White Sox Make Deadline Roster Moves

The Chicago White Sox used the final two days before the 2026 MLB trade deadline to add four players to their major league roster, reshaping both the pitching staff and the bench for the stretch run. The club acquired right-hander Luis Castillo from Seattle on August 2, then added right-hander Huascar Brazobán, center fielder Brenton Doyle and catcher Joey Bart on August 3, according to the team’s transaction log and MLB.com reports. The moves were followed by immediate roster changes. Chicago activated Castillo and Brazobán, activated Doyle and Bart on August 4, optioned catcher Edgar Quero to Triple-A Charlotte, and designated Everson Pereira and Duncan Davitt for assignment, the White Sox transaction page shows. Chris Getz, the White Sox general manager, said the club set out to add major league help without emptying the top of its farm system. “Couldn’t be more excited with what we were able to accomplish,” Getz said after the August 3 deals, according to MLB.com. (mlb.com) ### Which players did the White Sox actually add? Luis Castillo, 33, was the biggest addition. (mlb.com) The White Sox acquired the veteran right-hander from the Mariners for reliever Seranthony Domínguez, minor league catcher Boston Smith, minor league outfielder Nolan Jones and cash, MLB.com and the team transaction page said. Castillo was 3-9 with a 5.06 ERA over 99 2/3 innings in 20 games for Seattle this season, including 17 starts. (mlb.com) Huascar Brazobán arrived from the Mets for right-handers Gabe Davis and Zach Franklin. Brenton Doyle came from the Rockies for right-hander Mason Adams and shortstop Carlos Vielma. Joey Bart came from the Braves for Davitt after Chicago designated the right-hander for assignment. ### How did the deadline change the White Sox pitching staff? (mlb.com) Castillo’s addition changed the rotation picture immediately. MLB.com reported that manager Will Venable shifted Erick Fedde to the bullpen after the trade, while Fedde said he was ready to adapt to the new role. “All right, let’s do it,” Fedde said, according to MLB.com. (mlb.com) Getz said the White Sox targeted innings and experience when they traded for Castillo. “We’re at the bottom of the league in regards to starting pitching innings,” Getz said on an August 2 Zoom call, according to MLB.com, adding that Castillo could help “lead this young pitching staff.” Brazobán gave Chicago another bullpen arm on August 3. (mlb.com) The White Sox activated him the same day they completed the trade, signaling that the move was made for immediate use rather than depth only. ### Why were Doyle and Bart part of the package? Brenton Doyle gave Chicago a right-handed outfield option with defensive credentials and club control. The 28-year-old center fielder won Gold Gloves in 2023 and 2024, and he is not eligible for free agency until 2030, according to MLB.com. (mlb.com) Doyle had hit .214 with one home run and five RBIs in 45 games for Colorado after returning from injuries. (mlb.com) Joey Bart addressed catching depth after Kyle Teel went on the injured list in July. Bart joined Drew Romo behind the plate, and Quero was sent to Charlotte once the deal was completed, MLB.com reported. ### What did the White Sox give up to make the deals? Mason Adams was the most prominent prospect moved in the August 3 trades. MLB.com listed the right-hander as Chicago’s No. 8 prospect at the time of the Doyle deal, while Getz said the club avoided moving its Top 100 prospects. (mlb.com) Getz said other teams pushed for more from Chicago’s system. “We have a lot of players who were asked for from our prospect group,” he said, according to MLB.com, but added that some asks “didn’t make sense” for the White Sox. (mlb.com) ### What happens next after the deadline flurry? Boston was the next stop for the reworked roster. MLB.com said Castillo was set to join the team at Fenway Park and make his White Sox debut in the series finale there on Thursday, August 6, while Doyle and Bart were activated on August 4 as Chicago moved into the next series with its deadline additions in place.
