Patrick Corbin (5-6) snapped a two-start losing streak. He allowed three runs on eight hits over 5 2/3 innings. Padres starter Clayton Richard (4-7) allowed four runs in five innings this time around after having held the D-backs to just one run in a complete-game effort against them last month.
MOMENTS THAT MATTERED
Bunt and a belt: Richard retired the first two hitters of the fifth when Gregor Blanco beat out a bunt hit. That brought up Iannetta, who was hitting in the No. 2 spot in the lineup to start a game for just the third time, and he smoked a 2-0 offering over the wall in left to erase the one-run deficit and give the D-backs a 4-3 lead.
