A’s vs. Giants lineups: Madison Bumgarner starts in Bay Bridge Series

The A's and Giants renew their annual Bay Bridge Series on Saturday night as the two rivals square off at the Oakland Coliseum for the first game of a two-game series. Oakland and San Francisco split two games last week at Oracle Park, with Madison Bumgarner and Homer Bailey each coming away with a victory. Bumgarner takes the hill again for the Giants on Saturday.
