Nathaniel Lowe

The Rangers’ Breakout Slugger

By Steve Adams | September 6, 2022 at 9:14pm CDT

The Rangers’ shift from a rebuilding mindset into a win-now mode began in the offseason with a combined $556MM spent on Corey Seager, Marcus Semien and Jon Gray. It continued over the summer when Texas held onto several trade candidates of note (e.g. Martin Perez, Matt Moore) and overhauled their leadership; gone were manager Chris Woodward and longtime president of baseball operations Jon Daniels, leaving the team likely to conduct a managerial search this winter and leaving third-year GM Chris Young with full baseball operations autonomy.

Another aggressive winter seems likely, as the Rangers still have plenty of work to do on an improved but flawed roster. There’s been talk of a new contract with lefty Martin Perez, following his breakout in a return to his Rangers roots, but that’d only be one piece of the puzzle. There’s hope that Josh Jung will solidify third base, but there are questions behind the plate, in the outfield and on the pitching staff.

Nathaniel Lowe | Kevin Jairaj-USA TODAY Sports

Texas has currently dropped nine games in a row, erasing any delusions that perhaps this team may be turning the corner right now, but that doesn’t mean there aren’t bright spots to the season. Seager has hit well. Semien has shaken off a disastrous start and, since mid-May, looked quite strong. Gray has lived up to his own multi-year deal. Perhaps the brightest spot of all, however, has come in the form of a breakout for slugger Nathaniel Lowe.

Acquired in a Dec. 2020 trade that sent three minor leaguers to the Rays, the now-27-year-old Lowe had a solid but uneven first year in Texas. He homered six times in his first 22 games (98 plate appearances) as a Ranger before settling in at a more modest, but still productive pace. Lowe continued hitting well but “only” chipped in another 12 home runs over his next 544 plate appearances. He finished the year as a .264/.357/.415 hitter — 14% better than league average, by measure of wRC+.

For much of the 2022 season, Lowe looked quite similar; he posted a 115 wRC+ in the season’s first half slashing .270/.323/.429. Since the All-Star break, however, Lowe has been not only the Rangers’ best hitter, but one of the best hitters in Major League Baseball. He’s slashing an absurd .363/.414/.632 with 11 homers, nine doubles and two triples in just 186 plate appearances. In that time, 52.3% of the balls off his bat have been hit 95 mph or greater; his average exit velocity has spiked from 89.3 mph to 91.3 mph, and he’s gone from barreling 7.9% of the balls he puts into play to a much heftier 12.9%.

This torrid six-week stretch has bolstered Lowe’s season line to a robust .302/.355/.500, and he’s hitting .282/.356/.455 in a total of 1172 plate appearances since being traded to Texas in the first place.

This is probably the best stretch of Lowe’s big league career, but he’s been quietly productive from the day he got to the big leagues in 2019 and increasingly looks the part of a bona fide middle-of-the-order hitter. Skeptics will point to this year’s .358 average on balls in play and wonder when he might regress, but it’s not a given, or even likely, that he will. Lowe touts a .346 BABIP in 1417 career plate appearances, suggesting that he’s capable of sustaining a mark well north of the league average (.291 this season).

Unlike many players who keep their BABIP figures high, Lowe isn’t beating close grounders and getting there via his wheels; rather, he does so by effectively spitting on any shifts against him. Lowe leads the Majors in opposite-field hits dating back to 2021, and he’s tied with Giancarlo Stanton for the game’s third-base wRC+ mark when hitting to the ball the opposite way during that time (only Tim Anderson and Aaron Judge have been better).

Lowe has only been shifted in 20.1% of his plate appearances this season, which isn’t among the very lowest rates in the league but is well below the league average. Moreover, the only lefties who rank below him (min. 250 plate appearances) are Raimel Tapia, Nicky Lopez, Luis Arraez, Steven Kwan, Luis Guillorme, Luis Gonzalez, Joey Wendle, Michael Harris II, Adam Frazier, Eric Hosmer, Riley Greene, Brandon Nimmo, Brendan Donovan and J.P. Crawford. There are some good hitters in that bunch (Kwan, Arraez, Nimmo and Harris in particular), but it’s mostly a list of contact-oriented hitters who don’t pose much of a power threat. With the exception of Harris, there’s no lefty-swinging slugger in MLB who is shifted less frequently than Lowe.

Similarly, Lowe isn’t fazed by left-handed pitching. His 141 wRC+ mark against lefties over the past two seasons is 26th among qualified hitters and trails only Matt Olson, Yordan Alvarez and Anthony Rizzo for the top mark among left-handed hitters in that time. Again, it’s tempting to say there’s just been some small-sample, BABIP-related luck in play, but in 2022 Lowe has punched out less against fellow lefties and hit for more power than against southpaws than when holding the platoon advantage. It’s not a simple case of some bloop singles falling in and inflating his stat line; he’s genuinely been a better hitter against lefties this year.

