White Sox Transfer Martin Perez To 60-Day IL, Select Bobby Dalbec

The White Sox selected the contract of infielder Bobby Dalbec from Triple-A Charlotte, per a team announcement. Fellow infielder Chase Meidroth heads to the 10-day injured list due to inflammation in his right thumb, while veteran lefty Martin Perez is moving from the 15-day IL to the 60-day IL. Perez exited his most recent start due to forearm soreness and was placed on the 15-day injured list over the weekend due to inflammation in his left elbow.

The Sox haven’t provided further word on Perez’s injury, but the move to the 60-day IL was not expected based on the information that’s been made publicly available. A move to the 60-day IL takes him out until at least late June. That’s a tough blow for the ChiSox, both because Perez has had a nice start to the season and because it clouds his potential outlook as a trade candidate prior to July’s deadline.

Perez, 34, signed a one-year deal worth $5MM over the winter. Through his first three starts with the South Siders, he posted a 1.59 ERA with a 26.9% strikeout rate and 13.4% walk rate in 17 frames. History tells us that Perez is highly unlikely to keep inducing strikeouts at that level but also that his walk rate should be expected to drop substantially; over the past four seasons, Perez fanned just 18.4% of his opponents but also limited his walk rate to a solid 8% mark.

However, Perez was roughed up for four runs in three innings against the Red Sox his last time out. He yielded five hits, including a homer, walked two batters and didn’t record a strikeout. There was no major velocity drop, but Statcast did measure Perez’s cutter at a season-low 84.9 mph on average, down from his 85.5 mph average in his first start. His sinker had a similar dip. That’s not stark enough to prompt major concern, but it’s of some mild note in the wake of his 60-day placement. Presumably, White Sox skipper Will Venable will have more information on Perez’s status prior to today’s series finale at Fenway Park.

Fenway was long the home park for Dalbec, 29. The former Red Sox fourth-rounder (2016) ranked among the team’s best prospects for much of his minor league tenure and posted a solid .243/.308/.511 batting line with 33 home runs through his first 545 major league plate appearances from 2020-21. It’s been a sharp decline ever since. Dating back to the 2022 season, Dalbec has appeared in 175 big league games and tallied 499 plate appearances, but he has just a .198/.269/.330 slash to show for it. He’s fanned in 38% of his plate appearances along the way and nearly 37% of his overall plate appearances in the majors.

Through his first 12 games in Triple-A this season, Dalbec has been on a tear. He’s hitting .326/.354/.696 with four homers, three doubles, a triple and a stolen base in only 48 trips to the plate. He’s still punched out in exactly one-third of those turns at the dish, but he’s stinging the ball when he makes contact.

It seems likely to be a short-term stint on the 40-man roster for Dalbec. He’s out of minor league options, so he can’t be sent back down without first being designated for assignment and passed through waivers.

Meidroth tells MLB.com’s Scott Merkin that x-rays on his thumb were negative. He first felt the issue in Charlotte, prior to his original promotion to the majors. He rested a few days and returned to the Triple-A lineup pain-free. It’s resurfaced recently, and after trying to play through it for the past week or so, he’ll now sit down for a longer spell to try to get the issue cleared up once and for all.

Acquired from the Red Sox in the Garrett Crochet trade, the 23-year-old Meidroth was Boston’s 2022 fourth-round pick. He opened the year with a .267/.450/.600 slash through 40 Triple-A plate appearances before being summoned for his MLB debut, and he’s batted .269/.387/.269 in his first 31 trips to the plate as a big leaguer.
