Kelly steps in to replace Rodriguez vs. Reds

Following a day off -- which happens to begin a stretch of six of seven Thursdays when the club will be idle -- the Giants open a three-game series at Cincinnati on Friday at 4:10 p.m. PT. San Francisco will start Casey Kelly as a replacement for NL Rookie of the Year candidate Dereck Rodriguez (6-1, 2.25 ERA), who was placed on the 10-day DL with a hamstring strain he suffered during Tuesday's altercation with the Dodgers. Right-hander Anthony DeSclafani (6-3, 4.46) starts for the Reds.
