Philadelphia Phillies starter Roy Halladay will undergo surgery on his ailing right shoulder to repair bone spurs, a partially torn rotator cuff and frayed labrum.

It is not yet known when he will have the procedure.

The announcement was made Wednesday after the two-time Cy Young Award winner met with Dr. Lewis Yocum in Los Angeles.

There is no timetable for Halladay's return, but he believes he'll pitch again this year.

Over seven outings this season, Halladay, who turns 36 next week, is 2-4 with an 8.65 ERA.
