Phillies ace Zack Wheeler has been diagnosed with venous thoracic outlet syndrome following surgery to remove a blood clot near his shoulder, ending his 2025 season as he faces 6-8 months of recovery after thoracic outlet decompression surgery. Despite losing Wheeler, who posted a 2.71 ERA this season, the Phillies have a strong rotation to rely on, including Cristopher Sanchez and Aaron Nola, while they consider offseason plans based on his recovery progress.
