The Braves recalled pitcher Williams Perez from Triple-A Gwinnett and optioned pitcher Michael Kohn to the same team.
Perez has made five starts with Gwinnett, going 2-0 with a 1.33 ERA and 21:9 K:BB ratio in 27 innings. He has yet to pitch in a major-league game in the regular season.
Kohn has made six appearances with the Braves without giving up a run or a hit, but he has walked six batters while striking out four.
