Mejia (0-2) was tagged with the loss Monday against Atlanta after allowing six runs on eight hits and two walks across four innings, striking out four.
Mejia was recalled from Triple-A Reno to make his third start of the season but was far from effective, allowing season-worst marks in both hits and runs while also tossing his shortest outing of the campaign. He's made just three starts this season and the results haven't been there; Mejia has allowed 12 earned runs and posted a 14:5 K:BB across 15 innings.
