A look at D-backs' options with Corbin out

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."

Trammell takes over after Gibson's knee surgery

LAD@ARI: Gibson on Opening Series loss in Australia

SCOTTSDALE, Ariz. -- D-backs manager Kirk Gibson was not at Salt River Fields on Tuesday for the team's light workout, and he may miss Wednesday's Cactus League game as well.

Gibson underwent arthroscopic surgery on his left knee Tuesday. The knee had been giving him problems recently, particularly on the team's recent trip to Australia.

Bench coach Alan Trammell was in charge of Tuesday's workout and will manage the team in Gibson's absence.

Trammell said Gibson told him he would be back Wednesday, but that remains to be seen. Gibson will need to be on crutches for a time, so if he does make it down to the bench for games, it is unlikely he will go to the mound to make pitching changes.

Pollock proposes during trip to Australia

SD@ARI: Pollock belts a two-run triple in the second

SCOTTSDALE, Ariz. -- A.J. Pollock made good use of his free time while the team was in Sydney last week.

The D-backs outfielder proposed to his girlfriend, Kate, while at the Bondi Beach cliff walk.

"She's from Australia," Pollock said. "So I thought this trip was a good time to do it."

The pair met when they were students at the University of Notre Dame, where Pollock played baseball and Kate was a member of the lacrosse team.

D-backs look to get over jet lag after Opening Series

Trumbo and Chavez on playing in Australia

SCOTTSDALE, Ariz. -- The D-backs went through a light workout at Salt River Fields on Tuesday after returning from Australia on Sunday afternoon.

The idea was to get the team moving again and shake off the jet lag before Cactus League games resume Wednesday.

The D-backs lost both regular-season games to the Dodgers, and they now have five more exhibition contests before playing regular-season games again beginning next Monday.

It's natural for there to be a letdown for those games, but that is something the team is trying to avoid.

"They need to fight that and we need to stay as sharp as we can," said D-backs bench coach Alan Trammell, who ran Tuesday's workout in manager Kirk Gibson's absence.

A number of players said Tuesday that they were still suffering from some jet lag.

"I'm pretty tired right now still," catcher Miguel Montero said. "Definitely worse coming back. It's just hard to adjust to the timing, your sleeping. I thought I was fine, because I went to sleep at 9 p.m. or 9:30. I thought, 'This is perfect.' But three hours later, I was wide awake."

"It's normal, it's what we expected," said second baseman Aaron Hill. "It's all right, we'll deal with it."
