Checking In On 2024’s Reliever-To-Rotation Experiments
The 2023-24 offseason saw several teams go outside the box to add to their rotation mix by announcing plans to convert an established reliever into (or back into) a starting pitcher. It’s not a new concept by any means, of course, but it’s always notable when a player who’s found some success in one pitching role is shifted to the other — be it one-inning relievers stretching out to join a rotation or struggling starters shifting to the ‘pen and hoping to find new life as their stuff plays up.
In some instances — e.g. Jordan Hicks, Reynaldo Lopez — the pitchers in question signed lucrative multi-year deals as part of this planned pivot. For others, this role change comes amid their original six seasons of club control and could greatly impact their earnings in arbitration and/or in free agency down the road.
Now that we’re about a quarter of the way through the year, it seems like a good time to check in on how some of these role changes are playing out. Readers should note that this rundown will focus on pitchers who pitched exclusively or near-exclusively out of the bullpen last season. Pitchers like Boston’s Garrett Whitlock (who started 10 games last year and nine in 2022) or Tampa Bay’s Zack Littell (who moved to the rotation last summer and finished out the ’23 campaign as a starter) aren’t the focus here so much as arms who were more strictly confined to short relief recently.
Since so many of these transitions are going to bring about clear workload concerns, we’ll check back in periodically throughout the season. For now, here’s how things are going through about 25% of the schedule.
Jordan Hicks, RHP, Giants
Hicks’ transition from flamethrowing late-inning reliever to … well, flamethrowing starting pitcher has gone seamlessly thus far. It’s only nine starts and 48 innings, but the 28-year-old boasts a 2.44 ERA in his move to the rotation. A career-low 19.9% strikeout rate is a red flag, but Hicks’ 8.2% walk rate is lower than the league average and a career-best mark as well. His 56.2% grounder rate isn’t quite as high as the 60% mark he carried into the season but is still more than 10 percentage points above average.
As one would expect, Hicks’ blazing sinker has lost quite a bit of velocity now that he’s not throwing one max-effort inning at a time. His sinker sat at 100.2 mph last year but is clocking in at 96 mph in 2024. Even with four fewer miles per hour on his primary offering, however, Hicks has more than enough velocity to keep hitters off balance.
Hicks has also fully incorporated the splitter he tinkered with in 2023 into his arsenal this year. After throwing it just 1.6% of the time last season, he’s thrown 22.5% splitters in 2024. Opponents may as well not even bother swinging at the pitch. Hicks has finished off 42 plate appearances with a splitter, and hitters have posted a .079/.167/.105 slash in those instances. Opposing batters have chased the pitch off the plate at more than a 35% clip, and Hicks boasts a huge 42.9% whiff rate on the pitch, per Statcast.
The big question for Hicks, as it is for virtually any pitcher making this transition, is how his arm will hold up once he begins pushing it into uncharted waters. Hicks has never topped 77 2/3 innings in a big league season. That mark came way back in his 2018 rookie showing. The 105 frames Hicks tallied as a minor league starter in 2017 are the most he’s ever pitched in a full season. He’ll be approaching his MLB-high after he makes another four starts or so and will be on the cusp of a new career-high about 10 to 11 starts from now — when there’s still roughly half a season left to play. Hicks wasn’t even especially durable as a reliever, only surpassing 35 appearances in two of his five prior big league seasons. The early returns are outstanding, but the real test will probably come in late June and into July.
Reynaldo Lopez, RHP, Braves
Unlike Hicks, Lopez is no stranger to starting games at the MLB level. He started 73 games for the White Sox from 2018-20 after coming over from the Nationals alongside Lucas Giolito and Dane Dunning in the Adam Eaton trade. The first of those three seasons went well, but Lopez stumbled in 2019-20 and began to transition to the bullpen in 2021.
The shift to a relief role seemed to suit the right-hander well. His already impressive velocity played up even further. Lopez averaged better than 95 mph as a starter in ’18-’20 but saw that number jump to 97.1 mph in 2022 and a massive 98.4 mph in 2023. Over those two seasons, he pitched to a sharp 3.02 earned run average. His rate stats were somewhat uneven, as he showed pristine command (4.3% walk rate) but an only slightly higher-than-average strikeout rate in ’22 before jumping to a huge 29.9% strikeout rate in ’23 … but pairing it with a bloated 12.2% walk rate. Taken together, however, Lopez gave the Sox 131 1/3 innings with that 3.02 ERA, 31 holds, six saves, a 27.4% strikeout rate and an 8.5% walk rate.
When he signed with the Braves for three years and $30MM, that generally fell in line with expectations for what he’d command as a late-inning reliever. However, it quickly became clear that the Braves were going to stretch Lopez back out. There was plenty of skepticism — myself very much included, admittedly — but the experiment has gone better than anyone could’ve imagined.
