LOS ANGELES -- Madison Bumgarner pitched two-hit ball over eight innings, giving the San Francisco Giants a 3-0 win against the Dodgers while overshadowing the major league debut of high-priced Los Angeles pitcher Hyun-Jin Ryu on Tuesday night. Bumgarner (1-0) struck out six and walked none in the second straight gem at Dodger Stadium. The only hits were a pair of doubles by Andre Ethier and A.J. Ellis. Left-hander Clayton Kershaw homered and pitched a four-hit shutout in the Dodgers' 4-0 victory on Opening Day on Monday.
