CINCINNATI -- Here's how easy it looked to hit home runs at Great American Ball Park on Sunday: Todd Frazier lost his grip on the bat during a swing.

The ball wound up in the seats anyway.

Frazier's homer helped the Cincinnati Reds out-bash the Colorado Rockies 7-5 in a game that set a record for the 10-year-old stadium with nine home runs.

"I felt the bat slipping out of my hands," Frazier said. "I looked at the (slow motion) and it looks like my bottom hand is off. At first, I thought it was a short popup, but then I took a couple of steps and said, 'Oh.' It's a pretty interesting way to hit a home run. It was a pretty cool."

Brandon Phillips hit a three-run homer and Mat Latos allowed five hits -- all of them solo home runs.

"You have a day here with this kind of weather, the ball travels real well in this ballpark," Colorado manager Jim Tracy said. "The evidence of that is the Frazier home run that was hit. It looked to me like he had maybe a hand-and-a-half on the bat when he hit it, but what are you going to do? The ball went over the fence. It's that simple."

Colorado's Carlos Gonzalez hit two of them, and Troy Tulowitzki, Michael Cuddyer and Dexter Fowler also took the Cincinnati starter deep.

Joey Votto and Jay Bruce also homered for Cincinnati, which finished 6-1 on a seven-game homestand during which 29 home runs were hit -- also a ballpark best.

Latos (4-2) had three strikeouts without a walk in a season-high 7 1/3 innings to improve to 4-0 over his last seven starts.

"I didn't walk anybody?" he said. "That makes me feel a little better. As a pitcher, it's a bummer to let a team go yard five times. I was just in attack mode. I was just throwing strikes. It's always good when you throw strikes, but I don't make excuses. If those pitches are down, maybe they don't leave the ballpark. Maybe they're groundouts."

Said Reds manager Dusty Baker: "If you make quality pitches, you can pitch in a shoebox. If you don't, you can't pitch in Yellowstone."

Aroldis Chapman pitched 1 2/3 innings for his third save to help the Reds go 6-1 on the homestand.

Jamie Moyer (2-5) gave up seven hits and a season-high seven runs with one walk and two strikeouts in five innings. He also hit a batter with a pitch.

"I missed my spot to Bruce," Moyer said. "Probably the pitch to Phillips was up a little bit. I don't know if the pitch to Votto was a strike. Frazier's was an interesting swing."

Tracy blamed Moyer's location as much as the weather. The temperature was 90 degrees -- prime longball conditions.

"Jamie Moyer is all about location," Tracy said. "He did get the ball up at times."

Phillips put Cincinnati ahead 5-1 with his fifth homer of the season, a shot to the left-field seats with two outs in the third inning.

Gonzalez cut into the in the fourth, but Todd Frazier restored the four-run lead in the bottom half and the Reds actually scored a run without a homer on Ryan Hanigan's single and Zack Cozart's double that made it 7-2.

Cuddyer made it 7-3 with the longest drive of the game, a 448-foot blast off the center field batter's eye.

Gonzalez added his second homer with two outs in the sixth for his third two-homer game of the season and the seventh of his career.

Fowler set the record as a pinch-hitter in the eighth.

In the second inning, Tulowitzki tied the game after Votto went deep in the first inning, but Bruce put the Reds back on top with his first home run since May 8 at Milwaukee. Before that, he had been 2 for 34.
