Chacin fouled a ball off his left foot before singling to center during his third-inning at-bat. He continued in the game through six innings, but it was after that incident that the D-backs had their most success.
"I was fine," Chacin said. "The foot was sore, but it was nothing that made me pitch bad. I was trying to keep my sinker down, but couldn't do it. Hopefully, tomorrow it's going to be better, But right now it's fine."
The Padres refused to go quietly, though, as they scored a run in the sixth and then four in the seventh thanks to a three-run homer from Wil Myers off Silvino Bracho. Still not done, they added another in the eighth on an Austin Hedges homer.
Fernando Rodney closed out the win in the ninth to pick up his sixth save.
MOMENTS THAT MATTERED Escape artist: Trailing, 1-0, the Padres had a chance to get on the board in the third inning after Chacin and Manuel Margot each singled with one out. Greinke managed to strike out Myers before Yangervis Solarte legged out an infield hit to load the bases. Greinke got Hunter Renfroe to ground to third to end the threat. More >
Oh so close: With two outs in the fifth, Greinke hit a blooper to the gap in right-center. Renfroe made a long run from his spot in right and tried to make what would have been an outstanding backhanded diving catch. The ball ticked off his glove, though, and Greinke reached base. A.J. Pollock then walked and David Peralta singled to load the bases for Owings, who unloaded them with a game-changing homer.
"There were just great at-bats to even get to me," Owings said. "Greinke with the nice two-out knock there, A.J. threw a good at-bat together and then Peralta lined that ball to left. So just to get up in that inning was awesome."
