The Reds were hoping to get off to a good start on their 10-day, 11-game West Coast road trip.

Two games in, it could not have gone much better.

The Reds beat the San Francisco Giants 9-3 in Game 1 of the doubleheader Tuesday at AT&T Park.

Rookie left-hander Tony Cingrani (4-1) went 6 2/3 innings and allowed two runs on five hits. He walked three and struck out two. He threw a career-high 118 pitches.

That was more than enough as the Reds followed the 11-run, 17-hit performance Monday with a nine-run, 15-hit showing Tuesday. They hit three home runs for the second straight game.

The sixth, seventh and eighth hitters did the big damage: Todd Frazier went 2-for-5 with two RBI. Zack Cozart went 4-for-4 with a homer and two RBI. Devin Mesoraco went 3-for-4 with a three-run homer.

"We've got some hot bats," Mesoraco said. "You ride it out as long as you can. You want to go out and put up as many runs as you can -- especially early to take a little pressure off the starting pitcher.

"That's what we were able to do the last two nights."

No one is hotter than Mesoraco. He is 10-for-his-last-20 with two home runs and three doubles.

"I feel good," Mesoraco said. "Coming off the All-Star Break, those three days off, you're able to physically get better and mentally take a little break. I came back. I've been able to go out and relax and be in a good position to hit. My swing has felt good lately. It's starting to show."
