Phillies ace right-hander Zack Wheeler is out for the rest of the season, the team announced Saturday. Wheeler, 35, has been diagnosed with venous thoracic outlet syndrome (TOS), and the recommendation was to undergo thoracic outlet decompression surgery in the coming weeks. Such a procedure typically has a recovery time of six to eight months.

Philadelphia Phillies executive Dave Dombrowski broke his silence about the franchise pitcher's future after a brutal health update.

Wheeler was diagnosed with venous thoracic outlet syndrome, and will undergo surgery after having a blood clot removed in his right arm. The expected recovery time is six to eight months.