If there’s a knock on Lowe’s game, it has nothing to do with his work at the plate. His defense, however, is quite suspect by most public measures. Defensive Runs Saved (-7) and Statcast (11 outs and 8 runs below average) feel he’s been among the game’s worst defenders at his position (or at any position, for that matter). No player in the Majors has made more errors at first since the start of the 2021 season than Lowe’s 20. (Miguel Sano is close, in far fewer innings, but the point stands.)

Even if there’s a move to more designated hitter work in Lowe’s future, though, his bat should more than carry him at that position. He doesn’t draw many walks but has above-average contact skills, even when chasing pitches off the plate, and his ability to flip balls out to left field (or, in some instances, crush them into the left-field seats) should serve him well in that capacity even if he never pares back his higher-than-average chase rate.

Although Lowe has now played in parts of four Major League seasons, he’ll finish out the 2022 campaign shy of three years of Major League service time. At two years, 145 days he’ll be a lock for Super Two status and reach arbitration this winter, where his power numbers and durability will serve him well. That shouldn’t matter much for a Rangers club that spent more than a half billion dollars in free agency that winter, and finishing at two-plus years of service means Lowe will be controllable for another four seasons, through his age-30 campaign.

The Rays deservedly have a reputation for being a risky team with which to trade, and there’s plenty of time for any of Heriberto Hernandez, Osleivis Basabe or Alexander Ovalles to make the trade look more palatable from their vantage point. All three are having strong seasons, and Hernandez in particular is ranked anywhere from 23rd (Baseball America) to eighth (FanGraphs) among Tampa Bay farmhands. But as things stand right now, the Rangers have a middle-of-the-order complement to Semien and Seager for the next four years, and they’re not desperately missing any of the players they surrendered to acquire him.

No Immediate Plans For Mitch Garver To Return To Catcher

By Anthony Franco | May 26, 2022 at 2:29pm CDT

Two weeks ago, the Rangers placed catcher Mitch Garver on the 10-day injured list with a flexor sprain in his throwing forearm. That proved a minimal stay, as he was back on the roster in short order, but he’s not likely to return behind the dish any time soon.

Garver has worked exclusively as a designated hitter in the six games since returning from the IL, and he tells Evan Grant of the Dallas Morning News he’s expecting to remain in the bat-only role for the time being. The organization doesn’t have plans for Garver to begin an imminent throwing program, and Grant suggests it’s possible the 31-year-old could be limited to DH or first base for the entire season. That’s not definitive, but in any event, it seems unlikely we’ll see Garver donning the tools of ignorance anytime soon.

Texas manager Chris Woodward has nevertheless penciled him into the lineup for all six games since his return from the IL. That’s a testament to his offensive productivity, particularly from a power perspective. Garver is only hitting .220 with a .298 on-base percentage, but he’s popped six home runs and a trio of doubles to post a .430 slugging percentage that’s well north of the .382 league mark. He’s shown no ill effects of the injury offensively, hitting three homers within the last week.

When the Rangers acquired Garver from the Twins for shortstop Isiah Kiner-Falefa over the offseason, they no doubt envisioned him as their primary catcher. That he’s only managed 14 starts behind the plate and won’t be able to get back imminently is a bit disappointing, but the blow has been softened by excellent starts from their other backstops.

Jonah Heim, acquired from the A’s last February in the Khris Davis — Elvis Andrus swap, has made a team-leading 23 starts at catcher. The 26-year-old is sporting an excellent .270/.356/.494 line, collecting five homers of his own. More importantly, Heim has more than doubled his walk rate relative to last season while slicing his strikeouts by more than five percentage points. After hitting .196/.239/.358 last season, the 26-year-old looks to have made strides from a plate discipline and power perspective. He probably won’t keep hitting at this pace, but he’s earned the opportunity to continue playing regularly.

Meanwhile, 24-year-old Sam Huff is up as Heim’s backup after hitting .260/.349/.575 in 19 games with Triple-A Round Rock. Huff only has 18 games of MLB experience under his belt, but he’s been regarded as one of the better prospects in the system for a while. Evaluators have long raved about his right-handed power potential, although he’s faced some questions about his receiving ability and lofty strikeout totals in the minor leagues.

While a Heim — Huff pairing isn’t the most proven group, there’s obvious upside with both players. Despite an active offseason, Texas is still using 2022 as primarily an evaluative season with an eye towards more earnest contention next year and beyond. They’ll welcome the opportunity to get younger players like Heim and Huff into the lineup so long as both are performing well, but Garver’s (at least immediate) move down the defensive spectrum will necessarily come at the expense of a few others.

