DENVER -- Jorge De La Rosa had his best start since rejoining the rotation 10 days ago and Tony Wolters hit his first career home run as the Rockies topped the D-backs, 11-6, on Saturday at Coors Field.
De La Rosa held the D-backs to one run -- on Paul Goldschmidt's double after Jean Segura's leadoff walk -- in six innings. The Rockies' Charlie Blackmon quickly erased that deficit with his 17th career leadoff home run, which tied him with Curtis Granderson for the most in the Majors since 2013, Blackmon's rookie season.
"I'm getting my confidence back," De La Rosa said. "I've been winning the last four games I threw. It's huge for me and good for the team. Just have to keep doing the same thing, and try to win more games."
D-backs starter Shelby Miller surrendered a season-high seven runs over six innings and gave up 11 hits -- at least one to every Rockies starting position player. Wolters led the way with three hits, including a two-run double and a homer, and four RBIs. Daniel Descalso added an RBI single in the fourth, and Nolan Arenado's fifth-inning double drove in another run.
The Rockies' bullpen allowed at least five runs for the third time in four games. Michael Bourn homered off Chad Qualls, and Jake Lamb and Segura also drove in runs off him, but Gonzalez Germen earned his first save of the season despite giving up an RBI double to Bourn. DJ LeMahieu padded the lead in the ninth with a three-run home run.
"Guys came back, did a good job," D-backs manager Chip Hale said. "I thought if we could hold them to one in the bottom of the eighth there, we'd have a chance. But it's tough. It's a tough lineup to navigate, and we've got guys pitching in roles that are unfamiliar to them."
MOMENTS THAT MATTERED Big double plays: De La Rosa was able to navigate scoreless fourth and fifth innings despite walking two and giving up three hits. He was able to coax a double play ball out of the speedy Bourn on a fastball in the fourth and another double play ball on a splitter to Peter O'Brien to end the fifth.
"That's what he's done so well for so long here," Rockies manager Walt Weiss said. "He'll get guys on base, but he's a master at minimizing damage, and it's because he can get a ground ball and get two outs with one pitch. He gets soft contact; he's really good at it."
Shelby struggles: The D-backs hoped Miller had turned the corner after he allowed just one run over 6 2/3 innings against the Phillies in his last outing. Prior to that, Miller had been on the disabled list with a sprained right index finger, but it was really more about giving him a mental break after a rough start to the season.
"I think it's just one of those things you have to bounce back from and get ready for the next one," Miller said. More >
Barnes' evasive slide: It looked like the Rockies' rally may have been slowed when Brandon Barnes was ruled out at home on Wolters' fourth-inning double. However, Rockies video coordinator Brian Jones told Weiss to challenge the call, which the umpires overturned, ruling that Barnes slid his right hand under Welington Castillo's tag to touch home plate.
"In real time, I thought he was out," Weiss said. "We got a call down from Jonesie that said, 'Hold on, he might have got his hand in.' Even on a borderline play when it might be a run, you've got to challenge those. He did a good job of holding out on that one and making sure we got a good look at it."
Missing chances: The D-backs had a chance to score more than just one run in the first inning, but they left a pair of runners stranded. They also left two on in the second and fourth. A chance for a possible big inning was thwarted when O'Brien grounded into an inning-ending double play with runners on the corners in the fifth.
"We had opportunities to score," Hale said. "The two double plays hurt us."
"Jorge had all his pitches. At the beginning, we were trying to get his command. He figured it out, we adjusted. His changeup was there, his curveball is really good, and he's getting back to his old self. I'm proud of him and grateful to have him throw six right there. That was clutch." -- Wolters
