PHOENIX - Bronson Arroyo pitched seven strong innings, Aaron Hill had two late RBIs and the Arizona Diamondbacks beat the Houston Astros 4-1 on Tuesday.
Arroyo (6-4) matched Houston starter Brad Peacock through seven innings before the Diamondbacks scored two runs off Josh Fields (1-4) in the seventh.
Hill hit a sacrifice fly in the inning and Cody Ross knocked him in with a double to right-center after an error by Astros shortstop Jonathan Villar. Hill added a run-scoring double in the eighth inning to put Arizona up 4-1.
Paul Goldschmidt also homered and Addison Reed worked a perfect ninth for his 16th save. Arizona has won six of eight.
Jon Singleton had three hits for the Astros.
Arroyo has pitched well against the Astros, entering Tuesday s start 9-1 with a 2.05 ERA his last 12 starts against them.
He labored through the first two innings, working around six baserunners while throwing 42 pitches. The right-hander breezed through the next three innings before Matt Dominguez followed Singleton s leadoff double by lining a run-scoring single through Arizona s drawn-in infield to tie the game at 1-all.
Arroyo got some defensive help along the way, including a pair of strike-out, throw-out double plays and a nifty grab up the middle by Hill on a short-hop in the seventh inning. Arroyo allowed a run on six hits and struck out five.
Peacock won his previous three starts and was sharp in his first game against Arizona.
Goldschmidt splashed a solo homer into the pool in right-center off him in the first inning, but the right-hander allowed two more hits after that - a pair of infield singles in the second.
Peacock walked four and struck out three in six innings.
