PHILADELPHIA — Dave Dombrowski breathed a sigh of relief when he found out the more particular diagnosis for his ace, Zack Wheeler. The veteran executive has had a few of his pitchers deal with thoracic outlet syndrome, and he’s seen the condition sabotage careers. But when Dombrowski heard that the blood clot near Wheeler’s shoulder that was discovered this summer was caused by venous thoracic outlet syndrome and not neurogenic thoracic outlet syndrome, Philadelphia’s president of baseball operations was encouraged.
No person wants to develop a blood clot, and no pitcher wants to have TOS.
