Madison Bumgarner is all for his bat starting rallies that help the San Francisco Giants win. Bumgarner pitched into the seventh to snap a two-start skid and also batted in an AL ballpark, and the Giants avoided a four-game sweep by beating the Oakland Athletics 12-6 on Thursday night. Buster Posey hit a towering three-run homer to center in the third and Brandon Crawford followed with a solo shot before adding an RBI single two innings later.