Thus far, Lopez has not only been the Braves’ best starter but one of the most effective starters in the league. He’s pitched 35 1/3 innings of 1.53 ERA ball. His velocity has dipped back down to his 2018-20 levels, sitting 95.6 mph, but that’s to be expected working out of the rotation. His 25.5% strikeout rate is better than average but not elite. His 9.9% walk rate could stand to come down. But Lopez is throwing more curveballs than ever before (10%), has largely abandoned his changeup and is keeping the ball on the ground at a career-best 41.1% rate. That’s a bit shy of the 42.8% league average but noticeably higher than the 35% clip he posted during his time with the White Sox.
The uptick in grounders is one reason that Lopez is yielding a career-low 0.51 homers per nine innings. The other is a 5.4% homer-to-flyball rate that he almost certainly can’t sustain. That fluky HR/FB and an abnormally high 88.7% strand rate are part of the reason metrics like SIERA (3.87) and xFIP (3.79), which normalize HR/FB, tend to peg him for some regression. Still, even if he’s bound to see his ERA tick up by a couple runs, Lopez has looked great through his first six turns.
Time will tell just how his arm can handle a return to his 2018-19 workloads, but the early results are excellent — and the importance of his breakout is magnified by the loss of ace Spencer Strider to season-ending elbow surgery. Notably, Lopez exited last night’s start with some tightness in his back, but manager Brian Snitker suggested after the game that he’s likely to make his next start.
A.J. Puk, LHP, Marlins
On the other side of the coin, the Marlins’ efforts to move Puk back into a starting role quickly went down in flames. Puk, a former No. 6 overall pick who worked as a starter in the minors, looked excellent this spring. He pitched 13 2/3 innings over four starts and two earned runs with a 23-to-4 K/BB ratio. The transition could hardly have gotten out to a more promising start.
In his first four regular-season starts, Puk also pitched 13 2/3 innings. The similarities stop there. Opponents bludgeoned Puk for 14 earned runs on 19 hits and a stunning 17 walks. He fanned only 12 of his 77 opponents (15.6%).
Miami placed Puk on the injured list on April 20 due to left shoulder fatigue. He returned from the injured list just yesterday. Despite myriad injuries in their rotation, the Fish have already pulled the plug on the rotation experiment for Puk, announcing that he’ll be back in the bullpen following his stay on the injured list. It’s a role he thrived in over the past two seasons, logging a 3.51 ERA, 29.4% strikeout rate and 6.9% walk rate while piling up 22 saves and 19 holds.
If Puk returns to form as a reliever — he was particularly impressive in ’23, striking out 32.2% of opponents against a 5.4% walk rate — the ill-fated rotation gambit will be little more than a footnote in what hopefully ends up as a strong overall career as a reliever. If Puk’s struggles persist, however, there’ll be plenty of second-guessing the decision to take one of the team’s best relief arms and stretch him out despite a litany of injury troubles that had combined to limit Puk to only 147 2/3 innings in his entire career prior to this season.
Garrett Crochet, LHP, White Sox
Crochet has worked to a pedestrian earned run average on the season due to a bevy of home runs allowed, but the former first-rounder who’s drawn comparisons to Chris Sale since being drafted by the White Sox has turned in elite strikeout and walk numbers. The 4.63 ERA looks unimpressive, but Crochet has fanned more than a third of his opponents (34.2%) against a pristine 4.8% walk rate.
Crochet boasts an excellent 14.5% swinging-strike rate and is averaging 96.9 mph on his heater. That’s a ways from the 100.2 mph he averaged in six innings as a rookie in 2020, but Crochet has had Tommy John surgery since that time and is working in longer stints now as opposed to bullpen work in ’20. This year’s velocity actually slightly exceeds his average velocity from working purely as a reliever in 2022-23.
In terms of workload concern, Crochet is up there with Puk in terms of extreme uncertainty. He entered the season with a total of 73 big league innings since his No. 11 overall selection in 2020 and is already at 46 2/3 innings on the young 2024 campaign. So long as he keeps missing bats and limiting walks anywhere near his current levels, the run-prevention numbers will come down — FIP and SIERA peg him at 3.33 and 2.37, respectively — but it’s anyone’s guess as to how Crochet will hold up. He skipped the minor leagues entirely, so even if you add in his whole minor league body of work, that’d only tack last year’s 12 1/3 rehab innings onto his track record. Going from a total of 85 1/3 professional innings over a four-year period to a full starter’s workload is bound to have some bumps in the road, but so far Crochet looks quite intriguing as a starting pitcher.
