swing-and-miss in the profile; the kind that’s readily exploitable by seasoned pitchers. The best-case scenario these days is a sort of Dylan Moore-like outcome.

Brett Baty, Mets (22): Baty was, for me, the most visibly impressive prospect in the Arizona Fall League. Like Volpe, he had a chilly start to his Double-A campaign – his second visit to the level. He currently has a 14-game hitting over which he’s tamed his strikeout rate and pulled his season-long batting line up to an above-average .282/.372/.450 performance. Like the most of the other Double-A bats we’ve profiled today, he’s seemingly on the cusp of a promotion.

Noelvi Marte, Mariners (20): Two weeks ago, I noted some in the scouting biz had indicated Marte’s early-career dominance might be linked to physical traits that won’t necessarily scale as he advances to higher levels. In plain English, the boy got big young. Last week, I issued something of a retraction because I’d misplaced my source. Since then, I rediscovered the initial note, and it comes from a highly reputable source with access to dozens of scouts. All of this is to say that Marte doesn’t seem to be the second-coming if you buy into this early-development narrative. Not everybody does! This has been the most contentious take to appear in BHP. I look forward to fomenting more discussion about Marte. For what it’s worth, his June-long slump has continued. He hit .214/.241/.250 over the last week and is at .191/.257/.324 for the month.

Big Hype Prospects: Thompson, Rodriguez, Pratto, Perez, Bello

By | at

This week, we take one last check-in on an uber-prospect then turn our attention to new fast-risers.

Five Big Hype Prospects

Zack Thompson, 24, SP, STL (AAA)

44.1 IP, 11.37 K/9, 3.05 BB/9, 4.67 ERA

The Cardinals recently announced Thompson will join the Major League roster, presumably to start one of the games this weekend. Reading the tea leaves, this might be a single-appearance arrival in the big leagues. He should eventually be a fairly regular member of the rotation at times during this season. Like fellow left-handed Cardinals pitching prospect Matthew Liberatore, Thompson’s individual pitches draw strong grades from scouts. However, the repertoire as a whole might leave something to be desired, especially since his fastball and curve don’t tunnel effectively. In other words, they look different out of his hand. That could partly explain his elevated Triple-A ERA despite strong strikeout and walk rates.

Liberatore, a 22-year-old former Rays farmhand, was dinged for a 5.54 ERA in three starts and generated just 6.1 percent swinging strikes. Scouts from multiple outlets have noted the similarities between these left-handed starters. We’ll see if Thompson can make a stronger claim to Major League readiness.

Julio Rodriguez, 21, OF, SEA (MLB)

205 PA, 6 HR, 15 SB, .272/.322/.424

Through the first two weeks of the season, Rodriguez hit a miserable .154/.233/.179 with a 41.9 percent strikeout rate. He struggled, in part, with bad strike calls. Since then, the precocious prospect is batting .303/.346/.487 with all six of his home runs and 11 steals. His strikeout rate during that span is down to 25.9 percent and slowly improving as the season progresses. He’s rapidly establishing himself as one of the most dynamic players in the league.

The obvious next step in his development is improved plate discipline. Rodriguez drew a healthy number of walks in the minors last season, though that could have been a function of opponents working around him. Thus far, he’s proven especially susceptible to swinging outside of the zone. His early experience with egregious strike calls might have taken a mental toll. If he can improve to even a league average swing rate outside the zone, superstardom will be his.

Nick Pratto, 23, 1B, KC (AAA)

186 PA, 10 HR, 4 SB, .221/.349/.461

Prior to this season, Pratto was seen as ahead of teammate Vinnie Pasquantino. Now, it’s not so clear. Both players are first basemen with sufficient thump to make their presence felt out of the designated hitter slot too. The trouble is the Royals entered 2022 with a logjam of cornermen and are resistant to setting aside their veterans. In particular, Carlos Santana has performed poorly since the start of 2020, batting just .203/.322/.311 in 1,061 plate appearances. Their loyalty in the face of contrary evidence is a factor in their 16-33 record.

While Pasquantino is having the spicier season, Pratto’s bat has come alive in the last two weeks. Over his last 59 plate appearances, he’s batting .217/.390/.565 with five home runs. He profiles as a slugger in the mold of Kyle Schwarber, one whose patience and penchant for fly ball contact will serve both as a strength (walks and home runs) and weakness (strikeouts and low batting average).

