Madison Bumgarner, who has made three starts without getting a win since coming off the disabled list, starts the opener of a four-game series against the Padres at AT&T Park. It's the second consecutive year the lefty hasn't registered a win in his first three starts; a year ago, he needed seven starts to get his first victory. Tyson Ross starts for the Padres, with first pitch at 7:15 p.m. PT.