Jose Soriano, RHP, Angels
The Angels nearly lost Soriano back in 2020, when the Pirates selected him in the Rule 5 Draft. At the time, Soriano was wrapping up his rehab from 2020 Tommy John surgery and could’ve been stashed in a rebuilding Pittsburgh bullpen upon his reinstatement from the injured list. A setback in his recovery early in the season prompted another wave of imaging and revealed a new tear, however. Soriano underwent a second Tommy John surgery on June 16, 2021. He was eventually returned to the Angels.
Unfortunate as that back-to-back pair of surgeries was, Soriano’s injury troubles allowed the Angels to keep him in the system. They’re now reaping the benefits. The flamethrowing righty made 38 relief appearances last season and pitched to a quality 3.64 ERA with a huge 30.3% strikeout rate — albeit against a troubling 12.4% walk rate. Soriano averaged 98.6 mph on his heater last year and wound up picking up 15 holds, as the then-rookie righty increasingly worked his way into higher-leverage spots.
The Angels announced early in spring training that Soriano would be stretched out as a starter. His ramp-up continued into the regular season. His first two appearances this year came out of the bullpen but both spanned three innings. He’s since moved into the rotation and has looked quite impressive. Through his first seven starts, Soriano touts a 3.58 ERA with an above-average 24.8% strikeout rate and an outstanding 62.8% ground-ball rate. Even though he’s working in longer stints, he’s improved his fastball and is now sitting at 99.3 mph with it. His 12.4% walk rate still needs improvement, but the returns here are quite promising.
Soriano only pitched 65 1/3 innings between the minors and big leagues last year, and he’s already at 38 2/3 frames on the 2024 season. He’s never pitched more than 82 1/3 innings in a professional season. We’ll see how he fares as he pushes past those thresholds, but there’s a lot to like with this rotation move — even though it’s garnered far less attention than some of the others around the game.
Tyler Alexander, LHP, Rays
The Rays obviously have a knack for finding hidden gems and converting unheralded arms into viable starting pitchers — hey there, Zack Littell — and Alexander is an example of their latest efforts to do so. The left-hander has started for the Tigers in the past and functioned in a swingman role, but the Rays picked him up in a low-cost move following a DFA in Detroit with the idea of stretching him out. Since it’s Tampa Bay, not all of Alexander’s “starts” have been, well, actual starts. He’s followed an opener on multiple occasions already, but he’s followed that one- or two-inning table-setter with at least four innings each time out.
Overall, Alexander has made eight appearances and averaged just under five frames per outing (39 2/3 total innings). He’s sitting on a pretty rough 5.45 ERA, thanks in part to a six-run drubbing at the hands of the Yankees last time out (though he did at least complete seven frames in that start, helping to spare the Tampa Bay bullpen). Alexander’s 19.1% strikeout rate is about three percentage points shy of average. His 6.9% walk rate is about two points better than average. However, he’s taken his longstanding status as a fly-ball pitcher to new heights in 2024, inducing grounders at just a 30.4% clip.
Alexander’s 14.5% homer-to-flyball ratio is only a couple percentage points north of average, but because of the sheer volume of fly-balls he’s yielding, he’s still averaging more than two taters per nine frames. Opponents have posted an ugly 11.8% barrel rate against him (ugly for Alexander, that is). If he can’t cut back on the fly-balls and/or start finding a way to avoid the barrel more regularly, it’s going to be hard for Alexander to find sustained success. The Rays don’t convert on every dart-throw — much as it’s fun to joke to the contrary — and so far the Alexander experiment hasn’t paid off.
Bryse Wilson, RHP, Brewers
Wilson’s move to the rotation wasn’t necessarily planned, but injuries up and down the Brewers’ staff forced the issue. Five of his past six outings have been starts and he’s sporting an eye-catching 1.78 ERA in that span. The rest of the numbers in that stretch are less impressive. Wilson has a tepid 17.3% strikeout rate in that stretch but has walked an untenable 13.5% of opponents. Opponents have posted a hefty 45.7% hard-hit rate (95 mph or more) against him during that time. Were it not for a .191 BABIP and 92.2% strand rate, the ERA wouldn’t look nearly as rosy. Metrics like FIP (4.64) and SIERA (5.34) are quite bearish.
Wilson is still scheduled to take the ball on Saturday in Houston, but his recent stretch of run-prevention doesn’t seem sustainable without some improvements in his K-BB profile.
Rays Sign Tyler Zuber To Minor League Deal
The Rays have purchased the contract of right-hander Tyler Zuber from the independent Atlantic League’s Long Island Ducks, the Ducks announced yesterday. Zuber will head to Tampa Bay on a minor league contract and is headed to Triple-A Durham.
