ST. LOUIS — The Atlanta Braves activated reliever Manny Acosta from the 15-day disabled list Saturday and optioned right-hander Matt DeSalvo to Triple-A Richmond.

Acosta missed 39 games with a strained left hamstring. The right-hander appeared in 41 games before the injury, going 3-5 with a 4.02 ERA.

DeSalvo returned to the minors after allowing eight runs and six hits Friday in one inning of Atlanta's 18-3 loss to St. Louis. He pitched two innings in a brief stint with the Braves and has a 31.50 ERA.
