Perez (shoulder) was moved to the 60-day DL, Kevin McAlpin of the Braves Radio Network reports.
The team has yet to indicate if this latest move is due to Perez having a setback in his rehab as well as when he's expected to return to action. While Perez recovers, Atlanta will likely continue to start miscellaneous pitchers in his place, as they've already used 14 starters this season.
