Ace lefty Corbin has Tommy John surgery

SCOTTSDALE, Ariz. -- D-backs left-hander Patrick Corbin underwent Tommy John surgery Tuesday in Pensacola, Fla.

Dr. James Andrews performed the surgery to repair a partial tear of Corbin's ulnar collateral ligament. The recovery time for the surgery is typically 12-18 months, though it varies by player.

"It's a long road back, but I'm sure [Corbin will] do everything he can in his power," D-backs bench coach Alan Trammell said.

Corbin had a breakout year in 2013, going 14-8 with a 3.41 ERA and earning a spot on the National League All-Star team.

The D-backs were counting on Corbin to be their ace this year. He was scheduled to start last Saturday's regular-season opener against the Dodgers, but he sustained the elbow injury March 15 during his final Spring Training start.

D-backs general manager Kevin Towers said last week that the competition to replace Corbin in the rotation was likely down to prospect Archie Bradley and Randall Delgado.

"It's an opportunity for somebody to step up," Trammell said. "And hopefully that happens. Often that's how careers get started. I don't know who that guy is right now, but we'll see."
