White Sox acquire Luis Castillo in deadline deal

August 2, 2026 - 01:24

The Chicago White Sox made the first major splash of the trade deadline, acquiring starting pitcher Luis Castillo from the Cincinnati Reds. The move signals a clear intent to win the American League Central this season, as the club looks to bolster a rotation that has been solid but lacking a true frontline arm.

Castillo, a two-time All-Star, brings a power fastball and a devastating changeup that has made him one of the more consistent starters in the National League over the past few years. He immediately slots into the top of the Chicago rotation, giving the team a legitimate ace to lean on in a potential playoff series. The White Sox have been searching for that kind of presence since the start of the season, and they finally got their man.

In exchange, the Reds receive a package of young players, headlined by a couple of highly regarded prospects. It is a steep price, but the White Sox front office has made it clear that the time to win is now. With a division lead that has been shrinking in recent weeks, this deal is a direct response to the pressure mounting on the South Side. Castillo is under team control for another year, so this is not just a rental. The team expects him to be a cornerstone of the pitching staff for the foreseeable future.
