Zack Wheeler's Return from Thoracic Outlet Surgery Remains Uncertain

Zack Wheeler, diagnosed with venous thoracic outlet syndrome and a shoulder blood clot last August, underwent surgery in September with an initial 8-month recovery timeline. He has begun throwing from 75 feet, and the Philadelphia Phillies indicate he could be available 'near the start of the season,' a window spanning Opening Day to late May. Wheeler recently spoke publicly, confirming he is progressing well. However, his return from TOS surgery is notoriously challenging, leading to caution regarding his fantasy value.
