Hernandez (thumb) will start Monday's game against the Marlins, Anne Rogers of MLB.com reports.
Hernandez exited Friday's game after a callus on his thumb opened up, but he'll return to the mound Monday in Miami to serve as Kansas City's opener. The 26-year-old has a 4.76 ERA across 28.1 innings this season and should cover a frame or two before giving way to bulk pitcher Mike Mayers.