Eury Perez, 19, SP, MIA (AA)

38 IP, 13.26 K/9, 2.13 BB/9, 3.79 ERA

Unless I’m mistaken, Perez is the youngest member of Double-A, and he’s absolutely thriving. A looming 6’ 8’’ on the bump, Perez has uncanny command for a player his size and generates swinging strikes with ease. To that end, he’s recorded an 18.8 percent swinging strike rate against Double-A competition. He has a traditional repertoire of mid-90s fastball, curveball, and changeup. His build remains youthful. Given his height, Perez will probably add 30 or more pounds within the next couple years.

The Marlins have carefully managed his workload, keeping him to between 18 and 21 batters faced in most starts. In all probability, we won’t see Perez in the Majors this season. He might, however, find his way to the doorstep in time for an early 2023 debut.

Brayan Bello, 23, SP, BOS (AAA)

17 IP, 13.76 K/9, 4.24 BB/9, 3.18 ERA

The Red Sox have a number of interesting starting pitcher prospects headlined by Bello. While their big-league rotation is solid, they desperately need reinforcements in the bullpen. Bello kicked off 2022 in Double-A where he posted a 1.60 ERA with 11.23 K/9 and 3.21 BB/9 in 33.2 innings. He’s hardly missed a beat since joining the Triple-A rotation. A slight uptick in walk rate is the only sign he’s been challenged. Bello features a three-pitch repertoire of above average offerings. His fastball sits in the upper-90s and could play up in relief. He also throws a tight slider and a wipeout changeup.

Bello is poised to immediately reinforce the Red Sox pitching staff, either by joining the bullpen directly or freeing Garrett Whitlock to resume a late-inning role.

Five More

Grayson Rodriguez (22): Rodriguez was 20 batters into what many (including me) believe was his final minor league start when a lat strain ended his outing a few batters early. Such injuries can be complex and difficult to rehab. He’ll likely be shut down for at least several weeks before a throwing program is considered.

Ethan Small (25): Small received his first cup of coffee last Monday. He’s a southpaw whose fastball and changeup blend together beautifully even if they lack the big velocity associated with this era. His third pitch, a slider, lags behind the others. With Freddy Peralta and Brandon Woodruff sidelined, the Brewers might need Small again soon.

Taj Bradley (21): Bradley has built upon his breakout 2021 season with a mirror replica in Double-A. He’s posted a 2.20 ERA with 11.20 K/9 and 2.20 BB/9 in 41 innings. A promotion to Triple-A should be forthcoming, at which point he’ll become one of the youngest players at the level.

Gunnar Henderson (20): Speaking of young Double-A players on the cusp of reaching Triple-A, Henderson has put together an otherworldly .433/.500/.767 line over his last 30 plate appearances. Overall, he has more walks than strikeouts along with eight home runs and 12 steals in 200 plate appearances. A promotion is overdue.

Jordan Westburg (23): Although his overall performance hasn’t been as emphatic as Henderson’s, Westburg was just as hot since May 25. He’s batting .406/.486/.594 over his last 37 plate appearances. While Henderson appears to be mid-breakout, Westburg is merely showing modest skills growth.

Minor MLB Transactions: 8/3/17

Here are Thursday’s minor moves from around the game…

  • Per an announcement from the Indians, righty Perci Garner has been released after clearing waivers. Garner was designated for assignment recently. The 28-year-old cracked the majors briefly last year and showed well in the minors, but he has missed a lot of time in 2017 for injury reasons that remain less than clear. When he has pitched, his control issues have resurfaced. Through 14 1/3 Double-A frames, Garner permitted nine walks but also rang up 18 strikeouts while allowing five runs on only seven hits. But he managed to permit seven earned runs on only one hit in his three appearances at Triple-A, owing to eight free passes in just 1 1/3 innings.
  • The Marlins have acquired outfielder Eury Perez from the Pirates, per an announcement from the Indianapolis Indians. Perez had been playing for Indianapolis, the Bucs’ top affiliate, since joining the organization on a minors deal over  the winter. He has been productive at the plate (.336/.400/.433) continued to run wild on the bases (22 steals) in a fifty game sample. Perez has seen MLB action in four seasons, though he has just 156 total plate appearances — with a poor .254/.307/.282 batting line — at the game’s highest level.
  • The Tigers are set to select the contract of veteran right-hander Edward Mujica, reports SB Nation’s Chris Cotillo (on Twitter). The 33-year-old hasn’t pitched in the Majors since 2015, as he’s spent the past season plus between the Triple-A affiliates for the Phillies, Royals, Twins and Tigers. The former Cardinals closer has generally been excellent in Toledo this season, though, logging 46 innings with 7.4 K/9, 1.0 BB/9 and a 36.5 percent ground-ball rate en route to a 2.35 earned run average. He’ll join a Tigers ’pen that has an MLB-worst 5.18 ERA and recently traded its best reliever, Justin Wilson.

