what happened to zach wheeler

Zack Wheeler, the ace pitcher for the Philadelphia Phillies, was diagnosed with venous thoracic outlet syndrome in August 2025 after a blood clot was found near his right shoulder. He underwent surgery to remove the clot and then was recommended to have thoracic outlet decompression surgery, which typically requires 6 to 8 months of recovery. As a result, Wheeler missed the remainder of the 2025 MLB season, including the postseason. Despite the setback, he has expressed determination to return in 2026 and continue pitching at a high level. He also made a public appearance supporting his team during the 2025 postseason, receiving a standing ovation from fans.
