ATLANTA — The Atlanta Braves have called up pitcher Chris Resop from Triple-A Gwinnett and sent down struggling reliever Jesse Chavez.

Resop was starting at Gwinnett, where he was 5-2 with a 1.84 ERA in 13 appearances. He'll work out of the bullpen for the Braves, taking over the long reliever role from Chavez.

Acquired from Tampa Bay over the winter, Chavez made the Braves despite a miserable spring. He continued to have problems during the regular season, going 0-1 with a 7.33 ERA in 18 games.

On a more positive note, Braves starter Jair Jurrjens threw 66 pitches in a rehab assignment for Gwinnett on Monday. On the DL with an injured hamstring since April 29, he'll likely make two more starts in the minors before rejoining Atlanta's rotation.
