Philadelphia Phillies pitcher Zack Wheeler will miss the remainder of the 2025 MLB season after being diagnosed with venous thoracic outlet syndrome. The team announced that Wheeler has undergone venous thoracic outlet decompression surgery and is expected to be sidelined for six to eight months. The condition, which involved a blood clot in his shoulder and compression of a nearby vein caused by large scalene muscles, required two surgeries to address. This injury could potentially impact Wheeler's availability for Spring Training 2026. Additionally, other MLB players have been sidelined recently, including New York Mets right-handed pitcher Frankie Montas, who is out for the season, Milwaukee Brewers All-Star closer Trevor Megill, placed on the injured list with a flexor strain, and Chicago White Sox center fielder Luis Robert Jr., who was placed on the 10-day injured list with a hamstring strain.
