Marsh will start in the Royals' regular-season finale against Atlanta on Sunday, Anne Rogers of MLB.com reports.
Marsh shifted to the Royals' bullpen after Michael Lorenzen (lower body) returned from the 15-day injured list Wednesday. However, with the Royals clinching a playoff spot Friday, Marsh will start in the regular-season finale, presumably to open the door for Cole Ragans to start in Kansas City's opening game of the AL Wild Card Series. Across 25 outings (24 starts) this season, Marsh has an 8-9 record with a 4.65 ERA, 1.27 WHIP and 121:39 K:BB across 124 innings.
