There's nothing really "good" about Zack Wheeler's surgery news that Philadelphia Phillies fans learned of over the weekend. But with Wheeler going under the knife for thoracic outlet decompression surgery in the near future, fans need to know exactly what Wheeler is dealing with.
He has venous thoracic outlet syndrome (vTOS), which sounds horrible, and is. The only good thing about Wheeler's syndrome and pending surgery is that it has a better long-term outlook, per MLB.com's Paul Casella, than the procedure for neurogenic TOS (nTOS), the version of the syndrome that affects the nerve and that has destroyed many MLB pitchers' careers.
