Todd Helton went 2-for-4 with a home run and three RBI to lead the Colorado Rockies to a 6-3 win over the Cincinnati Reds in the first of a three-game set at Great American Ball Park.
Jordan Pacheco had an RBI double and Troy Tulowitzki had three hits, drove in a run and scored a pair for the Rockies, winners in two straight since dropping six in a row.
Christian Friedrich (2-1) allowed three runs on seven hits over five frames. He also struck out six and walked just one.
Rafael Betancourt picked up his eighth save of the season after throwing a perfect ninth.
Todd Frazier drove in a pair of runs and Ryan Ludwick had an RBI double for the Reds, who had a six-game winning streak halted. Joey Votto went 4-for-4 with two doubles.
Johnny Cueto (5-2) was pegged with the loss after giving up five runs on 11 hits over 4 2/3.
The Rockies went ahead 2-0 in the second when Helton hit a two-run homer. Tulowitzki opened the frame with a double before Helton belted his fifth home run of the year.
Colorado tacked on a run in the fourth to take a 3-0 lead. Wilin Rosario hit a ground-rule double, moved to third when Friedrich singled before scoring on Eric Young's bloop single to center.
"That was my first professional hit," Friedrich said. "The last time I had one was maybe in high school, a grounder in the six-hole in summer ball. It felt great."
The Reds used a three-run rally in the bottom of the frame to knot it up at 3-3. Votto and Brandon Phillips hit back-to-back singles. Ludwick doubled two hitters later to plate Votto. Frazier followed with a double of his own to score Ludwick and Phillips.
But the Rockies added two in the fifth to go ahead once again. Carlos Gonzalez doubled to open the inning and Tulowitzki singled to put runners on the corners. A Helton single scored Gonzalez. Pacheco added an RBI double with two outs.
The Reds put runners on second and third with two outs in the seventh but former-Reds pitcher Matt Belisle was able to strike out Phillips to end the threat.
"We had some opportunities, had some chances with runners on base, but just couldn't get that two-out hit," Reds manager Dusty Baker said.
A Tulowitzki single in the ninth scored Gonzalez to put Colorado up 6-3.
