DENVER — Jon Gray turned the page on bad pitches a little faster than usual. That allowed him to salvage his whole night.

Gray settled down after a shaky start, pinch-hitter Noel Cuevas came through with a tiebreaking triple in the sixth inning and the Colorado Rockies began a long homestand by beating the Cincinnati Reds 5-4 on Friday.

Nolan Arenado homered early for Colorado in the first of nine in a row at Coors Field, where the NL West-leading Rockies have struggled this season. The team is tied for the second-fewest home wins (eight) in the majors.

Grey (5-6) threw 100 pitches over six taxing innings in allowing four runs. He didn't have his command early on, but finally found some semblance of a groove. Typically this season, it's been the good or the bad with Gray and rarely in between.

Consider: In his six losses, he has a 10.05 ERA. In his five wins, he has a 1.36 mark.

This one looked headed down a bad road. Trailing 4-1 in the third, the Rockies tied it on Tony Wolters' bases-loaded walk shortly after Gerardo Parra's two-run single. It was Colorado's biggest comeback of the season.

"Things didn't start off very good at all. I knew it was going to be a grind from there on out," Gray said. "That's what I tried to do — make every single pitch. Forget about the bad ones and move on to the next one."

The bullpen did its part, too — Mike Dunn pitched around a leadoff single in the seventh and Adam Ottavino did the same in the eighth. Wade Davis struck out two of three in the ninth to earn his major league-leading 18th save.

Cuevas delivered in the sixth after Wolters led off with a walk. Cuevas lined a slider from Sal Romano (2-6) into the right-field corner for his first career triple.

"I'm glad I was able to get a hit against a righty. It gives me the confidence of, hey, I can hit against righties, too, not just lefties," Cuevas said. "Hopefully in situations like that in the future, they give me that vote of confidence and throw me out there."

It was another rough outing for Romano, who lasted 5 1/3 innings and permitted five runs. The right-hander has given up 18 runs over his last 12 2/3 innings during a three-game skid.

"I felt my stuff, the way I felt, was better than my numbers today," Romano said. "Still, another loss."

Eugenio Suarez hit a two-run homer and leads the NL with 40 RBIs. Joey Votto had a single and a double in the opener of a nine-game road swing. The Reds are 9-15 away from home.

Arenado hit his ninth homer of the season, a solo shot in the first.

TRAINER'S ROOM

Rockies: 2B DJ LeMahieu (sprained left thumb) is playing catch and hitting "a little bit," he said. LeMahieu was placed on the disabled list May 14. "Getting better every day," he said.

TO K OR NOT TO K

Arenado isn't all that troubled by Colorado fanning at least 10 times in 23 games this season.

"Strikeouts aren't a big deal. It's a matter of when strikeouts are," he said. "With nobody on and you strike out, it hurts but it doesn't hurt you as bad as when you have runners in scoring position and have a chance to get a run on the board."

NEED FOR SPEED

Reds interim manager Jim Riggleman inserted struggling outfielder Billy Hamilton into the lineup more for his ability to cover ground at spacious Coors Field. Batting ninth in the order, Hamilton went 1 for 4 to slightly raise his average to .200. He also showed off his wheels by running down Parra's drive in the seventh.

"His defence is extraordinary," Riggleman said. "When we play in these big parks out West, we like to have him out there."

UP NEXT

Reds: RHP Tyler Mahle (4-6, 4.53 ERA) is tied with Los Angeles Angels' Shohei Ohtani for the most strikeouts (52) in the majors this season among pitchers 23 and younger. Mahle will make his first start against Colorado on Saturday.

Rockies: LHP Tyler Anderson (3-1, 4.74) held the Reds to two runs over six innings in a win on May 19, 2017.