As Grant covers in a second piece, that could mean fewer starts for Nathaniel Lowe and Andy Ibáñez, in particular. Lowe has been the team’s primary first baseman after a solid .264/.357/.415 showing last season. He’s not off to a good start, though, with just two homers and a .245/.300/.317 line through 150 trips to the plate. The left-handed hitting Lowe has made virtually zero impact from a power perspective, and he’s seen his walk rate fall as he’s gotten more aggressive. Huff got the start at first base against Angels left-hander Reid Detmers last night, and Grant suggests he could see more time there — particularly against southpaws.

“I still believe Nate Lowe is an everyday talent,” Woodward told reporters yesterday. “He just hasn’t performed the way we’ve [expected]. I’ve been really honest with all of our guys about that. I think it’s really important to set a standard there. When you aren’t performing and somebody else is, I have a responsibility to the team.”

With Garver commanding everyday reps at DH, Lowe’s only real path to playing time is at first base. Ibáñez’s ability to play third base and the corner outfield could afford him a bit more run, but he’s off to an even worse start at the plate. Through 107 plate appearances, Ibáñez is hitting just .180/.234/.230. Among 244 hitters with at least 100 plate appearances, only four have been less productive offensively by measure of wRC+. Woodward also expressed faith in Ibáñez’s ability to turn things around, but he’ll no doubt need to start performing better if he’s to hang onto his near-regular role.

Rangers Expected To Explore Matt Olson Deal Post-Lockout

By Steve Adams | February 9, 2022 at 9:34am CDT

Whenever the lockout ends, transactions — both on the trade and free agent fronts — figure to pile up in a hurry. Among the likelier names to change hands is star Oakland first baseman Matt Olson, who has been the subject of rumors for several months. That’s only natural after A’s GM David Forst plainly acknowledged that the team has reached a point in its “cycle” where they’ll need to be open to moving established players (though the writing had already been on the wall for some time before that).

The Yankees have been frequently reported as an interested suitor for Olson, and prior to the lockout, Evan Grant of the Dallas Morning News wrote that the Rangers had “already begun investigating” what an Olson acquisition might cost them. Whatever exactly occurred in those pre-lockout talks seemingly wasn’t a huge deterrent, as Grant writes this week that Texas will “absolutely” circle back with the A’s to see if there’s a potential fit.

Perhaps of greater intrigue to fans, however, is that Grant suggests an Olson package would require, at minimum, current big league first baseman Nathaniel Lowe, plus of the organization’s top prospects and a pair of other mid-tier names from down on the farm. As one might expect, it’s a rather broad and subjective set of parameters. Josh Jung and Justin Foscue are both “top prospects” for the Rangers, for instance, but Jung’s value is considerably higher at the moment. It’s hard to see the Rangers parting with Jung, who’s expected to debut in 2022, or either of the top pitching prospects in the system (2021 No. 2 overall pick Jack Leiter and 2018 first-rounder Cole Winn).

Regardless of specific permutations on the prospect side of things, a package headlined by Lowe and two or even three intriguing farmhands would figure to be appealing to A’s brass. Lowe, 26, isn’t on the same level as Olson offensively or defensively, but he’s been an above-average hitter in the big leagues and is controlled another five seasons. He’ll likely be a Super Two player (assuming Super Two designation remains unchanged in current labor talks), thus putting him on a path to arbitration eligibility next offseason. Lowe’s first two or even three arbitration salaries should be relatively affordable, however.

Texas acquired Lowe in a Dec. 2020 trade that sent four prospects to the Rays, and he responded with a solid first year at the plate in his new environs. Through 642 plate appearances, Lowe slashed .264/.357/.415 with 18 home runs, 24 doubles, three triples, eight stolen bases (in eight attempts) and a hearty 12.5% walk rate. Lowe had fanned in 31.8% of his first 245 trips to the plate in Tampa Bay, but he dropped that number to a more manageable 25.8% in Texas. Defensively, he put up sub-par marks in Defensive Runs Saved (-3), Ultimate Zone Rating (-4.2) and Outs Above Average (-3). Scouting reports from Lowe’s prospect days pegged him as a solid defender at first base, however, so there’s likely some room for improvement.

Notably, Grant adds that if Olson isn’t acquired, first base isn’t likely to be a priority for the Rangers. A pursuit of Olson, then, seemingly isn’t about being dissatisfied with the work Lowe has put in, but rather about jumping at the opportunity to grab an elite player with multiple years of club control remaining.

While there’s no guarantee Olson is ultimately moved, it’s an interesting look at a potential framework for a swap. The A’s have, historically speaking, tended to prefer returns that included immediate help for the big league roster when dealing away star players. Lowe would certainly fall under that umbrella, and some immediate production from him could help to soften the blow of losing Olson.

