DENVER -- In a back-and-forth game, the surging Rockies pulled ahead with a seven-run eighth inning -- highlighted by Nick Hundley's first career grand slam -- to beat the D-backs, 14-7, for their fifth win in six games.
The Rockies plated all of their runs in their final four frames with a sizeable chunk of the damage coming in a six-run fifth. Colorado was finally able to crack Arizona starter Robbie Ray when three singles started the inning, and the top of the order drove in runs on singles from Charlie Blackmon and Nolan Arenado accompanied by Carlos Gonzalez's double.
"He just couldn't stop the bleeding," D-backs manager Chip Hale said of Ray in the fifth.
The top of the Rockies' order came up big again in the eighth, with Blackmon taking third on Welington Castillo's throwing error attempting to catch him stealing, Arenado breaking the tie with a single, and DJ LeMahieu -- who reached for a career-high-tying 19th straight game -- scoring on a wild pitch. Back-to-back homers by Hundley and pinch-hitter Daniel Descalso put the game out of reach.
The D-backs got to Rockies starter Jorge De La Rosa early, with five runs in the first four frames, but were held in check by Colorado's bullpen. Jean Segura's single to lead off the sixth and A.J. Pollock's subsequent homer -- his first of the year -- were the only baserunners following De La Rosa's exit after five innings.
"Everyone contributed today," Arenado said. "It was a good win. That one inning we came back and tied the game, and then Pollock hit the homer, but nobody got down. Everybody felt fine, we felt confident, we felt like we could do something."
Rockies relievers Carlos Estevez and Adam Ottavino pitched a clean eighth and ninth inning, respectively, after poor outings in their last game on Wednesday. Ottavino was excited to pitch again after blowing a save and giving up five runs.
"I tried to keep it the same this time because I had a tough two days after that last game," Ottavino said. "I was going in there coming for blood. I didn't care how it turned out, but I was going to go as hard as I could one way or another." More >
MOMENTS THAT MATTERED Earning your unearned runs: Although none of the five runs De La Rosa gave up were earned, four of them were directly a result of his throwing error. After giving up back-to-back singles to Brandon Drury and Chris Owings to lead off the fourth, De La Rosa threw Ray's sacrifice bunt into right field, which plated two runs. After retiring the next two batters, De La Rosa surrendered two more runs on Paul Goldschmidt's double and Castillo's single.
"I didn't feel like he had his 'A' changeup tonight," Rockies manager Walt Weiss said. "He left some changeups up, and that's his pitch that he finishes at-bats with. He wasn't as sharp with that tonight. He was in a lot of deep counts and bad counts. He's got a knack for minimizing damage, but he had to grind, no question."
Sudden spirals: Ray seemed to be on top of his game through the first four innings, but in the fifth that changed quickly. Not all of the Rockies' hits that inning were well-struck, but Ray allowed five straight singles to open the inning and was not able to get out of the frame as Colorado scored six runs. Then in the eighth with two outs, Enrique Burgos retired the first two batters, before allowing the next five to reach. Silvino Bracho came on and allowed a grand slam and a solo homer and the game was suddenly out of reach.
"It got out of hand," Hale said. "Obviously tie game, two outs in the bottom of the eighth and you've got a chance to come in and score a run in the top of the ninth. Got away, again same deal [as fifth]." More >
Tapia shines in debut: Rockies No. 4 prospect Raimel Tapia did what he's been doing all year in the Minors in his first Major League at-bat: hit. Tapia leads all Minor Leaguers with 173 hits and reached on a pinch-hit infield single to the left side in the sixth inning. After Cristhian Adames sacrificed him to second, Tapia scored on a single to right by David Dahl, flying around third base with plus speed.
"I am very happy because I was having my first opportunity in the Major Leagues," Tapia said through an interpreter. "It was my first turn to get my hit in this league off of these pitchers. It's really exciting." More >
"I prayed before that. Just give me strength. I kind of played out the situation throughout the game. I was like, 'OK, I might have an opportunity here.' I wanted that at-bat, and when he threw those two sliders in the dirt, I thought a fastball might be coming, and I was able to stay on top of it. In those situations, I pop those balls up or hit fly balls, and it was nice to stay on top of the ball and hit a nice, low line drive." -- Arenado, on his go-ahead single
