Muller allowed three runs on two hits, two walks and a hit batter while striking out three in 4.2 innings versus Washington on Friday. He did not factor in the decision.

In addition to the hit batter, Muller also threw three wild pitches in a game where he didn't have the sharpest control. He was spared the loss when Atlanta rallied in the bottom of the fifth inning. The southpaw has given up more than two runs in only two of his eight big-league appearances (seven starts) this year. He owns a 2.88 ERA, 1.11 WHIP and 36:17 K:BB across 34.1 innings. Muller lines up for his next start versus Cincinnati next week.
