Seranthony Dominguez has signed a two-year, $20 million contract with the Chicago White Sox. According to Passan, Dominguez is expected to be the closer in Chicago.

Fantasy Impact

Dominguez has pitched parts of seven seasons at the big league level, primarily with the Phillies. Dominguez has swing-and-miss stuff as evidenced by his career 27.9% strikeout rate. However, he is prone to command issues at times, having pitched to a 10.5% walk rate. He also uncorked a major league-high 12 wild pitches last season. Dominguez has closing experience with 40 career saves, including a career-high 16 in his rookie season with the Phillies in 2018. All told, the veteran righthander has a 3.50 ERA in 306 career innings and has limited opponents to a .208 batting average. The White Sox have improved their roster this offseason so, if he keeps a hold of the closer's role, Dominguez could easily record 25-30 saves in 2026.

The Baltimore Orioles have traded relief pitcher Seranthony Dominguez to the Toronto Blue Jays in exchange for pitching prospect Juaron Watts-Brown.

Fantasy Impact

The Blue Jays add some much-needed bullpen help in landing Dominguez prior to Thursday's trade deadline. The right-hander owns a 3.24 ERA and a 30.9% K% across 43 appearances this season, locking down two saves in the process.
