Braves right-hander Chris Resop began a rehabilitation assignment in Double-A Mississippi on Saturday.
Resop, on the disabled list with a left oblique strain, started the game against Mobile and was scheduled to pitch at least two innings.
The Braves placed Resop on the 15-day disabled list on June 16, one day after suffering the injury in his first appearance of the season. He was injured in a game against the Rays where he gave up five runs on five hits and three walks in a two-inning relief appearance.
Resop went 5-2 with a 1.84 ERA in 13 starts for Triple-A Gwinnett before being re-called to the majors when the team faced a deadline to put him on the major league roster, trade him or allow other teams a window to sign him.
