Mike Vasil to Miss 2026 Season Following Tommy John Surgery

White Sox right-hander Mike Vasil will miss the entire 2026 season after being diagnosed with an elbow injury requiring Tommy John surgery, to be performed by Dr. Keith Meister. Vasil, a key 2025 bullpen contributor with a 2.50 ERA, suffered arm soreness during a March 14 spring start. His absence creates a 40-man roster opening, with candidates like Hagen Smith, Ben Peoples, and Shane Murphy emerging as potential replacements to fill the vacancy in the Chicago pitching staff.