Olson, 28 next month, has emerged as one of the premier first basemen in the game over the past few years, with his 2021 season in particular towering above the rest of the league. In 673 plate appearances, Olson batted .271/.371/.540 (146 wRC+) with 39 home runs, 35 doubles and standout defense at first base. He dramatically reduced his strikeout rate, cutting it from 26.1% (2016-20) all the way to 16.8% — and he did so without sacrificing any of his plate discipline. To the contrary, Olson’s walk rate jumped from 10.8% in 2016-20 to 13.1% this past season.

Trading a player of this caliber is a tough pill for the A’s to swallow but also, as Forst alluded to, a familiar process in the Oakland front office. Olson is due his second arbitration raise once the lockout ends, and MLBTR contributor Matt Swartz projects that he’ll jump from $5MM to $12MM for the 2022 season. Add in a third and final arbitration raise in 2023, and Olson figures to cost upwards of $30MM over the next two seasons combined.

That’s a bargain rate for most clubs, but for a perennially low-payroll A’s team that has seen its best players reach the late stages of arbitration simultaneously, it’s a problematic scenario. Olson, Matt Chapman, Sean Manaea, Chris Bassitt and Frankie Montas are projected to combine for $45.7MM alone; the A’s payroll is set to rise to its second- or third-highest mark ever in 2022 before the team even makes a single addition.

Trading Olson within the division may not be preferable for the A’s, but longtime baseball ops boss Billy Beane and Forst have never shied away from intra-division swaps. Texas and Oakland lined up on a deal just last offseason, swapping out Elvis Andrus and Khris Davis in a financially-motivated arrangement. A year prior, Texas and Oakland matched up in a Mike Minor swap, and the two teams also struck an accord in the 2019-20 offseason when Jurickson Profar went from Texas to Oakland as part of a three-team trade. Suffice it to say, Beane and Rangers president of baseball operations Jon Daniels are comfortable trading within the division, although moving a star of Olson’s caliber perhaps changes that calculus a bit.

If the Rangers were to ultimately pry Olson loose from their divisional foe, one would have to imagine they’d take a run at signing him to a long-term extension. They still have a ways to go before stepping back into the AL West running and aren’t yet expected to contend in 2022, so losing any trade acquisition after just two seasons could be deemed counterproductive. That’s putting the cart well before the horse, however, as Texas will face competition from several other clubs in trying to put together the best offer for Olson. Beyond the Yankees, Olson has been reported as a target for the Braves, should Freddie Freeman sign elsewhere. Others yet will view the situation similarly to the Rangers, feeling that while first base isn’t a dire need, Olson himself is so appealing that he’s worth moving some other pieces around to fit into the puzzle.

Rays Expected To Activate Austin Meadows On Friday; Nate Lowe Demoted

By Mark Polishuk | May 9, 2019 at 8:53pm CDT

Outfielder Austin Meadows is expected to be activated from the 10-day IL prior to the Rays’ game with the Yankees on Friday, Marc Topkin of the Tampa Bay Times reports.  Meadows will take the 25-man roster spot left open by Nate Lowe, as the Rays sent the highly-touted youngster down to Triple-A following yesterday’s game.

Meadows hit the injured list on April 21 due to a sprained right thumb, so his return will fall just short of the projected timeline of “a few weeks” mentioned by Rays general manager Erik Neander a day after the IL placement.  It’s good news for the Rays, since Meadows’ hot start was a huge reason for Tampa’s early-season success.  Meadows was hitting .351/.422/.676 with six homers over 83 plate appearances at the time of his injury, and while some regression is inevitable (.400 BABIP, .454 wOBA compared to a .408 xwOBA), it certainly isn’t out of the question that a former top prospect like Meadows could be a big contributors in his first full Major League season.

With Meadows back, Lowe’s first taste of big league action will come to an end after nine games and a .257/.289/.314 slash line over 38 PA.  It was perhaps a little surprising to see Tampa promote Lowe so soon, though the 23-year-old had been ripping up Triple-A pitching and the Rays had a need for another bat with both Meadows and Joey Wendle on the IL.  Rather than keep Lowe in the majors as a bench player, the club will instead send him back to Triple-A where he can everyday at-bats and continue his development.

In terms of service time, Lowe’s clock stopped almost as soon as it started, so it’s hard to yet determine the impact on his future team control.  While it stands to reason Lowe will be back in the majors at some point in 2019, the Rays already control him through at least the 2025 season, and the team might not bring him back until they can ensure that he won’t be a Super Two candidate.  (Of course, this could all be moot if Lowe becomes the latest Rays prospect to sign an early-career extension, a la Brandon Lowe, Matt Moore, or Evan Longoria.)

