The White Sox activated all four of their trade deadline additions while making several notable decisions at catcher, in the bullpen and in the outfield.
After acquiring four players ahead of MLB’s trade deadline, the Chicago White Sox made several roster moves on Tuesday to finalize their active 26-man roster before this week’s series against the Boston Red Sox at Fenway Park.
Chicago activated all four of its new additions, including catcher Joey Bart, right-handed pitchers Luis Castillo and Huascar Brazoban, and outfielder Brenton Doyle.
The White Sox only needed to clear two additional roster spots because two players on the MLB roster departed in their deadline trades. Catcher Edgar Quero and left-handed pitcher Tyler Schweitzer have both been optioned to Triple-A Charlotte.
Quero was replaced by Bart, whom the White Sox acquired from the Atlanta Braves just hours before the trade deadline. Bart figures to take on the lion’s share of the catching responsibilities for the White Sox moving forward, with Drew Romo serving as the backup.
Why did the White Sox move on from Quero instead of Romo? It is the same reason they have done so in the past: to give Quero an opportunity to receive regular at-bats in the minor leagues and continue developing after what has been a really rough 2026 season.
The defense is also a real factor here. While the two have been relatively interchangeable offensively (and not in a good way), Romo has produced a -0.1 fWAR in 2026, while Quero sits all the way down at -0.7 fWAR. That's because Romo has been slightly above average as a blocker and framer, while Quero has proven to be one of the worst defensive catchers in the league.
If nothing else, the White Sox get average defense from Romo. As they look to tread water while waiting for Kyle Teel’s return, that is better than continuing to send out Quero, who has recently been a hindrance in almost every aspect of the game.
Schweitzer was optioned to Triple-A Charlotte and is effectively being replaced in the bullpen by Erick Fedde. With the addition of Castillo, the White Sox announced that Fedde would move from the starting rotation to the bullpen. He will likely serve as a multi-inning reliever capable of handling mop-up duty when the rest of the pitching staff is tired.
Schweitzer has performed that job very well up to this point, but Fedde should also be a solid option while bringing steady veteran leadership and the ability to make a spot start when needed.
The other notable roster decision comes in the outfield, with the White Sox activating Doyle. Chicago is choosing its new addition over Austin Hays, who remains in Triple-A Charlotte on a rehab assignment. Hays is healthy and appears ready to return, but even after designating Everson Pereira for assignment, the White Sox do not seem inclined to bring him back to the active roster.
Activating Doyle certainly improves Chicago’s overall defense. But the White Sox no longer have much offense to turn to off the bench. Against right-handed pitching, their reserves include Luisangel Acuña (.550 OPS), Brenton Doyle (.569 OPS) and Drew Romo (.504 OPS), with Randal Grichuk serving as the only semi-reliable bench bat.
We could see several players make their White Sox debuts on Tuesday night when Chicago takes on the Boston Red Sox at Fenway Park. Left-hander Patrick Sandoval will take the mound for Boston against White Sox right-hander Davis Martin.
