Mike Mikolas was hammered in a losing effort against the Athletics on Sunday, surrendering seven runs on seven hits over his 4 2/3 innings. Mikolas also issued four free passes while walking one. The A's jumped on him with a five-run outburst in the second inning then chased him after adding on another pair in the fifth. He now owns a horrifying 8.54 ERA, 1.67 WHIP and 16/9 K/BB ratio over 26 1/3 innings on the year. If he continues to struggle, he may not sustain his spot in the Rangers rotation.
