OAKLAND, Calif. -- Athletics right-hander A.J. Griffin has undergone elbow ligament replacement surgery, becoming the second Oakland starter lost to the season-ending procedure this year.
The A's say Griffin had the surgery Wednesday morning in Houston after receiving a second opinion on his sore arm Tuesday from Dr. Thomas Mehlhoff. The doctor also operated on Oakland pitcher Fernando Rodriguez last year.
Teammate Jarrod Parker underwent the same surgery before the season.
The 26-year-old Griffin was 14-10 with a 3.83 ERA last season after making his major league debut in 2012, when he went 7-1 with a 3.06 ERA in 15 starts for the A's.
Griffin had begun the season on the disabled list with the hope of returning from his injury after rest, but never got far enough to resume a throwing program.
