ARLINGTON, Texas -- Athletics left-hander Dallas Braden needs shoulder surgery.
Braden, who pitched a perfect game against Tampa Bay in May 2010, will have surgery Monday in New York to repair a torn capsule in his left shoulder.
"It's a tough day. He's such a competitor and good kid, you hate to see him miss time," manager Bob Geren said after Wednesday's postponed game in Texas. "But you just hope for the best for him in his procedure and recovery. He means a lot to the team and we miss him."
Braden (1-1, 3.00 ERA) was put on the 15-day disabled list April 17, a day after he pitched five scoreless innings at Detroit but left early with a stiff left shoulder. The decision for surgery came after Braden met this week with specialists in Florida and New York.
The A's said Braden's recovery time will be determined after the operation by Dr. David Altchek, medical director of the New York Mets.
"I hope he recovers and gets healthy. Hurry up and join us as soon as possible," fellow left-hander Gio Gonzalez said after getting a fortunate break.
Gonzalez gave up a grand slam as part of a seven-run inning by the Texas Rangers, who led 7-0 in the middle of the fourth Wednesday before heavy rains. Since the game was postponed before becoming official, none of the stats -- including the worst inning of his career -- will count.
"It's a bittersweet moment. It doesn't matter about the game anymore," Gonzalez said. "Dallas is more important than this game."
Before Wednesday's game, the A's recalled right-hander Trystan Magnuson from Triple-A Sacramento and sent left-hander Jerry Blevins outright to that minor league team.
Blevins had allowed at least one run in six of his last eight appearances and was tied for second among AL relievers with 12 walks.
"Magnuson was throwing the ball extremely well down there, great reports, and he's replacing a guy that was struggling," Geren said. "He's a big kid who throws hard, is talented and is eager to learn."
Geren said injured closer Andrew Bailey, on the DL since spring training with a strained right forearm, will pitch in an extended spring training game Saturday. The right-hander will throw one inning or 20 pitches.
