Dr. James Andrews performed the procedure in Gulf Breeze, Fla., replacing Beachy's ulnar collateral ligament.
"It's tough," general manager Frank Wren told mlb.com. "He was really doing everything that you can ask, and growing as a pitcher and growing in stature as a guy you could count on to shut the other team down. So it's tough to lose him, and it's obviously tough for him."
Beachy was tied with R.A. Dickey with a 2.00 ERA for the Major League lead. He went 5-5 in 13 starts and held opponents to a .171 batting average, also best in the bigs.
The Braves gave Beachy three extra days off after he originally experienced elbow discomfort on June 8, figuring it was bone spurs. In his last outing on Saturday, however, Beachy was forced to leave with pain in his elbow after just 3 1/3 innings.Tags: Atlanta, Atlanta Braves, Brandon Beachy, Dr. James Andrews, MLB
