HOUSTON - Bronson Arroyo got his first win of the season and Adam Dunn hit a three-run homer to help the Cincinnati Reds beat the struggling Houston Astros 11-2 on Tuesday night.
It was the Reds' largest winning margin and Houston's ninth loss in the last 10 games.
In his sixth start, Arroyo (1-2) retired the first nine batters before walking Craig Biggio to start the fourth. Mike Lamb singled and Biggio scored on a sacrifice fly by Luke Scott later in the inning.
Arroyo walked Lance Berkman to start the sixth and retired the next six batters before being replaced by John Coutlangus in the eighth.
