Mariners Trade Luis Castillo to White Sox for Three Players

The Seattle Mariners have finalized a trade sending pitcher Luis Castillo to the Chicago White Sox for three players: Seranthony Domínguez, Nolan Jones, and Boston Smith, as reported by a league source.

Castillo, who joined the Mariners from Cincinnati in a 2022 trade, has had a mixed performance over the past seasons, holding a record of 36-29 with a 3.50 ERA. However, his recent form has been less impressive, with struggles noted during the ALCS last fall and a challenging current season.

Domínguez has been traded for the third consecutive year and has performed well for the White Sox this season, while Jones has been traded multiple times and is looking to regain form. Smith, a promising young player, has shown strong potential in his first professional season.