Lowe has played only first base and DH in his young career, making him an imperfect fit at this point on a Rays roster that values multi-positional versatility.  Lowe’s first base duties will again likely be split between Ji-Man Choi and Yandy Diaz, though Diaz has seen an increasingly amount of time at third base in recent days due to Daniel Robertson’s struggles.  Brandon Lowe could also see some time at first base, with Robertson or Andrew Velazquez filling in at second, so the Rays are hardly short on potential lineup options.

Rays Promote Nate Lowe

By Steve Adams | April 29, 2019 at 11:34am CDT

11:34am: The Rays have announced the promotion, though they’ve yet to reveal the corresponding roster moves. Marc Topkin of the Tampa Bay Times reports (via Twitter) that Christian Arroyo will be optioned to Durham, thus opening a 25-man spot, but there’s still the matter of a 40-man move to be addressed.

11:20am: The Rays are set to promote top first base prospect Nate Lowe to the big leagues, Ken Rosenthal of The Athletic reports (via Twitter). Lowe, who ranks as the game’s No. 90 overall prospect at Baseball America and the No. 3 first base prospect in the game per MLB.com, is not on Tampa Bay’s 40-man roster. A corresponding 40-man move will be necessary.

Nate Lowe | Kim Klement-USA TODAY Sports

While he’s not related to recently extended second baseman Brandon Lowe, Nate Lowe is viewed by the Rays as a similarly vital young piece of the club. The 23-year-old is off to a terrific start with Triple-A Durham, where he has slashed .300/.444/.543 with three homers, eight doubles and nearly as many walks (17) as strikeouts (19) through 90 plate appearances.

MLB.com’s scouting report on Lowe lauds his plus-plus raw power — a trait he was finally able to tap into in game settings a season ago when he raked at a .330/.416/.568 clip across three minor league levels (topping out at Durham). In 2018, Lowe slugged 27 homers, 32 doubles and a triple with a 12.3 percent walk rate against just a 16.2 percent strikeout rate. He’s a below-average runner and limited to first base on the defensive spectrum, but last year’s .313/.395/.484 slash against lefties and .338/.425/.608 slash against righties suggests that he has the potential to be a true everyday option for the Rays at first base and/or designated hitter (as opposed to a platoon slugger).

It’s unlikely that the Rays would call up Lowe if they didn’t feel they had everyday at-bats available to the former 13th-round pick. But, with Ji-Man Choi and Yandy Diaz both performing quite well at first base and designated hitter, neither would appears to be in jeopardy of losing any playing time (barring a yet-unrevealed injury, of course). It’s possible, though, that Diaz could slide across the diamond to third base in place of the struggling Daniel Robertson, opening at-bats at first and DH to be shared among Lowe, Choi and others.

The maximum amount of service time that Lowe would be able to accrue this season is now 155 days, meaning he’ll fall shy of the requisite 172 days to notch a full season. Because of that, he’ll be controllable through the end of the 2025 campaign if he’s in the big leagues for good, and he’s also in line to be a surefire Super Two player after the 2021 season. That said, it’s still possible that he’ll be optioned back to the minors at some point and alter those trajectories.

The Top Minor League Performers Of 2018

By Jason Martinez | September 18, 2018 at 6:15pm CDT

Over at Roster Resource, I rank Minor Leaguers throughout the regular season using a formula that takes into account several statistics with age and level serving as important factors in how they are weighed. These are not prospect rankings!

This is how it works:

  • Hitters are mostly rated by total hits, outs, extra-base hits, walks, strikeouts and stolen bases.
  • Pitchers are mostly rated by strikeouts, walks, earned runs, home runs and hits allowed per inning.
  • A few counting stats are included (IP, plate appearances, runs, RBI) to ensure that the players atop the list played a majority of the season.
  • The younger the player and the higher the level, the more weight each category is given. Therefore, a 19-year-old with an identical stat line as a 25-year-old at the same level will be ranked much higher. If a 23-year-old in Triple-A puts up an identical stat line as a 23-year-old in High-A, the player in Triple-A would be ranked much higher.

A player’s potential does not factor in to where they are ranked. If you’re wondering why a certain prospect who is rated highly by experts isn’t on the list, it’s likely because they missed time due to injury (see Victor Robles or Nick Senzel), MLB promotion (Juan Soto) or just weren’t productive enough. While there are plenty of recognizable names throughout the MiLB Power Rankings Top 200 list, it’s also full of players who were relatively unknown prior to the season and have seen their stock rise significantly due to their performance. Here’s a closer look at the Top 20.

1. Vladimir Guerrero Jr., 3B, Toronto Blue Jays | Blue Jays Depth Chart

Guerrero probably deserved to start his MLB career sometime between the debuts of NL Rookie of the Year candidates Ronald Acuña Jr. (April 25th) and Juan Soto (May 20th). All things being equal, that would’ve been the case.