Zuber, who’ll turn 29 next month, signed a minor league pact with the Guardians in the offseason and spent spring training with them but struggled in his brief look in the Cleveland organization. He served up 10 runs on 10 hits and eight walks in 5 1/3 frames this spring and unsurprisingly didn’t land an Opening Day roster spot. He was released and went on to sign with the Ducks, hoping a strong showing would bring about just this type of opportunity with another club.
Brief as his time with the Ducks was, it’s not hard to see why Zuber’s performance piqued some interest. The former Royals righty pitched just 5 2/3 innings of Atlantic League ball but held opponents to one run on five hits and one walk. He faced a total of 22 opponents and set 10 of them down on strikes (45.4%).
Zuber previously pitched for the Royals in 2020-21, debuting during the pandemic-shortened season with 22 innings of 4.09 ERA ball. He posted a gaudy 30.3% strikeout rate that year but coupled it with an alarming 20.2% walk rate. Overall, he’s pitched 49 1/3 big league innings with a 5.29 ERA, a 24.8% strikeout rate and a 16.7% walk rate.
Command was never an issue for Zuber in the lower minors, however. His overall minor league ERA sits at a tidy 3.20, and he’s paired that with a terrific 31.3% strikeout rate and a solid 8.5% walk rate. Zuber began to battle pronounced control struggles during that 2020 debut, and his penchant for walks carried over into subsequent seasons.
It’s likely that injuries played a part in the abrupt erosion of Zuber’s command. He had shoulder injuries in both 2021 and 2022, missing the entire ’22 season as a result. He was with the D-backs’ Triple-A Reno affiliate in 2023 but still walked 11.1% of his opponents in 20 2/3 innings. Given his recent struggles to locate the ball, Zuber’s impressive command in the Atlantic League is all the more notable, but time will tell whether he can carry that over in his return to affiliated ball.
Cardinals Release Josh James
The Cardinals announced Tuesday that right-handed reliever Josh James has been given his unconditional release. The former Astros reliever had been pitching with their Triple-A affiliate in Memphis after signing a minor league deal in the offseason.
James hasn’t pitched in the big leagues since 2021. The 31-year-old spent the the majority of the 2022 season on the injured list before eventually undergoing flexor surgery that cost him the whole 2023 campaign. He made for an intriguing minor league flier, given some prior success in Houston, but James displayed calamitous command issues during his brief time with the Redbirds. In 7 2/3 innings this season, he’s been shelled for 17 earned runs (19.96 ERA) on 13 hits and 15 walks with only five strikeouts. James faced 51 hitters and walked 15 of them (29.4%).
Before encountering his forearm injury, James spent four seasons in the Houston bullpen as a hard-throwing middle reliever with lofty strikeout and walk totals. In 106 1/3 innings at the MLB level, James has fanned 34.3% of his opponents but also issued walks at a 13.2% clip — all en route to a 4.64 earned run average.
It’s possible he’ll get another look elsewhere, but a near-30% walk rate in Triple-A on the heels of such a lengthy injury layoff underscores that James is a project at this point. He’s quite a ways removed from the impressive 2.35 ERA, 32% strikeout rate and 7.7% walk rate he turned in as a rookie with the 2018 Astros.
Cubs Designate Richard Lovelady For Assignment
The Cubs designated left-hander Richard Lovelady for assignment Tuesday, per a team announcement. His spot on the 40-man roster will go to righty Tyson Miller, whose previously reported trade from Seattle to Chicago is now official.
Lovelady, 28, signed a minor league pact with the Cubs back in January and was selected to the big league roster in late April. He’s tossed 5 2/3 innings out of Craig Counsell’s bullpen and been tagged for five runs on nine hits and a pair of walks with six strikeouts. That marks the fifth big league season in which the southpaw has appeared; Lovelady made his MLB debut with the 2019 Royals and pitched in K.C. from 2019-21, and he logged 23 1/3 innings with the A’s last season. Overall, in 70 2/3 big league innings, he carries a 5.48 ERA but with a far more encouraging 22.7% strikeout rate, 8.8% walk rate and 49.8% ground-ball rate.
That blend of strikeouts, walks and grounders, coupled with a strong Triple-A track record, has made Lovelady appealing to MLB teams over the past year despite a history of success in the majors. The Cubs are his fourth organization since Opening Day 2023. Lovelady has been picked up by the Braves in a small trade, claimed off waivers by the A’s, and quickly selected to the big leagues with the Cubs.
In parts of six Triple-A seasons, Lovelady has a 2.95 ERA with a sharp strikeout, walk and ground-ball rates of 26.6%, 6.8% and 50.7%, respectively. He’s not a power arm, but he has added more than a mile per hour to both his four-seamer and sinker since last year’s showing with Oakland. He sat at 91 mph with both pitches last year but averaged 92.8 mph on the four-seam and 92.5 mph on his two-seam during his brief showing with Chicago.
