Phillies Pitcher Zack Wheeler Out 6-8 Months After VTOS Surgery

Philadelphia Phillies ace Zack Wheeler will miss the remainder of the 2025 season after undergoing thoracic outlet decompression surgery to address venous thoracic outlet syndrome, a condition caused by a blood clot in his right shoulder. The surgery, which follows a prior procedure to remove the clot, has a recovery timeline of six to eight months, putting Wheeler's availability for the 2026 season opener in doubt. Wheeler's recent performance showed signs of decline, but he has been one of the National League's top pitchers this season with a 10-5 record and a 2.71 ERA. While this surgery has sidelined other pitchers permanently or diminished their effectiveness, there is precedent for successful comebacks, such as Merrill Kelly's post-surgery career. Phillies officials have emphasized Wheeler's health and full recovery as the priority, acknowledging the uncertainty regarding his future pitching performance. This development significantly impacts Philadelphia's pitching rotation as they pursue the NL East title.
