Philadelphia Phillies starting pitcher Zack Wheeler has been placed on the 15-day injured list due to a blood clot near his right shoulder, with no established timetable for his return. Wheeler underwent a successful thrombolysis procedure to remove the clot from his right upper extremity. Medical experts indicate that such conditions typically require a minimum of three months on blood thinners, during which playing is not permitted, suggesting that Wheeler's season may be over. The Phillies have not provided a definitive recovery timeline. Teammates have expressed concern and support following the diagnosis.
