Bailey undergoes Tommy John surgery

CHICAGO -- Reds starter Homer Bailey had successful Tommy John surgery Friday to repair a torn ulnar collateral ligament in his right elbow. Bailey's recovery time is expected to be nine to 12 months.

Reds medical director Dr. Tim Kremchek performed the operation on Bailey, who suffered a complete tear of the ligament.

"[Kremchek] said … the flexor mass was still intact. It looked strong," Reds general manager Walt Jocketty said.

In September, Bailey had surgery to repair a torn flexor mass tendon near the same elbow.

Bailey, 28, was 0-1 with a 5.56 ERA in his two starts following his activation from the 15-day disabled list on April 18 upon a full recovery from his previous surgery. He is in the second year of a six-year, $105 million contract.

Also having successful Tommy John surgery on Friday was Triple-A Louisville pitcher Matt Magill, who completely tore his UCL on one pitch during a game Wednesday. Magill was acquired in the December trade with the Dodgers for outfielder Chris Heisey.

"I was there. He came off the mound and we weren't sure what it was," Jocketty said.

"Both surgeries went as well as he expected. Both came out very good."
