DENVER -- Carlos Gonzalez homered twice, including a grand slam, and had a career-high seven RBIs to give the Colorado Rockies a 9-4 victory over the Arizona Diamondbacks on Wednesday night.
Gonzalez had his 15th career multi-homer game, is tied with Nolan Arenado for the team lead with 33 home runs. Arenado also homered as the Rockies earned a split of the four-game series.
Brooks Brown (1-2) pitched 1 1/3 innings and Justin Miller got the final five outs for his first career save.
Trailing 4-3 in seventh, the Rockies loaded the bases with two hits and a walk against Randall Delgado (5-4). Keith Hessler, recalled before the game, came on and Gonzalez hit a 1-1 slider off the facing of the second deck to put Colorado ahead 7-4. It was his fourth career grand slam, second this season.
Gonzalez hit a two-run homer off Matt Stites in the ninth.
Arizona took a 1-0 lead in the first on A.J. Pollock's sacrifice fly, but the Rockies rallied for three in the bottom of the inning. Gonzalez hit a sacrifice fly and Arenado followed with a two-run homer to center, giving him 100 RBIs.
Arenado is the first Colorado player to reach that mark since Troy Tulowitzki had 105 in 2011.
Chris Owings had three hits and drove in two runs for the Diamondbacks. He had an RBI single in the second and a run-scoring double in the sixth that tied the score at 3-all. He scored on a force out later in the inning to give Arizona the lead, but the bullpen couldn't hold it.
