CINCINNATI -- Javier Valentin doesn't get many starts, so he tries not to waste them.
The Cincinnati catcher, starting for the first time in three weeks, homered in consecutive at-bats Friday night and Adam Dunn added his 40th of the season to send the Reds to a 9-1 victory over the Pittsburgh Pirates.
"I went a couple of weeks between starts, but it's been that way all year," said Valentin, stuck in a three-man catching situation with Dan Ross and Jason LaRue. "Tonight was my night."
Dunn became the second player in Reds history to hit at least 40 home runs in three consecutive seasons. Ted Kluszewski (1953-1955) was the first.
Valentin snapped a 1-1 tie with his seventh homer of the season, an opposite-field shot to left leading off the fourth inning. He followed in the sixth with a two-run line drive into the visitors' bullpen down the right-field line.
"He's probably been hurt more by having three catchers than anybody," Reds manager Jerry Narron said. "We haven't been able to find matchups that are favorable for him. Tonight, we were able to."
Valentin's home runs off Pirates starter Ian Snell were his first since his last start, against Pittsburgh on Aug. 18 in a 7-3 Pirates win. Snell also was the Pittsburgh starter in that game, but reliever Britt Reames allowed Valentin's homer.
Lohse (2-2) snapped his two-game skid. He allowed seven hits and one run with one walk and six strikeouts.
"My sinker or two-seamer or whatever you want to call it was working," Lohse said. "I was able to come in on them and run it up the ladder on them. It was one of those nights where I was able to put the ball where I wanted to and change speeds."
Snell (12-10) has lost his last two starts after logging three wins and a no-decision in his previous four. He allowed seven hits and four runs with three walks and five strikeouts in six innings. He has allowed a team-high 28 home runs in 29 starts.
"I feel like I'm home run prone," Snell said. "I feel like I'm brainwashed. I'm processing too much information for my first (full) year. There's a lot of stuff in my brain that I feel like I need to get washed away."
The nine runs were the most for the Reds in 15 games since they beat Houston 14-0 on Aug. 22.
"He didn't have late life on his pitches," Pirates manager Jim Tracy said about Snell. "He was getting the ball up. You could tell by the fly balls."
National League batting leader Freddy Sanchez (.341) went 0-for-4 for the Pirates, who had won three of their last four games.
Freel led off the first inning with his eighth home run. Ryan Doumit tied it with a solo homer in the second, his third of the season -- all since he was activated from the disabled list on Aug. 23 after missing almost three months with a torn left hamstring.
Dunn hit a two-run homer and Scott Hatteberg added a two-run single as the Reds sent 10 batters to the plate against three Pittsburgh relievers in a five-run seventh inning.
The Reds had at least one baserunner in every inning against Snell, while the Pirates had at least one baserunner in every inning except the third against Lohse.
- Freel's leadoff homer was his third this season and the fourth of his career. The homer was his first in 156 at-bats dating to July 22, when he hit two in an 8-7 win over Milwaukee.
- Hatteberg extended his career-high streak of errorless games to 91, the longest for a major league first baseman this season.
- Pittsburgh's Carlos Maldonado singled in the ninth inning for his first major league hit.
