Big Hype Prospects: Baty, Miller, Dominguez, Cowser, Wiemer

By Brad Johnson | July 29, 2022 at 4:15pm CDT

This week on Big Hype Prospects, we’ll look at more prospects who could find themselves on the move in the next few days. Check out last week’s Juan Soto Edition of Big Hype Prospects for more deadline trade candidates.

Five Big Hype Prospects

Brett Baty, 22, 3B, NYM (AA)
350 PA, 14 HR, 1 SB, .303/.394/.507

The Mets are reportedly trying very hard to hang onto Francisco Alvarez and Baty. To accomplish all of their deadline trade goals, they might not be able to cling to both. Alvarez being the scarcer and flashier talent, I figure he’s less likely to be traded outside of a Juan Soto or Shohei Ohtani deal. Baty, however, would fit in a swap for any of the next tier of trade targets. Names like Luis Castillo, Frankie Montas, or Sean Murphy.

Baty is having a fine season after a bit of a slow start. His performance suggests a readiness for the next challenge. When I see a prospect of this caliber promoted slowly, it leads me to wonder if he’s been held down to ensure his trade value doesn’t take a hit from an untimely slump. Baty makes a ton of hard, low-angle contact. Despite a 26 percent strikeout rate, he regularly hits for a high batting average. He makes the most of his rare air-ball contact thanks to an over 20 percent HR/FB ratio. His batted ball profile reminds me of a slightly better Ryan McMahon.

Bobby Miller, 23, SP, LAD (AA)
76.1 IP, 11.20 K/9, 3.30 BB/9, 4.36 ERA

Miller receives plenty of attention for his triple-digit velocity heater, but his results don’t always match the raw stuff. This season, his ERA is a full point higher than his FIP. In the past, we would have shrugged and assumed better days awaited. Unfortunately, it seems his fastball shape and middling command are the culprits. Both issues, should they remain, will only intensify once he reaches the Majors. They could prevent him from realizing his full potential. While some kind of rotation role is likely with a floor as an elite reliever, now could represent a good time for the Dodgers to sell Miller. Some clubs might believe they can fix him.

If the worst outcomes are reminiscent of Sixto Sanchez or Hunter Greene, that’s not a bad thing. Sanchez, you might recall, was dealt for multiple seasons of J.T. Realmuto (the Phillies also included Jorge Alfaro, Will Stewart, and an international bonus slot in the deal). Miller might not be quite as beloved as Sanchez was at the time. His plus command helped assuage doubts about a modest strikeout rate. Still, that implies the Dodgers can expect to add a substantial player if they part with Miller.

Jasson Dominguez, 19, OF, NYY (A+)
(A) 423 PA, 9 HR, 19 SB, .265/.373/.440
(A+) 27 PA, 1 HR, 2 SB, .292/.370/.500

Dominguez is best-known for having the physique of a mid-20s body builder as a 17-year-old. Now 19, the developmentally mature teenager recently earned a promotion to High-A where he’s one of the youngest players on hand (recently promoted Jackson Chourio is the youngest player at the level). Reports heading into this season were mixed with some notes emphasizing his physicality as potentially detrimental. He’s put those concerns to rest while display above average plate discipline with plenty of blistering contact. Presently, he makes a lot of hard, low-angle, pulled contact. He has time to make adjustments to unlock either a more balanced or more power-centric approach.

Dominguez comes with substantial bust risk so any acquiring team should make sure they feel confident about their development staff.

Colton Cowser, 22, OF, BAL (AA)
(A+) 278 PA, 4 HR, 16 SB, .258/.385/.410
(AA) 98 PA, 7 HR, 1 SB, .324/.480/.689

Cowser is a personal favorite of mine. He has fantastic discipline, a better-than-average swinging strike rate, and a batted ball profile maxed out for high BABIPs. In short, he is the ideal leadoff hitter. His game is a little bit like Alek Thomas – if the DBacks outfielder took a lot more pitches. While an adjustment isn’t strictly necessary, Cowser could probably stand to swing more often. Adding in a little bit loft wouldn’t hurt either. There are a lot of directions this profile can go, and most of them yield some type of really useful ballplayer. To reach a superstar ceiling, he’ll have to take bold risks regarding his approach and mechanics.

Depending on who you talk to, Cowser is the Orioles third- or fourth-best prospect. With their surprise contention, the front office is undoubtedly kicking around ideas. From the perspective of continued employment, it’s safer for Mike Elias to stay the course. If they do spend prospects on reinforcements, they’ll likely either be from the bargain bin or club-controlled for a long period. In the latter scenario, some of their better names like Cowser, Coby Mayo, and Jordan Westburg will need to be in play.

Joey Wiemer, 23, OF, MIL (AA)
364 PA, 15 HR, 24 SB, .243/.321/.446

Wiemer has the look and the size of the notable prospect. At times, he puts up video game numbers as he did in High-A last season. Opinions are divided. Some scouts I spoke with last fall weren’t enamored with his playing style, believing he’d fade into a role player as he advanced through the system. Unaffiliated scouts who are plugged more into the fantasy baseball scene love his combination of power and aggression on the basepaths.

As reported earlier today, the Brewers are looking for mid-tier upgrades like Ramon Laureano. While the club would undoubtedly prefer to hold onto one of their few top prospects, they have one of the weaker farm systems behind Chourio. Their list of attractive trade assets might not extend much beyond Wiemer, Sal Frelick, and Ethan Small.

Five More

Kyle Harrison, SFG (20): In his latest outing – his first appearance since July 8 – Harrison fanned nine of 10 batters faced. It was a masterful performance. The soon-to-be 21-year-old is ready for the next challenge.

Oswald Peraza, NYY (22): With the Yankees eyeballing a late-October run, one of their young shortstops is probably going to wind up joining another club. While Peraza isn’t as impressive as Anthony Volpe, he still profiles as a future above average shortstop. He’s hit 13 home runs with 24 steals and a .258/.329/.446 triple-slash in 319 Triple-A plate appearances.

Royce Lewis, MIN (23): Lewis showed signs of a breakout in the spring of 2021 before missing the entire season. Then, after showing well in Triple-A and a 41 plate appearance stint in the Majors, he again suffered a season-ending injury. The Twins undoubtedly don’t want to sell Lewis. They stuck it out with Byron Buxton so it’s not as if they’re averse to players with the “injury prone” label. If they’re thirsty enough, he’s a highly valuable prospect who happens to be incapable of helping them contend this season.

Michael Busch, LAD (24): A Busch trade is beginning to feel inevitable. The oldest player featured today, Busch is having a decent but unspectacular campaign at Triple-A. He’s on a tear this month, batting .310/.384/.529 in July (125 wRC+). Since he looks like someone who might need awhile to adjust in the Majors, the Dodgers might prefer to skip that portion of his development by cashing out.

Ricky Tiedemann, TOR, (19): A youthful southpaw who has chewed through the competition, Tiedemann might just be the Blue Jays most sellable prospect. He has a bright and promising future after already succeeding in High-A as a teenager. However, TINSTAAPP applies, and the Jays current contention window may well be closed by the time Tiedemann is big league ready.

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

By Brad Johnson | June 24, 2022 at 6:50pm CDT

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.
