The Braves optioned Allard to Triple-A Gwinnett on Sunday.
Allard rejoined the Braves last week but made just one appearance during his latest stint with the big club, giving up three runs on four hits and a walk over an inning of relief Friday against the Rockies. He'll presumably rejoin the Gwinnett rotation with the Braves reinstating Sam Freeman (shoulder) from the 10-day disabled list in a corresponding move.
