White Sox sign pitcher Seranthony Domínguez to free agent deal

The Chicago White Sox have agreed to a free-agent deal with pitcher Seranthony Domínguez, the team announced Thursday.

According to the White Sox, the deal will pay Domínguez $20 million over two seasons, and includes a mutual option for the 2028 season.

To make room for Domínguez on the 40-man roster, the White Sox have designated Bryan Ramos for assignment.

The 31-year-old Domínguez spent the 2025 season with the Baltimore Orioles and Toronto Blue Jays, totaling 67 appearances between the two clubs. He posted a 4-4 record and a 3.16 ERA in those appearances, with 79 strikeouts and 36 walks.

Domínguez made a big impact on the World Series for the Blue Jays, pitching five times and allowing just two hits and one earned run in those appearances.

Now, Domínguez will be a key contributor to a White Sox bullpen that has also added Sean Newcomb during the offseason, and he’ll be hoping to lead the team forward after back-to-back tough seasons on the South Side.

Pitchers and catchers report to spring training for the White Sox in coming days, with their first workout set for February 10.
