The Braves activated catcher A.J. Pierzynski and right-hander reliever Chris Withrow from the 15-day disabled list on Thursday, the first day of expanded rosters for Major League Baseball.

Pierzynski went on the DL Aug. 17 with a strained left hamstring. He was hitting .218 with a .305 on-base percentage in 113 games played while splitting time with Tyler Flowers. Pierzynski, 39, is in the final season of his contract.

Withrow went on the DL Aug. 8 with elbow inflammation. He had a 3.31 ERA over 32 2/3 innings with 25 strikeouts and 14 walks. Withrow, 27, had Tommy John elbow surgery in 2014 and didn’t pitch in 2015 while recovering.