Pirates Sign Josh Lindblom, Eury Perez To Minor League Deals

By | at

The Pirates have inked right-hander Josh Lindblom and outfielder Eury Perez to minor league contracts with invites to Major League Spring Training, tweets MLB.com’s Adam Berry.

[Related: Pittsburgh Pirates Depth Chart]

The 29-year-old Lindblom was briefly a part of the Pirates organization in the 2014-15 offseason after Pittsburgh picked him up on waivers from the Athletics. However, the Bucs released Lindblom in order to allow him to pursue an opportunity in the Korea Baseball Organization, and Lindblom would go on to spend the next two seasons pitching for the KBO’s Lotte Giants. The 2015 campaign was a huge success for Lindblom, as he worked exclusively as a starter for the first time in his career and racked up a career-high 210 innings in the Giants rotation. That year also saw him record a 3.56 ERA — no small feat when considering the KBO’s hitter-friendly nature — with 7.7 K/9 against 2.2 BB/9. The 2016 season was more of a struggle, as Lindblom fought some control issues (3.8 BB/9) and saw his ERA jump to 5.27 while his innings total fell to 170 2/3. He’ll provide the Bucs with some depth in the ’pen and in the rotation in his return to the organization.

Perez, meanwhile, will presumably compete for a bench job in Spring Training and can report to Triple-A Indianapolis if he doesn’t make the team. The 26-year-old boasts blistering speed but has never hit enough to carve out a consistent role on a big league roster. His lengthiest (and most recent) MLB stint came in 2015 with the Braves, for whom he slashed .269/.331/.303 in 133 plate appearances over the life of 47 games. Perez comes with a very nice Triple-A track record — .298/.347/.393 with 111 steals in 336 games — and will vie for a fourth or fifth outfielder role. At present, Adam Frazier seems like the favorite to occupy that slot.

Minor MLB Transactions: 6/23/16

Here are the day’s minor moves:

  • The Rays have acquired outfielder Eury Perez from the Astros, per an announcement from Tampa Bay’s Triple-A affiliate. Cash considerations will go back to Houston in the deal. Perez, 26, received a career-high 133 plate appearances last year with the Braves, slashing .269/.331/.303 and swiping three bags. The speedy center fielder does bring value with the glove and on the bases, though, so he is at least a useful depth piece. Tampa Bay has dealt with a variety of injuries at the major league level, and was obviously looking to fill out its roster at Durham and ensure that it has options on hand. Perez owns a .267/.298/.385 batting line with nine steals in his 146 plate appearances at Triple-A this year.
  • Southpaw Darin Gorski has joined the Mets on a minor league deal, per an announcement from his independent league club, the Somerset Patriots. (Hat tip to Mike Ashmore of mycentraljersey.com.) The 28-year-old will head to Triple-A Las Vegas, which is where he spent last season. He moved to the indy ranks after putting up 137 innings of 5.52 ERA pitching there in 2015, with 7.1 K/9 against 4.5 BB/9. Those peripherals look about the same over his 60 1/3 frames for Somerset this year, though Gorski has tamped down the earned runs to under four per nine. New York originally selected him in the seventh round of the 2009 draft; this will mark his eighth season with the organization.

Astros Sign Eury Perez To Minors Deal

By | at

The Astros have announced the signing of outfielder Eury Perez to a minor league pact. Houston also added righty Cesar Valdez and invited both to major league training camp this spring.

Perez, 25, received his first chance at extended big league action last year with the Braves. Over 133 plate appearances, he slashed .269/.331/.303 and contributed three stolen bases. He was non-tendered by Atlanta earlier this winter.

While he’s always been light on power, the center field-capable Perez has shown quite a bit of speed in the minors and owns a .307/.358/.402 batting line in 1,115 Triple-A plate appearances. He was once a fairly highly-regarded prospect with the Nationals and could still have some function in the majors if he can reach base enough.

