HOUSTON -- Wandy Rodriguez found the mix he needed to stop the surging Cincinnati Reds.
Rodriguez pitched six solid innings, Humberto Quintero homered and the Houston Astros beat Cincinnati 3-2 on Sunday to snap the Reds' six-game winning streak.
Rodriguez (14-11) allowed two runs and nine hits. He struck out nine and walked one in his career-high 32nd start of the season.
"I felt great," said Rodriguez, who also has set career bests in wins, strikeouts (190) and innings (199 2-3) this season. "Everything was working good for me. My breaking ball was really good. I didn't think they could hit my breaking ball today."
Houston improved to 2-4 under interim manager Dave Clark, who was impressed with Rodriguez's crisp effort. The Astros had lost nine straight against the Reds.
"Wandy had a good breaking ball today," said Clark, who took over for Cecil Cooper last Monday. "He also had good command of his fastball. When you see him go to his breaking ball too often, that's when he has problems. But he was able to mix it up today."
Jeff Fulchino worked a perfect seventh, LaTroy Hawkins threw a scoreless eighth and Jose Valverde finished up for his 25th save. Valverde has converted 19 straight save opportunities and hasn't allowed a run in his last 12.
Reds starter Johnny Cueto (10-11) went 7 1/3 innings, giving up three runs and six hits. He struck out five and walked five.
"Johnny pitched outstanding," manager Dusty Baker said. "His pitch count wasn't that high, as long as he went. He just had that one inning where he lost control of the strike zone and they scored on a couple of fielder's choices."
The Reds had scored 10 runs apiece in each of the first two games of the series.
"I felt good and I was really locating my pitches well today," Cueto said. "The hitters have a job to do and I have a job to do. I can't tell them to hit. They scored a lot of runs the last two games. There's nothing I can do about it."
Houston scored twice in the third after loading the bases with nobody out. Lance Berkman and Carlos Lee each had an RBI grounder.
Quintero hit his fourth homer of the season in the fourth.
The Reds closed to 3-2 in the sixth on Jonny Gomes' RBI double and a run-scoring single by Ramon Hernandez.