Lovelady does have a minor league option remaining, so any club that picks him up via trade or waiver claim could send him to Triple-A without first passing him through waivers themselves. He’ll be traded, claimed off waivers or assigned outright to Triple-A Iowa within the next week (if he clears waivers). He’s been outrighted previously in his career, so Lovelady would have the right to reject a minor league assignment from the Cubs if he does go unclaimed.
Cardinals Notes: Matz, Liberatore, Marmol
The Cardinals have been without Steven Matz all month, as the veteran lefty has been on the shelf due to a lower back strain. He’d been slated to throw a bullpen session today, but that’s now been scrapped due to ongoing discomfort, tweets Jeff Jones of the Belleville News-Democrat. Instead, Matz will receive an injection and be shut down from throwing for “at least” the next week — possibly longer, depending on how he responds to the latest treatment.
Matz, 33 at the end of the month, is in the third season of a four-year, $44MM contract signed in free agency. The former Mets and Blue Jays hurler rebounded from a dreadful first season of that agreement in 2022 to give the Cards 105 innings of 3.86 ERA ball last season. He did so with diminished strikeout and walk rates relative to his ’22 levels but also with a resurgent 44.8% grounder rate that helped in mitigating some of the home run troubles he’d experienced in his first year with St. Louis.
The 2024 season has seen Matz make six starts and struggle to a low tally of 27 1/3 innings as well as a grim 6.18 ERA. Matz’s 13.4% strikeout rate would easily be a career-low and stands as the eighth-lowest mark among any of the 182 MLB pitchers to toss at least 20 innings this season. His 8.7% walk rate is average, but this year’s 33.7% ground-ball rate is the lowest of his career other than a 30-inning sample from the shortened 2020 season.
With Matz now sidelined even longer than expected, a window will further open for fellow southpaw Matthew Liberatore. Manager Oli Marmol told the Cardinals beat that plugging Liberatore into Matz’s rotation spot for now “gives us the best chance to win” (X link via Jones), so it seems he’ll remain the preferred option to start in Matz’s absence. Liberatore, acquired from the Rays in the trade sending Randy Arozarena to Tampa Bay, hasn’t topped 50 pitches in an outing this year and thus figures to be limited when he takes the ball today in a road matchup with the Angels. His longest outing of the season has been 3 2/3 innings, but if he can work efficiently, it’s feasible he could get through four or five innings before the Cards go to the bullpen.
Speaking of Marmol, he’s come under quite a bit of fire as the Cardinals have followed up 2023’s surprising last-place finish with an ugly start that once again has them residing in the NL Central’s cellar. Fans have voiced plenty of criticism for the third-year skipper, and president of baseball operations John Mozeliak — who surprisingly fired former manager Mike Shildt and installed Marmol as the new skipper — seemed to choose his words carefully when asked by KMOX’s Tom Ackerman how he currently views his manager (X link with audio).
“These are times that are difficult,” said Mozeliak. “I still think he understands the job. I think he knows how to manage. I think he’s trying to put the right combination of players in, but at some level you’ve got to have some performance. I understand fans are not happy with myself. They’re not happy with Oli. I don’t think anything I say here today is going to change that, so I think we have to just keep trying to go back and try to get this to work. And look, we understand if it doesn’t, then people are going to be held accountable — and ultimately that starts with me.”
Marmol was entering the final season of his original three-year deal to manage the Cardinals this year, but the front office extended him through the 2026 season back in mid-March. That contract seemed a clear vote of confidence at the time, but less than two months later, Mozeliak is publicly noting that his skipper has “got to have some level of performance” and speaking about accountability both on the field level and in the front office.
The 16-24 Cardinals are eight games back of the division-leading Brewers and have the fourth-worst run differential in MLB (-51), leading only the Rockies, Marlins and White Sox. Cardinals hitters rank 28th in the majors in batting average (.220), 27th in on-base percentage (.298) and 29th in slugging percentage (.341). Their 136 runs are the second-fewest in MLB, and St. Louis is tied with the White Sox for the game’s fewest home runs (29).
The revamped rotation hasn’t been much better. Cardinals starters are 24th in the big leagues with a combined 4.49 ERA and rank 22nd with a 20.5% strikeout rate. The bullpen, led by closer Ryan Helsley and setup men JoJo Romero, Ryan Fernandez and Andrew Kittredge, has been better, but it’s a top-heavy group. The struggles of those in the final few spots of the ‘pen have Cardinals relievers sitting at a flat 4.00 ERA on the season, ranking 15th in the big leagues.
Orioles Designate Ryan McKenna For Assignment
The Orioles announced Monday that they’ve designated outfielder Ryan McKenna for assignment. His spot on the roster will go to veteran Austin Hays, who has been reinstated from the 10-day injured list after missing about three weeks with a strained calf. It’s the second bit of outfield shuffling by the O’s today. Baltimore previously optioned Heston Kjerstad to Triple-A Norfolk in favor of Kyle Stowers.
