Arizona will start Joe Saunders (0-3, 5.67 ERA). Saunders has struggled this season, most recently giving up three runs, six hits and three walks in six innings against the Colorado Rockies on Tuesday. He will have to eliminate his recent poor play today in order to give the Diamondbacks a shot at the series win.
The Padres will start Aaron Harang (4-2, 4.37 ERA). After winning his first four starts this year, Harang has dropped his last two. Looking to rebound and recapture his early season success, Harang will try to get his first win against the Diamondbacks in nearly eight years today.
