The Angels placed Wilson on the 15-day disabled list on Friday with left elbow inflammation. On Saturday, the team announced that Wilson's MRI results show “left elbow impingement secondary to arthritis.”
Wilson also told reporters that an MRI he had earlier this season showed bone spurs in his elbow. He has been pitching with the bone spurs since April, and said he needs surgery now because his range of motion has diminished and he is at an increased risk of shoulder injury.
There is no timetable for Wilson's return. He told reporters he will be able to pitch effectively next year after undergoing surgery.
Wilson, 34, is 8–8 this season with a 3.89 ERA and 1.242 WHIP in 21 starts. He has not made less than 31 starts in a season since moving out of the bullpen while with the Texas Rangers in 2010.
The Angels (55–47) play the Los Angeles Dodgers on the road on Saturday.
