PHOENIX -- The A's are hitting the reset button with their starting rotation after learning Monday that probable opening day starter Jarrod Parker will undergo Tommy John-style ligament replacement surgery on his right elbow and miss the 2014 season.
Coming on top of this weekend's news that starter A.J. Griffin needs three weeks of rest on his right elbow before he can contemplate throwing again, the Oakland rotation has been derailed two weeks before the March 31 season opener.
And if that wasn't enough, lefty starter Scott Kazmir was scratched Monday because of triceps stiffness, though he's expected to pitch again in a couple days.
"This is a guy who meant a lot to us," manager Bob Melvin said of Parker after Oakland's 6-2 Cactus League win over the Chicago Cubs. "We'll have to do something else. This is one that we have to get past and move on.
"Everybody in the clubhouse feels bad. This was kind of a down day for us. As a team we have to move on, but we all feel bad for him. We feel we have the depth in the organization to move on."
It's the second time since 2009 that Parker will have Dr. James Andrews perform the surgery. There is a relatively small sample size to determine the success rate of pitchers who have had multiple Tommy John operations, but it's becoming more frequent.
"Unfortunately, there is more data on this than there was four years ago," A's assistant general manager David Forst said. "In the last week, (the subject) has come up a number of times. It's hard to predict right now. You don't know the recovery rate on guys with a second Tommy John."
According to some medical estimates, the success rate for a first surgery is 90 percent; after a second surgery the number drops to 60 percent.
Former A's reliever Jason Isringhausen had the surgery three times and came back to pitch each time. Talking about the multiple surgeries with the Washington Post in 2012, Isringhausen laid out the path ahead of Parker.
