Perez will be given the start Tuesday against Washington, David O'Brien of the Atlanta Journal Constitution reports.
After returning from the 60-day DL on Friday with a rotator cuff strain, it was originally assumed that Perez would only contribute out of the bullpen during the remainder of the season. However, the Braves decided to give Mike Foltynewicz an extra day of rest, allowing Perez to step in. It seems unlikely for Perez to join the rotation, but a strong performance Tuesday could prove otherwise. He compiled an ERA of 4.62 and a 1.21 WHIP during his first nine starts of the season before suffering the shoulder injury.
