Megill was recalled from Triple-A Iowa on Monday, Tony Andracki of Marquee Sports Network reports.
Megill made three relief appearances with the Triple-A club after he was sent down in mid-June, and he allowed a run on four hits and a walk while striking out three in three innings. The right-hander will now rejoin the major-league bullpen as a low-leverage reliever after Tommy Nance was sent down Monday.
