The Chicago White Sox have agreed to a free-agent deal with pitcher Seranthony Domínguez, the team announced on Thursday. The contract will pay Domínguez $20 million over two seasons and includes a mutual option for the 2028 season.

Why it matters

The addition of Domínguez bolsters the White Sox bullpen as the team looks to bounce back from back-to-back tough seasons. Domínguez had a strong 2025 campaign split between the Baltimore Orioles and Toronto Blue Jays, and his postseason performance with the Blue Jays further showcased his value.

The details

To make room for Domínguez on the 40-man roster, the White Sox have designated Bryan Ramos for assignment. The 31-year-old Domínguez posted a 4-4 record and a 3.16 ERA in 67 appearances between the Orioles and Blue Jays last season, with 79 strikeouts and 36 walks. He was particularly effective in the playoffs for the Blue Jays, pitching five times and allowing just two hits and one earned run.