McKenna, 27, was only selected back to the 40-man roster for a second stint with the Orioles on April 26. He appeared in nine games and went 3-for-8 at the plate, popping a pair of home runs in his brief look with the club. Despite that productive cup of coffee, he won’t stick around on the big league roster. McKenna is out of minor league options, so the O’s had little choice but to designate him for assignment once things reached a point where they needed to open his roster spot back up. In all likelihood, McKenna knew it’d be a short stay on the active roster.
A fourth-round selection by the O’s in the 2015 draft, McKenna has now appeared in parts of four seasons with the MLB club. Despite the big showing in this year’s tiny sample, he struggled extensively from 2021-23, hitting just .222/.299/.318 in 508 plate appearances across that three-year span. He owns a productive .261/.359/.561 output in 274 Triple-A plate appearances but also a .234/.327/.357 slash in a much larger sample of 817 Double-A plate appearances.
Baltimore is stacked with outfield talent — and with position players in general — leaving little room for McKenna to wrest everyday at-bats from the team’s other outfield options. Colton Cowser, Cedric Mullins, Anthony Santander and the now-reinstated Hays are all in the mix for at-bats, as is the aforementioned Stowers, who’s joining the club for his 2024 debut after smacking 11 Triple-A homers in his first 165 plate appearances there this season. Mullins has been in a deep slump of late, and Hays struggled a good bit before landing on the injured list himself. However, both veterans have lengthy track records of production that date back several years. Neither was going to be displaced because of a brief hot streak from McKenna.
The Orioles have a week to trade McKenna or else place him on outright waivers or release waivers. He went unclaimed on outright waivers at the end of March, and in doing so gained the right to reject any additional outright assignments for the remainder of his career. As such, if he clears waivers, he’ll have the right to reject a minor league assignment in favor of free agency. Given the glut of outfield talent on the Baltimore roster, it’s possible he’d prefer to latch on with another organization that has far less depth and thus a better opportunity for him to get an earnest look at the big league level.
Orioles Claim Corbin Martin, Recall Kyle Stowers
1:23pm: Baltimore will option top outfield prospect Heston Kjerstad to Norfolk to make room for Stowers, tweets Ghiroli.
12:50pm: The Orioles announced Monday that they’ve claimed right-hander Corbin Martin off waivers from the Brewers. He’s been optioned to Triple-A Norfolk. Baltimore’s 40-man roster had an open spot and is now at capacity. It seems as though this will be just one of multiple moves for Baltimore today, as Britt Ghiroli of The Athletic also reports that the O’s are calling up outfielder Kyle Stowers from Norfolk. The team has yet to announce that move or any corresponding transactions.
Martin, 28, was a second-round pick of the Astros in 2017 who went from Houston to Arizona as one of the headline pieces in 2019’s Zack Greinke blockbuster. His career trajectory has been impacted by injuries — Tommy John surgery most notably. Martin pitched in the big leagues in 2019, 2021 and 2022 but has just 57 2/3 MLB frames under his belt. He’s limped to a 6.71 earned run average in that time, fanning a well below-average 19% of his opponents against a weighty 13.6% walk rate.
Entering that 2019 season in which he was traded, Martin ranked 78th and 81st on the respective top-100 prospect lists published by Baseball America and MLB.com. He was touted as a high-probability mid-rotation arm, having just wrapped up a season that saw him toss 122 innings of 2.51 ERA ball with a 25.5% strikeout rate and 7.3% walk rate between High-A and Double-A. He underwent Tommy John surgery in early July and was included in the aforementioned Greinke trade just weeks later — a deal that was completed and filed just seconds before the deadline. Martin missed the entire 2020 season as a result and hasn’t looked the same in any of his post-surgery seasons.
In parts of three seasons since that ligament reconstruction, Martin has pitched to an ERA north of 6.00 in Triple-A. Hitter-friendly Pacific Coast League caveat notwithstanding, that type of performance simply doesn’t measure up to his prior promise. He was tagged for 21 runs in 16 big league innings with Arizona in 2021, posted a 6.08 ERA in 77 frames with the D-backs in 2022, and missed the entire 2023 season after suffering a torn tendon in his latissimus dorsi during spring training.
More concerning than the poor ERA marks was the evaporation of Martin’s command post-elbow surgery. The 7.3% walk rate he posted in 2018 feels like a distant memory. Martin issued a free pass to 11.4% of his opponents in 2021-22 (MLB and Triple-A combined). He walked a massive 13 of 50 opponents thus far in 2024 (26%).
