Diamondbacks 4, Astros 1
PHOENIX — Hernando High grad Bronson Arroyo improved to 10-1 against the Astros. He labored through the first two innings, allowing six baserunners and throwing 42 pitches. But he settled down and was helped by two strike-out, throw-out double plays. Aaron Hill drove in the go-ahead run in the seventh with a sac fly and an insurance run in the eighth with a double.