The 30-year-old Valdez saw brief MLB action back in 2010, but has pitched exclusively overseas since 2012. His return to affiliated ball was likely driven by his 2015 performance in Mexico. Working for the Olmecas de Tobasco, Valdez threw 160 2/3 innings in 23 starts and racked up 9.0 K/9 against 1.6 BB/9.

The ’Stros also announced their non-roster spring camp invites, which include some notable names from the minor league system. Among them are recent draft picks Alex Bregman and Derek Fisher as well as prospects A.J. Reed, Tony Kemp, Colin Moran, and J.D. Davis.

2015-16 National League Non-Tenders

By | at

Major League clubs have until 11pm CT tonight to tender contracts to players for the 2016 season. Remember that you can track all of the action using MLBTR’s Non-Tender tracker, and we offer a full list of non-tender candidates (in the estimation of MLBTR’s Tim Dierkes). Also important for reference is the set of arbitration salary projections from MLBTR and contributor Matt Swartz.

We’ll run down the list of National League non-tenders here, and update it as reports come in.

  • Pre-arb outfielder Eury Perez was non-tendered last night by the Braves, MLB.com’s Mark Bowman reports on Twitter. The 25-year-old could, in theory, have served as Michael Bourn’s backup in center, but it appears that Atlanta will look for an alternative.
  • The Rockies won’t tender contracts to left-handers Yohan Flande or Jason Gurka for the 2016 season, per a club announcement. The team also announced that outfielder Rosell Herrera will be non-tendered. Flande, 29, is the most experienced arm of the bunch, having soaked up 127 1/3 innings for Colorado over the past two seasons, albeit with a 4.95 ERA.
  • The Dodgers announced that they’ve non-tendered righties Juan Nicasio and Lisalverto Bonilla. Nicasio is a mild surprise considering the fact that he logged a 3.86 ERA with a robust 10.0 K/9 rate and a 2.83 FIP in 2015. However, he also averaged 4.9 walks per nine innings and had what was almost certainly unsustainable luck in terms of home runs, yielding just one big fly in 58 1/3 innings. The hard-throwing righty should garner some interest on the free-agent market.
  • The Marlins announced that they’ve non-tendered Aaron Crow, who missed the 2015 season due to Tommy John surgery. The team also formally announced its previously reported decision to non-tender Henderson Alvarez (more on that controversial decision here).
  • The Nationals will not tender right-hander Craig Stammen a contract for the 2016 season, per a club announcement. He missed nearly the entire season due to a pair of torn tendons in his right forearm that required surgery.

Earlier Updates

  • The Cubs announced that right-hander Ryan Cook has been non-tendered. An offseason waiver claim, Cook never suited up for Chicago. The former All-Star setup man yielded an astounding 18 earned runs in just 8 2/3 innings this season between Oakland and Boston.
  • The Giants have also non-tendered backup catcher Hector Sanchez, per a club announcement, which additionally confirmed Petit’s non-tender.
  • The Giants will non-tender right-hander Yusmeiro Petit, MLBTR’s Steve Adams reports (Twitter link). The right-hander has recorded a solid 3.66 ERA with 8.8 K/9 and 1.9 BB/9 across 245 2/3 innings for the Giants over the past four seasons while spending time in both the rotation and the bullpen. Ken Rosenthal of FOX Sports tweeted that Petit was offered to at least one other club in a trade, but clearly nothing materialized, as he’ll now hit the open market in search of new club.
  • The Brewers announced that they’ve non-tendered utilityman Elian Herrera. The 30-year-old was not yet arbitration eligible, but Milwaukee clearly preferred to keep the rosters spot open. Herrera hit .242/.290/.395 last season in a career-high 277 PAs, and GM David Stearns has interest in retaining him on a new minor league deal, tweets Tom Haudricourt of the Milwaukee Journal-Sentinel.
  • The Reds will not tender contracts to righty Ryan Mattheus, outfielder Ryan LaMarre, or righty Pedro Villarreal, C. Trent Rosecrans of the Cincinnati Enquirer reports on Twitter and the club has since announced. Of those players, only Mattheus was eligible for arbitration. The 32-year-old, who threw 55 innings and posted a 4.09 ERA last year, projected for a $1.3MM salary. LaMarre, 27, just cracked the MLB roster last year but spent most of the year at Triple-A. Villareal, also 27, notched a solid 3.42 ERA in his fifty frames in 2015, but his strikeout rates fell and ERA estimators did not smile upon the quality of his contribution.