All of those struggles aside, it’s not entirely surprising to see the Orioles claim Martin. Baltimore general manager Mike Elias was the Astros’ scouting director in 2017 when they selected Martin with the 56th overall pick in the draft and paid him a $1MM signing bonus. Elias is keenly familiar with Martin — both as the pitcher he was shaping up to be prior to his injuries and as a person.
As for Stowers, he’ll return to the big leagues for a third straight season. He hit fairly well in a small sample of 98 plate appearances in 2022 before floundering through a 2-for-30 stretch at the plate in the majors last season. The lefty-swinging 26-year-old is out to a .240/.315/.541 start in Norfolk this season and has already socked 11 home runs in 165 trips to the plate.
Contact remains something of an issue, as Stowers is still punching out in just shy of 27% of his plate appearances against a 7.9% walk rate. Nonetheless, he’ll add some left-handed pop to Baltimore’s outfield mix for the time being. Stowers has spent the bulk of his pro career in right field but has experience in all three spots and has spent more time in center this year (115 innings) than either right field (89) or left field (54).
David Peralta Opts Out Of Cubs Deal
Veteran outfielder David Peralta opted out of a minor league contract with the Cubs and elected free agency, as indicated on the MiLB.com transaction log. He’ll now be an option for any club seeking some left-handed-hitting and/or corner outfield depth.
The 36-year-old Peralta is a former Gold Glove and Silver Slugger winner who’s spent the bulk of his career with the Diamondbacks, for whom he played a pivotal role over the course of nine seasons. From 2014-22, Peralta batted .283/.340/.463 in 961 games and 3728 plate appearances as a member of the D-backs. He belted 110 homers — including a career-high 30 in 2018 alone — and added another 191 doubles and 46 triples for good measure.
By measure of wRC+, Peralta was 12% better at the plate than the average hitter during his Arizona tenure. Couple that with strong overall defensive ratings in the outfield corners, and Peralta was a quietly valuable player for the Snakes for upwards of a decade. The Diamondbacks rewarded his consistency with a three-year, $22MM contract extension heading into the 2020 season, buying out a pair of free-agent seasons in the process.
Arizona wound up trading Peralta to Tampa Bay prior to the 2022 trade deadline, and he’s had subsequent struggles both with the Rays and (in 2023) with the Dodgers. Since leaving Phoenix, Peralta has batted .258/.301/.368 in 602 big league plate appearances.
Peralta inked his minor league deal with the Cubs back in February. As Maddie Lee of the Chicago Sun-Times wrote last month, he wasn’t immediately ready for game action, as he was still wrapping up the rehab process from an October procedure to repair the flexor tendon in his left forearm back in October. Peralta got into six games late in spring, going 8-for-18 with a homer, a double and triple, but he opened the season in extended spring training as he wasn’t yet fully cleared to throw from the outfield. He wrapped up a rehab/throwing program and joined the Cubs’ Iowa affiliate on April 11.
In 20 games and 85 plate appearances with Iowa, Peralta has posted a .217/.341/.348 batting line. He’s been dinged by a .232 average on balls in play that’s more than 100 points shy of his career .326 mark in the majors, which has surely played a role in the pedestrian offensive rate stats he’s produced. Peralta’s approach and plate discipline seemingly remain quite sound; he’s walked at a 14.1% clip against just a 15.3% strikeout rate.
Peralta has notable platoon splits in his career, with a .289/.343/.474 slash against righties in his big league career against a .241/.303/.361 line versus fellow lefties. Speculatively speaking, a team with multiple injuries and/or struggles in the outfield (e.g. Giants, Royals, Cardinals) could make some sense for Peralta on another minor league deal, as he’ll likely prioritize signing somewhere with a relatively clear path to a big league opportunity.
Sean Burroughs Passes Away
Former big league infielder Sean Burroughs passed away this week at just 43 years of age, Bob Nightengale of USA Today reports. Tragically, the former Little League World Series hero and No. 9 overall draft pick collapsed while coaching his son’s little league game.
The son of former No. 1 overall draft pick, two-time All-Star, and 1974 American League MVP Jeff Burroughs, Sean clearly had baseball in his DNA. He starred on the mound and at the plate while leading his Long Beach team to consecutive Little League World Series wins and eventually went on to be selected by the Padres with the ninth overall pick in the 1998 draft. Baseball America ranked him among the sport’s top-100 prospects in each of the next four years, including top-10 rankings each year from 2000-02. Burroughs represented the United States in the 2000 Summer Olympics in Sydney and won a Gold Medal.
