Bumgarner rematches with Oakland

The Giants have won four of the last five games started by Madison Bumgarner, who received the assignment for Saturday's Interleague rematch at Oakland. According to Baseball Info Solutions, Bumgarner has had no trouble settling on a favorite off-speed pitch this season. Opponents are 2-for-39 (.051) in at-bats that have ended with his curveball. Bumgarner will oppose right-hander Trevor Cahill, who owns an 11-4 Interleague record.
