Perez is expected to start Wednesday against the Phillies, David O'Brien of the Atlanta Journal-Constitution reports.
The Braves and Angels have worked out a deal for Jhoulys Chacin, who was slated to start Wednesday opposite Jerad Eickhoff. Chacin will be replaced by Perez, who tossed a complete-game one-hitter with seven strikeouts in his last start for Triple-A Gwinnett. The 24-year-old Perez failed to make it out of the fifth inning in any of his three starts for Atlanta last month, allowing seven total runs with an unsightly 6:8 K:BB in 12.1 innings.
