Mey will be up with the Reds for the third time this season after posting a 7.27 ERA, 1.96 WHIP and 14:10 K:BB in 8.2 innings over seven appearances between his prior two stints in the big leagues. He'll likely be ticketed for a low-leverage role out of the bullpen.

Mey was recalled from Louisville on Tuesday and got into one game with the Reds, allowing two runs on three walks, a hit batsman and one hit over one-third of an inning versus St. Louis on Friday. He'll now return to the minors in order to clear a spot on the 26-man roster for Rhett Lowder (shoulder), who was activated from the injured list in a corresponding move.
