Chicago White Sox

Luis Castillo

SP

Castillo posted a 7.52 ERA in six starts and then a 13.50 ERA in three relief outings after being demoted to the Chicago bullpen. The veteran right-hander will be eligible for activation during the ALDS, but considering how he's pitched, there's a good chance Castillo's season is over even if he's healthy.

Prelander Berroa

RP

Berroa has been on the injured list all season while working his way back from Tommy John surgery and a setback he suffered while pitching in the Arizona Complex League. He was cleared to resume throwing in early July, and although his progress has been slow, the White Sox haven't ruled out a return for the 26-year-old before the end of the season.

Ky Bush

SP

Bush has spent the entire season on the 60-day injured list while recovering from Tommy John surgery that he underwent in February. He was cleared to resume throwing in early July, but he has since suffered a setback that will keep him on the shelf for the rest of the 2026 season. Bush will turn his focus toward being fully healthy for the start of the 2027 campaign.

Jordan Leasure

RP

Leasure will miss the remainder of this season and likely all of next season while on the mend. Fegan notes that the right-hander hopes to be ready for spring of 2028. Leasure landed on the injured list in late May with a right flexor strain, and while he had been cleared to resume throwing side sessions at the beginning of August, it was ultimately determined that he needed to go under the knife to repair his UCL.

Joey Bart

C

Bart's hand was hit by a pitch during Thursday's game against Boston. The veteran catcher is set to be sidelined until at least mid-September, and how he progresses in his recovery program will determine whether he'll be back in action with the White Sox before the conclusion of the 2026 season. With Kyle Teel also sidelined until at least September due to a left high-ankle sprain, Drew Romo and Edgar Quero will handle catching duties for the White Sox moving forward.

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.

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.
