Mahle gave up six earned runs in 8.2 innings during the month of May.

After a strong start to his rookie season, Mahle has seen his numbers swell and he now sits with a 4.02 ERA and 1.60 WHIP on the season. Opponents have put together a .276/.391/.379 line against Mahle, with much of that damage coming from his lack of control, as he's walked nine batters in just 15.2 innings. However, because four of the seven runs he's allowed came in just a 4.1-inning span, the Angels will likely be patient with Mahle and see if he can recover before sending him back down to Triple-A Salt Lake.
