Though their latest winning streak has ended, the San Francisco Giants have a chance to cap an extremely successful month on a positive note. Trying to do his part, Madison Bumgarner can continue his own May success by winning a fourth straight start Sunday against the visiting Atlanta Braves. Despite falling 8-0 on Saturday, San Francisco (30-21) has won a major league-leading 21 of 29 games this month and can conclude its most successful month in 61 years with a victory in the finale.
