What Happened

Luis Castillo, acquired by the White Sox at the trade deadline, made a significant impact in his second start for the team. Pitching against the Reds on Wednesday at Rate Field, Castillo threw seven scoreless innings, allowing only one hit and two walks over 104 pitches. He recorded a season-high 10 strikeouts, a performance that manager Will Venable described as "outstanding" and catcher Drew Romo called "dog.". This outing marked the first time this season Castillo had pitched more than six scoreless innings, and his strikeout total was his highest since the final start of the 2025 season.

Why It Matters

Castillo's dominant performance suggests the White Sox may have acquired a valuable rotation piece. The team holds contractual control over Castillo through the 2027 season. His effective pitching contributes to the White Sox's current standing in the American League Central, where they improved to 62-57 and hold a lead over several other teams.

Background

The White Sox acquired Castillo at the trade deadline in exchange for reliever Seranthony Domínguez and minor league players Boston Smith and Nolan Jones. The team identified changes they wanted Castillo to make, specifically encouraging him to utilize his changeup more frequently. In his previous starts with the White Sox, Castillo had been leaning more on his slider, a strategy that had been an organizational priority for his former team, the Mariners. This adjustment appears to have paid off in his recent outing.