Burroughs made his big league debut as the Padres’ third baseman on April 2, 2002 — collecting two hits in his first taste of MLB action. He struggled through the season’s first two months but returned from a Triple-A assignment to hit .377/.433/.410 in 67 September plate appearances. Burroughs was the Padres’ regular third baseman in 2003-04, hitting a combined .292/.350/.384 in 1142 trips to the plate. He struggled at the plate again in 2005 and was traded to the Devil Rays in a 2005-06 offseason deal that sent right-hander Dewon Brazelton back to the Friars.
Burroughs appeared in only eight games for the Rays plus another 37 with their Triple-A affiliate in Durham. He was out of baseball entirely for several years after that and had since candidly spoken about a subsequent spiral of drug addiction and alcoholism. In a heart-wrenching interview with ESPN’s Jim Caple in 2011, Burroughs described the harrowing experience of spending years living in cheap Las Vegas motels, eating out of trash cans and abusing virtually any substance he could find. “I would just try to fill myself with as much substances as I could, legally or illegally,” he acknowledged.
Despite that low point — which Burroughs likened to the Nicolas Cage film Leaving Las Vegas — Burroughs’ baseball career had a second act. He cleaned his life up, got a second chance from late D-backs GM Kevin Towers (who’d drafted Burroughs with the Padres), and played in 78 games with the 2011 Diamondbacks. Burroughs inked a minor league deal with the Twins that offseason and wound up appearing in ten games with Minnesota as well. Those would prove to be the final games of his MLB career, but he spent the 2014-17 seasons playing between several teams in the independent Atlantic League, as well as in Venezuelan Winter ball and in the Mexican League.
Burroughs’ big league career lasted all of 528 games and saw him bat .278/.335/.355. Despite that modest performance, he’ll be remembered as a remarkable talent — one who was thrust into a national spotlight at an early age and racked up more accolades than most players accrue in a lifetime before he even set foot on a major league field. His tragic passing will bring about immeasurable “what ifs,” but Burroughs also stands as a beacon of perseverance. Overcoming his yearslong battle with addiction to return to the major leagues and spend more than a half decade in pro ball is inspirational in and of itself — the type of story that transcends baseball and has the power to impact a far broader audience.
We at MLBTR offer our condolence to the Burroughs family and to his friends, former teammates and coaches, and countless fans around the world.
Willson Contreras Expected To Miss About 10 Weeks
Cardinals catcher Willson Contreras underwent surgery to stabilize the fracture in his forearm on Wednesday of this week. Manager Oli Marmol tells the Cardinals beat that the surgery went as expected, and Contreras is expected to miss around 10 weeks of action. He’s hopeful of returning shortly before the All-Star break (via John Denton of MLB.com and Katie Woo of The Athletic on X). Contreras suffered the fracture this week when Mets designated hitter J.D. Martinez struck his left forearm during a swing.
Subtracting Contreras from an already struggling Cardinals lineup is a gut-punch. Veteran stars Paul Goldschmidt and Nolan Arenado have both underperformed this season (the former, in particular), while injuries have kept Tommy Edman off the field entirely and limited Lars Nootbaar‘s time on the field (and arguably his productivity as well).
The Cards are batting just .217/.296/.339 as a team. They rank 29th in the majors in home runs (27), 29th in runs (127), 28th in batting average, 27th in on-base percentage and are tied with the Marlins for 27th in slugging percentage. As longtime Cardinals reporter and St. Louis radio host Bernie Miklasz points out on X, the trio of Goldschmidt, Nolan Gorman and Dylan Carlson have astonishingly combined to go 0-for-48 since the calendar flipped to May.
Were it not for an eye-popping start to the season from Contreras, those team totals and rankings would be far worse. He’s been far and away the team’s best hitter, batting .280/.398/.551 with six homers in 128 plate appearances. Contreras’ six homers lead the club, and he’s also pacing the team in doubles (11), walks (18) and wRC+ (171).
In his absence, the Cardinals will turn catching duties over to the tandem of Ivan Herrera and Pedro Pages. Herrera has long been a touted catching prospect who looked ready for an audition as a big league regular, but between iron man Yadier Molina and the team’s signing of Contreras, that opportunity hadn’t presented itself — until now. The 23-year-old is out to a slow start in 76 plate appearances this year, hitting just .232/.276/.377. However, he slashed .297/.409/.351 in 13 games with the Cards last year in addition to posting a huge .297/.451/.500 line (147 wRC+) in 83 Triple-A contests (375 plate appearances).
Pages made his big league debut this month. He’s appeared in six games but has just eight plate appearances and has yet to log his first major league hit. The 2019 sixth-round pick is considered a glove-first catching prospect but did post a quality .267/.362/.443 slash (142 wRC+) in 497 Double-A plate appearances last season. He was 4-for-18 with a homer and two doubles in Triple-A prior to his call to the big leagues.
The 15-22 Cardinals have lost five straight games and eight of their last ten. Their -41 run differential ranks 25th in the majors and 12th in the National League.
