DENVER (AP) Johnny Cueto threw eight stellar innings to become the first 15-game winner in the majors and Kris Negron had a career-high four hits, including a tiebreaking single in the ninth, as the Cincinnati Reds beat the Colorado Rockies 3-2 on Friday night.
Cueto (15-6) allowed two runs and six hits to help the Reds snap a three-game skid. He's now 7-0 since a loss at San Diego on July 2.
Negron lined a two-out single up the middle off Adam Ottavino (0-4) to bring in Ramon Santiago with the go-ahead run.
Aroldis Chapman closed for his 26th save in 28 chances. Charlie Culberson drew a one-out walk and pinch-hitter Mike McKenry sent a shot down the line that first baseman Brayan Pena snared as he toppled over. Pena then touched first base with his glove to double up Culberson.
Nolan Arenado homered for Colorado, which has dropped seven of nine.
Jay Bruce brought in a run with a groundout in the Reds third and Santiago another with an RBI single in the fourth.
Cueto worked his way out of a jam in the sixth after giving up a tying RBI double to Corey Dickerson. With one out and the bases loaded, he struck out Culberson with a 95 mph fastball and then fanned D.J. LeMahieu with the same pitch.
The hard-throwing righty splintered quite a few bats with his heavy pitches running in on the hands of hitters. One of his few mistakes was an elevated fastball that Arenado hit into the left-field seats.
The Rockies turned to reliever Matt Belisle into an emergency starter when Franklin Morales was a late scratch after his wife went into labor. Belisle and five other relievers to kept the game close until the ninth.
Belisle allowed one run and tossed a season-high 49 pitches in three innings. It was his first start since May 25, 2008, when he was with the Reds.
Reds: INF Todd Frazier was out of the starting lineup with a balky back, which he hurt the night after hitting a ball off the end of his bat. "Pain shot up the right side of my back," Frazier said. He said he thinks it's a muscle strain in his lower back. He's day to day.
Rockies: Manager Walt Weiss said it "sounds like things went well" with SS Troy Tulowitzki's hip surgery Friday in Vail, Colorado. OF Carlos Gonzalez will have surgery on his left knee Monday. Both are out for the season.
Reds: RHP Dylan Axelrod is expected to be brought up from Triple-A Louisville on Saturday to fill in for the injured Homer Bailey, who's headed to the DL with a strained right elbow. It will be Axelrod's first major league start since last September.
Rockies: RHP Jordan Lyles (6-1, 3.70) will make his third start since returning from the DL. He missed two months with a broken left hand.
