Zack Wheeler’s season took a sharp turn when a blood clot near his throwing shoulder landed him on the 15-day injured list, forcing the Phillies to rethink rotation plans. Early indicators point to a cautious approach with treatment already underway, including blood thinners, as doctors determine whether surgery to decompress the area (likely the first rib) is needed. If surgery is required, Wheeler’s 2024 campaign would end, but a return in 2025 remains plausible. The Phillies will prioritize long-term health as they map a careful path forward.
