Marsh did not factor into the decision in Monday's 8-5 win over the White Sox, allowing two runs on six hits and one walk over 4.2 innings. He struck out three.
Marsh entered this outing with a 7.80 ERA across 15 innings in July and failed to get out of the fifth against a feeble White Sox lineup. The Royals right-hander lasted just 69 pitches before being relieved as Chicago had knocked five singles and one double off the 26-year-old. After pitching to a 3.76 ERA in 55 innings over his first 10 starts, he has produced a 5.82 ERA across 46.1 innings since June 8. Marsh may not have a spot in the rotation any longer as Kansas City acquired Michael Lorenzen on Monday and have not announced the rotation plans for the upcoming weekend series in Detroit.
