White Sox acquire Luis Castillo from Mariners in four-player deal
Chicago received right-hander Luis Castillo from Seattle in exchange for outfielder Nolan Jones, reliever Seranthony Domínguez and prospect Boston Smith, assuming Castillo’s remaining contract.
The Chicago White Sox completed a trade with the Seattle Mariners that sends outfielder Nolan Jones, right-handed reliever Seranthony Domínguez and catcher/outfielder prospect Boston Smith to Seattle. In return, Chicago receives right-handed starter Luis Castillo and agrees to take on his contract, which pays $22.75 million for the next two seasons with an option for 2028.
The Mariners acquire the three players as part of a broader effort to reshape their rotation, which has also been linked to potential moves involving pitchers Emerson Hancock and George Kirby before the trade deadline.
Castillo, 33, posted a 5.06 ERA and a 1.39 WHIP over 99 2/3 innings this season. He will join a Chicago staff that exceeded expectations this year and is positioned for a postseason run.
Seattle’s front office indicated that the trade aligns with its strategy to develop top prospect Kade Anderson and consider additional roster adjustments as the season progresses.