But his call-up was delayed, mostly because third baseman Josh Donaldson was healthy in May and designated hitter Kendrys Morales was being given every opportunity to break out of an early season slump. As Guerrero’s path to regular playing time was becoming clearer, he suffered a knee injury in early June that kept him out of action for a month. When he returned, the Jays’ playoff chances had dwindled. Instead of adding him to the 40-man roster and starting his service time clock, they chose to delay his MLB debut until 2019.

You can hate the rule, but I’m certain Jays fans would rather have Guerrero under team control in 2025 as opposed to having him on the team for a few meaningless months in 2018 and headed for free agency after the 2024 season. And maybe it’s just me, but I kind of enjoy seeing what kind of numbers a player can put up when he’s way too good for his competition. And all this 19-year-old kid did was slash .381/.437/.636 with 20 HR, 29 2B, 37 BB, 38 K in 408 plate appearances, mostly between Triple-A and Double-A (he had 14 PAs during a rehab stint in the low minors).  Thanks for providing us with that beautiful stat line, Vlad Jr.

2. Kyle Tucker, OF, Houston Astros | Astros Depth Chart

Despite a slow start—he had 21 hits in his first 83 Triple-A at-bats with one homer and 20 strikeouts— the 21-year-old Tucker showed why the World Champions were willing to give him a chance to take their starting left field job and run with it in July.

Tucker wasn’t quite ready for the Big Leagues—he was 8-for-52 in two separate MLB stints prior to a recent third call-up—but his stock hasn’t dropped one bit after slashing .332/.400/.590 with 24 homers, 27 doubles and 20 stolen bases over 465 plate appearances in his first season at the Triple-A level.

3. Luis Rengifo, SS, Los Angeles Angels | Angels Depth Chart

A 21-year-old shortstop just finished a Minor League season with 50 extra-base hits (7 HR, 30 2B, 13 3B), 41 stolen bases, as many walks as strikeouts (75 of each) and a .299/.399/.452 slash line. If the name Luis Rengifo doesn’t ring a bell, you’re probably not alone. He kind of came out of nowhere.

The Mariners traded him to the Rays last August in a deal for Mike Marjama and Ryan Garton. Nine months later, the Rays shipped him to the Angels as the PTBNL in the deal for C.J. Cron. Based on those two trades, I can say without hesitation that the Mariners and Rays did not think Rengifo was this good. Not even close.

4. Nathaniel Lowe, 1B, Tampa Bay Rays | Rays Depth Chart

Lowe’s breakout season mirrors Juan Soto’s in one way: They both posted an OPS above 1.000 at two different levels before a promotion to a third. Soto’s third stop was in Double-A, and it was a very short stint before heading to the Majors. After destroying High-A and Double-A pitching, Lowe’s final stop of 2018 was Triple-A, where he finally cooled off.

Still, the 23-year-old has put himself squarely on the Rays’ radar. After homering just 11 times in his first 757 plate appearances, all in the low minors, Lowe broke out with 27 homers and 32 doubles in 555 plate appearances in 2018. His overall .330/.416/.568 slash was exceptional.

5. Alex Kirilloff, OF, Minnesota Twins | Twins Depth Chart

We’re four seasons into the Byron Buxton and Miguel Sano era—both debuted during the 2015 season—and we can’t say for certain whether either player will even be penciled into the regular lineup in 2019. They could be still turn out to be perennial All-Stars someday. But you can’t blame Twins fans if they temper their expectations for the next great hitting star to come up through their farm system. And yet, that might be difficult with Kirilloff, a first-round draft pick in ’16, and last year’s No. 1 overall pick, Royce Lewis, after the year each of them just had. Both are moving up the ladder quickly.

The 20-year-old Kirilloff, who missed all of last season recovering from Tommy John surgery, was a hitting machine in his first full professional season. After slashing .333/.391/.607 with 13 homers in 65 games with Low-A Cedar Rapids, he hit .362 with seven homers and 24 doubles in 65 games with High-A Fort Myers. He also had 11 hits in the playoffs, including a 5-hit performance on September 5th.

6. Bo Bichette, SS, Toronto Blue Jays | Blue Jays Depth Chart

All Bichette did during his age-20 season was hit 43 doubles and steal 32 bases while manning shortstop for the New Hampshire Fisher Cats, the 2018 Eastern League Champions. It’s unlikely that he’ll join Vlad Jr. in the Majors early next season, but he might not be too far behind.

—

7. Peter Alonso, 1B, New York Mets | Mets Depth Chart

Alonso’s monster season (.975 OPS, 36 HR, 31 2B, 119 RBI between AAA/AA) ended in disappointment when he was passed over for a September promotion. As was the case with Vlad Jr., it didn’t make much sense to start his service time clock and fill a valuable 40-man spot during the offseason—neither Guerrero or Alonso have to be protected from the next Rule 5 draft—while the team is playing meaningless games. The 23-year-old Alonso did establish, however, that he is the Mets’ first baseman of the very near future, and they’ll plan accordingly during the upcoming offseason.

