Perez will start Monday's game in Miami, Mark Bowman of MLB.com reports.
Perez has been terrific while bouncing back and forth between the rotation and bullpen this season, collecting a 2.31 ERA, 0.97 WHIP and 26:11 K:BB over 35 innings covering five starts and three relief outings. The veteran lefty may be in line for just a spot start Monday as Atlanta keeps his role flexible. However, Perez is an option to grab JR Ritchie's spot at some point if the rookie isn't able to rein in his recent control problems.
