Matt Duffy, pinch-hitting for Sergio Romo, broke a 2-2 tie with a two-run single off Diamondbacks closer Addison Reed with one out in the ninth. Crawford doubled home a run in the second inning for his 15th RBI in 15 games, then singled in the fifth and scored on a Gregor Blanco safety squeeze. Bumgarner will get a shot at being the Giants' first 19-game winner in 17 years when he faces the Dodgers in Los Angeles on Tuesday night, but 20 wins would be out of reach if he is replaced in Game 162 and withheld for a playoff start. Chafin responded with his first major-league hit, a shot past first base with two outs in the bottom of the inning that tied the game 1-1 after Bumgarner struggled to throw strikes, walked Cody Ross and fell behind before allowing a Tuffy Gosewisch single. [...] again, Bumgarner could not provide a shutdown inning and allowed the tying run in the bottom of the fifth on a rarely seen play.