—

8. Touki Toussaint, SP, Atlanta Braves | Braves Depth Chart

As tough as it will be to crack the Braves’ rotation in the coming years, the 22-year-old Toussaint has put himself in position to play a significant role in 2019 after posting a 2.38 ERA and 10.8 K/9 in 24 starts between Triple-A and Double-A. He’s also starting meaningful MLB games down the stretch as the Braves try to seal their first division title since 2013. After spending last October in the Arizona Fall League, where he followed up an underwhelming 2017 season by allowing 10 earned runs in 8 2/3 innings, he could find himself on the Braves’ playoff roster.

—

9. Vidal Brujan, 2B, Tampa Bay Rays | Rays Depth Chart

The highest-ranked player to spend the entire season in Low-A, the 20-year-old Brujan slashed .320/.403/.459 while stealing 55 bases in his first crack at a full season league (27 games in High-A; 95 games in Low-A). He’ll still be overshadowed a bit in a deep Tampa Bay farm system that includes two of the best young prospects in the game, Wander Franco and Jesus Sanchez, but it’s hard to ignore such a rare combination of speed and on-base ability displayed by a switch-hitting middle infielder.

—

10. Michael King, SP, New York Yankees | Yankees Depth Chart

The Yankees’ offseason trade that sent two MLB-ready players, Garrett Cooper and Caleb Smith, to the Marlins cleared a pair of 40-man roster spots prior to the Rule 5 draft and brought back $250K in international bonus pool money. They also received King, who—whether anyone expected it or not—was about to have a breakout season.

After posting a 3.14 ERA with a 6.4 K/9 over 149 innings in Low-A in his age-22 season, numbers that typically indicate “possible future back-of-the-rotation workhorse,”  he looks to be much more than that after his 2018 performance. In 161 1/3 innings across Triple-A, Double-A and High-A, King posted a 1.79 ERA, 0.911 WHIP and 8.5 K/9. He was at his best once he reached Triple-A, posting a 1.15 ERA with only 20 hits and six walks allowed over 39 innings.

—

11. Taylor Widener, SP, Arizona Diamondbacks | Diamondbacks Depth Chart

Unlike the trade to acquire King, the Yankees appear to have gotten the short end of the stick in a three-team, seven-player offseason deal with Arizona and Tampa Bay. They traded away Nick Solak to the Rays and Widener to the Diamondbacks in exchange for Brandon Drury, who was supposed to fill a short-term need for infield depth.

While Drury was a bust in New York—he had nine hits in 51 at-bats before being traded to Toronto in a July deal for J.A. Happ—Solak, a second baseman/outfielder, put up terrific numbers in Double-A (.834 OPS, 19 HR, 21 SB) and Widener has emerged as one of the better pitching prospects in the game. The 23-year-old right-hander posted a 2.75 ERA, 2.8 BB/9 and 11.5 K/9 over 137 1/6 innings with Double-A Jackson.

—

12. Josh Naylor, 1B/OF, San Diego Padres | Padres Depth Chart

The offseason signing of first baseman Eric Hosmer certainly didn’t bode well for Naylor’s future with the Padres. Whether he had an MLB future at all, however, was already in question. First base prospects can’t just be good hitters. They need to mash, which is far from what Naylor did in 2017 (.761 OPS, 10 HR between Double-A and High-A). But a 20-year-old holding his own in Double-A is still interesting, nevertheless. So it was worth paying attention when he hit .379 with seven homers, five doubles, 13 walks and 12 strikeouts in April. He also spent most of his time in left field in 2018, adding a bit of versatility to his game.

Although April was his best month, by far, he still finished with an impressive .297/.383/.447 slash line. He’ll enter 2019 as a 21-year-old in Triple-A who has flashed some power (17 HR, 22 2B in 574 plate appearances) and above-average plate discipline (64 BB, 69 K).

—

13. Eloy Jimenez, OF, Chicago White Sox | White Sox Depth Chart

Unlike the Jays and Mets, who had multiple reasons to keep Guerrero and Alonso in the Minors until 2019, the Sox’s decision to bypass Jimenez for a September call-up was more questionable.

Already on the 40-man roster and without much to prove after slashing .337/.384/.577 with 22 homers and 28 doubles between Triple-A and Double-A, Jimenez’s MLB debut appeared imminent as September approached. But White Sox general manager Rick Hahn, citing Jimenez’s need to improve his defense, confirmed in early September that he would not be called up. Of course, the 21-year-old probably would’ve benefited greatly from playing left field in the Majors for 20-25 games in September. And, of course, Hahn is just doing a good job of not saying the quiet part out loud: Eloy under team control through 2025 > Eloy under team control through 2024.

