DENVER -- Tyler Chatwood was off his game -- and that was a good thing.
Usually one to throw harder and harder in times of trouble, Chatwood reversed that trend and leaned more on his off-speed pitches.
Throwing slower made him even more steady.
Chatwood pitched two-hit ball into the eighth inning before exiting after deflecting a comebacker with his pitching hand, Mark Reynolds homered for a third straight game and the Colorado Rockies beat the Arizona Diamondbacks 5-2 on Sunday.
"I didn't get predictable, throwing fastballs in fastball counts," said Chatwood, who has a fastball around 97 mph and a curve at 77. "I took (that approach) out there and it translated."
Pat Valaika lined a two-run homer and Charlie Blackmon added a solo shot into the second deck as the NL West-leading Rockies took two out of three from the Diamondbacks.
"Two out of three will get you to the playoffs," Reynolds said. "That's what we preach around here."
Chatwood (3-4) surrendered a single to Jake Lamb in the fourth and was cruising along until he tried to corral DanielDescalso's infield hit with his right palm to start the eighth. Chatwood took a warmup toss before manager Bud Black motioned to the bullpen with the Rockies leading 5-0. Chatwood allowed one run over seven innings.
"I'm good. It didn't hurt," Chatwood said.
Taijuan Walker (3-2) surrendered three runs -- one earned -- over 5 2/3 innings. He was undone by some faulty fielding, including a flyball lost in the sun.
Arizona scored twice in the eighth before Mike Dunn got the final out of the inning with lightning visible in the background and the wind picking up. Rain followed and the game was delayed 1 hour, 22 minutes.
Greg Holland pitched a 1-2-3 ninth for his 13th save in as many chances.
The game-changing play took place in the sixth, when Reynolds reached on second baseman Chris Owings' two-out error. Trevor Story followed with a towering fly to right, with David Peralta initially stumbling after it. Peralta got back to his feet in time, but then lost the ball in the sun, allowing Reynolds to score from first on Story's double.
"I had my sunglasses on my head, but the sun wasn't hitting right at me," Peralta explained. "But when I fell down and tried to look for the ball I looked straight to the sun."
Reliever J.J. Hoover entered and gave up Valaika's first homer of the season to make it 4-0.
That was more than enough for Chatwood, who bounced back from two less-than-stellar outings.
"Not one guy hitting looked like they were comfortable up there," Reynolds said of Chatwood's performance. "That was good Chatty."
TRAINER'S ROOM
Diamondbacks: Walker was hit on side of his right foot by a liner in the second inning. He stayed in the game.
Rockies: OF Carlos Gonzalez (calf) went hitless in his return to the lineup after missing two games. ... 3B Nolan Arenado was given a day off.
Reynolds finished 2 for 4 to raise his average to .321. His 11 homers are among the NL leaders.
"My swing is on time. I'm finding barrels and getting it up in the air," Reynolds said. "That's a good combo."
