Manager Fredi Gonzalez said he's not worried about Beachy.
"He had a little sore [elbow] going, and we didn't want to take a [chance]," Gonzalez said. "He's fine."
Beachy has been the Braves' best starter this season. He leads the Major Leagues with a 1.98 ERA and has a 0.99 WHIP. After two solid months, Beachy said he's not opposed to receiving some extra rest.
"Can't hurt," Beachy said. "I want to be out there as often as I can, but I'm not going to complain about getting a couple extra days of rest."
Beachy is scheduled to throw another bullpen session on Wednesday.
