ANAHEIM -- Angels left-hander Tyler Skaggs underwent successful Tommy John surgery on Wednesday, manager Mike Scioscia said.
On Sunday, the Angels announced that Skaggs, 23, would miss the rest of this season and all of next season. Skaggs last pitched July 31 in Baltimore, where he threw 4 2/3 innings of no-hit ball before exiting.
Tommy John surgery typically sidelines a pitcher for 12-18 months, but the Angels said they wouldn't rush Skaggs back to be able to pitch next season.
"The protocol for rehabbing Tommy John surgery is pretty specific, and it's plainly laid out and it's going to be, it'll be a process," Scioscia said. "Like we talked about the last couple of days, it's probably one of the more predictable surgeries as far as an outcome as you could have. We'll just look to see Tyler sometime in the spring of 2016."
Skaggs was 5-5 with a 4.30 ERA in 18 starts for the Angels, who were relying on him to be the club's No. 4 starting pitcher. Instead, the Angels will bank on Matt Shoemaker (10-4, 3.89 ERA) and Hector Santiago (3-7, 3.59 ERA) to continue their recent success.
