While San Francisco Giants starter Madison Bumgarner will be on the mound Tuesday to face the Los Angeles Dodgers, his usual foil - Clayton Kershaw - is not quite ready to make it a duel of aces. Kershaw did not start for the Dodgers on Opening Day last week for the first time since 2010 because of shoulder inflammation, but he will pitch Thursday for Triple-A Oklahoma City in a rehab outing. On Tuesday at Dodger Stadium, Los Angeles will send left-hander Hyun-Jin Ryu back to the mound for his second outing.
