Chicago White Sox

Kyle Teel

C

Teel progressed to running the bases this weekend, which was the final step of his rehab program before being cleared for game action. The 24-year-old has been sidelined two months by the hamstring strain, so he'll likely need at least a handful of games in the minors to get up to speed before being activated by the White Sox.

Austin Hays

LF

Hays landed on the injured list Monday with a strained left calf, and running the bases will likely be one of the final hurdles he has to clear. It remains unknown whether the White Sox will send him out on a rehab assignment before activating him, but an updated timeline for his return may come out after he begins running.

Mike Vasil

RP

The move clears a spot on the 40-man roster for outfielder Dustin Harris, who was called up from Triple-A Charlotte. Vasil underwent Tommy John surgery in March and will be sidelined until around the middle of the 2027 season.

Tanner Murray

LF

The move opens up a spot on the 40-man roster for Randal Grichuk, who signed a one-year major-league deal with the White Sox on Monday. Murray suffered a left shoulder dislocation and fracture while making a diving catch in left field against the Nationals in late April. His recovery timeline was initially set at 4-to-6 months, which means he won't be available to return until at least late August.

Mason Adams

RP

Adams, 25, would have had a chance to reach the majors in 2025 if he was healthy, but now he's likely to out until at least midseason of 2026. He posted a 2.92 ERA and 110:28 K:BB over 120.1 innings between Double-A Birmingham and Triple-A Charlotte in 2024.

Tim Elko

1B

The 26-year-old hit the opening market in November after Chicago elected not to tender him a contract for 2026, but he's now back with the organization on a minor-league deal. Elko underwent surgery to repair a torn ACL in his right knee after the season, so he'll be unavailable for at least the first few months of the 2026 campaign.

Brooks Baldwin

LF

The transaction is merely a formality, as Baldwin is already slated to miss the rest of the season after undergoing internal brace surgery on his right elbow last Wednesday. The utility player will cede his spot on the White Sox's 40-man roster to left-hander Tyler Schweitzer, who was called up from Triple-A Charlotte.

Ky Bush

SP

Chicago made the transaction prior to the start of spring training, when the team needed to open up a spot on the 40-man roster. On the mend from February 2025 Tommy John surgery, Bush was able to throw multiple bullpen sessions during spring training, but it's unclear when he'll be ready to face hitters, according to MLB.com. He'll be shelved for at least the first two months of the season while he works his way through the rehab process.

Everson Pereira

RF

Pereira was labeled day-to-day after he exited Tuesday's 5-2 win over the Angels due to an injury that the White Sox initially referred to as a sore right shoulder, but follow-up tests revealed the pec strain. The White Sox are still in the process of evaluating Pereira and haven't offered up a clear timeline for his return, but he'll be out for at least the next week and a half after hitting the IL for the second time this season. The White Sox called up Jarred Kelenic from Triple-A Charlotte in a corresponding move to replenish their depth in the outfield, but Austin Hays could end up serving as Pereira's primary replacement in the starting nine.

Prelander Berroa

RP

The move makes room on the White Sox's 40-man roster for right-hander Osvaldo Bido, who was claimed off waivers Saturday from Atlanta. Berroa continues to recover from Tommy John surgery that he underwent in March of 2025. By being moved to the 60-day IL, the earliest he can make his 2026 regular-season debut is late May.

Drew Thorpe

SP

Thorpe was transferred to the 60-day injured list Tuesday, but that's not an indication of the progress in his recovery from Tommy John surgery. It's unclear when he may begin a rehab assignment, but that will likely be the next step.
