Cincinnati, OH – Bronson Arroyo tossed his first shutout in 0, in the game series.
Arroyo (9-12) gave up six hits and recorded his first shutout since August 13, 2009. The right-hander struck out two and did not issue a walk in his first win since August 24.
"That was great. Just last week people were talking about taking him out," Reds manager Dusty Baker said of Arroyo.
Wandy Rodriguez (11-11) allowed two runs on four hits over seven innings for the Astros, who went 2-4 on a six-game road trip.
The Reds gave Arroyo all the support he would need in the first inning. Brandon Phillips led off with a single, stole second and scored on Heisey's bloop single to center.
Cairo's homer to left in the second made it a 2-0 game.
Arroyo retired the first 10 batters he faced in order. J.B. Shuck reached first on Edgar Renteria's fielding error in the fourth. Arroyo quickly got J.D. Martinez to ground into a double play.
Houston's first hit came in the fifth. Carlos Lee led off with a bloop single over the head of third baseman Cairo. After Matt Downs grounded into a double play, Chris Johnson doubled to right. Clint Barmes flied out to end the frame.
The Astros left a runner on third in the sixth and stranded runners on the corners in the eighth.
