Madison Bumgarner's mere presence back on the mound and healthy after all these months meant so much to the San Francisco Giants, even in defeat. Bumgarner pitched six strong innings yet the Giants missed key scoring opportunities in losing 3-2 to Patrick Corbin and the Arizona Diamondbacks on Tuesday night as San Francisco's five-game winning streak was snapped. ''That's what I get paid to do,'' Bumgarner said.
