O'Flaherty (back) began a rehab assignment over the weekend, Grant McAuley of 92.9 The Game reports.

EDGE Analysis

O'Flaherty has been sidelined since May 20, but he seems to be nearing a return to the Braves' bullpen. His initial outing with Triple-A Gwinnett was scoreless, although he'll need to improve upon his 6.59 ERA in the big leagues if he wants to garner any fantasy value.