—

14. Dean Kremer, SP, Baltimore Orioles | Orioles Depth Chart

After posting a 5.18 ERA in 2017, mostly as a relief pitcher in High-A, Kremer’s stock rose quickly with a full-time move to the starting rotation in 2018. In 16 starts for High-A Rancho Cucamonga, the 22-year-old right-hander posted a 3.30 ERA with a 13.0 K/9. After tossing seven shutout innings in his Double-A debut, the Dodgers included him as a key piece in the July trade for Manny Machado. Kremer continued to pitch well with Double-A Bowie (2.58 ERA, 45 1/3 IP, 38 H, 17 BB, 53 K) and now finds himself on track to help a rebuilding Orioles’ team in 2019.

—

15. Nicky Lopez, SS, Kansas City Royals | Royals Depth Chart

Lopez started to turn some heads during last offseason’s Arizona Fall League, and it carried over into 2018 as he slashed .308/.382/.417 with nine homers, 15 stolen bases and more walks (60) than strikeouts (52) between Triple-A and Double-A.  It’s a sign that the 23-year-0ld’s bat is catching up with his stellar defense and that he’s closing in on the Majors, where he could team with Adalberto Mondesi to form one of the better young middle infield duos in the game.

—

16. Royce Lewis, SS, Minnesota Twins | Twins Depth Chart

The No. 1 overall pick in the 2017 draft didn’t disappoint in his first full professional season, posting an .853 OPS, nine homers, 23 doubles and 22 stolen bases in 75 Low-A games before a 2nd half promotion to High-A Fort Myers. He didn’t fare quite as well (.726 OPS, 5 HR, 6 SB in 46 games), but he did hit three homers in the playoffs to help his team win the Florida State League championship. It wouldn’t be a surprise if the if he reached Double-A early next season as a 19-year-old with a jump to the Majors in 2020 not out of the question.

—

17. Michael Kopech, SP, Chicago White Sox | White Sox Depth Chart

Throwing a 100 MPH fastball isn’t as rare as it used to be, but Kopech has reportedly touched 105 MPH, putting him in a class of his own. Unfortunately, the 22-year-old right-hander is expected to join a long list of pitchers who have had their careers interrupted by Tommy John surgery after he was recently diagnosed with a torn UCL.

The timing isn’t great, as Kopech had just arrived in the Majors in late August and would’ve likely been a leading candidate for AL Rookie of the Year in 2019. Still, he’ll only have to prove that he’s back to full health before he returns to the Majors—he should be ready to return early in the 2020 season— after making a strong impression in Triple-A with a 3.70 ERA and 12.1 K/9 in 24 starts.

—

18. Kevin Smith, SS, Toronto Blue Jays | Blue Jays Depth Chart

Not only do Guerrero, Bichette and Cavan Biggio likely form the best trio of infield prospects in the game, two are sons of Hall of Famers—Vladimir Guerrero Sr. and Craig Biggio, and Bichette’s dad, Dante, was also pretty good. And yet, another Blue Jays infield prospect with a very ordinary name and without MLB lineage managed to stand out. The 22-year-old finished the season with 25 homers, 31 doubles, 29 stolen bases and a cumulative .302/.358/.528 batting line between High-A and Low-A.

—

19. Gavin Lux, SS, Los Angeles Dodgers | Dodgers Depth Chart

The former first-round pick wasn’t overly impressive in his first full Minor League season in 2017, slashing .244/.331/.362 with seven homers and 27 stolen bases for Low-A Great Lakes. A move to the hitter-friendly California League in 2018, however, seemed sure to give his offensive numbers a boost. It did. Lux had a .916 OPS and 41 extra-base hits in 404 plate appearances, but he also didn’t slow down once he reached the upper minors late in the year.

In 28 regular season games with Double-A Tulsa, the 20-year-old Lux slashed .324/.408/.495 with four homers in 120 plate appearances. It didn’t end there. Over an eight-game playoff run, the left-handed batter went 14-for-33 with five multi-hit games.

—

20. Patrick Sandoval, SP, Los Angeles Angels | Angels Depth Chart

Acquiring the 21-year-old Sandoval from the Astros for free agent-to-be catcher Martin Maldonado could turn out to be the steal of the trade deadline. While the lefty didn’t stand out in Houston’s deep farm system, he was having a strong season at the High-A and Low-A levels at the time of the trade (2.56 ERA and 9.9 K/9 in 88 innings). The change of scenery didn’t affect him one bit as he tossed 14 2/3 shutout innings in the California League before finishing the season with four impressive Double-A starts (19 2/3 IP, 3 ER, 27 K).
