The White Sox designated John Brebbia for assignment Tuesday and recalled righty Prelander Berroa to take his spot in the bullpen.
The Sox also optioned infielder Bryan Ramos to Charlotte after he was with the team for one day and added Jacob Amaya to the active roster.
Amaya was claimed off waivers from the Astros Monday.
Brebbia, 34, is 0-6 with a 6.29 ERA over a team-leading 54 appearances this season, his first with the Sox after signing as a free agent on January 26.
The Sox bullpen leads the majors in blown saves (31), a club-record 42 losses and walks (263). Its 5.10 ERA is the second worst in the majors.
Berroa, 24, is 3-5 with a 6.41 ERA in 43 relief appearances with Charlotte this season. He also has pitched in three games over two stints with the White Sox in 2024, allowing three runs over two innings.
Berroa was acquired from the Mariners on February 3 with outfielder Zach DeLoach and a Competitive Balance B selection (LHP Blake Larson) in the 2024 draft in exchange for right-hander Gregory Santos.
The White Sox 40-man roster is at 39.
