Philadelphia Phillies right-hander Roy Halladay will undergo arthroscopic surgery on his right shoulder and is uncertain whether he will be able to pitch again this season.
The surgery will be performed by Dr. Lewis Yocum in Los Angeles to repair a bone spur in his throwing shoulder. Halladay is currently on the 15-day disabled list while battling inflammation.
"They're going to go in and clean up the bone spur, clean up the rotator cuff and the labrum, try and keep that as unevasive as possible," Halladay said before a game against the San Francisco Giants. "From what I understand, if they go in and see during surgery what they saw on the exams, I have a chance to come back and pitch this year. I have a good chance to come back and pitch this year, hopefully be a lot more effective."
Hallaway, 35, is 2-4 with an 8.65 ERA in seven starts this season.
"They said my range of motion will be better, my location will be better, hopefully the velocity will be better," Halladay said.
