The White Sox have leaned on openers and bulk relievers throughout 2026, including in the postseason. Grant Taylor has emerged as the team's most valuable arm, posting a 2.25 ERA over 84 innings with 10 saves and a 31.5% strikeout rate. Trade deadline acquisition Luis Castillo is expected back in 2027 after landing on the IL late in the regular season. Pending free agents Erick Fedde and Sean Newcomb are unlikely to return, leaving a young core of Taylor, Burke, Martin, Sandlin, and Schultz.
