PHOENIX -- A.J. Pollock's single off Brad Peacock scored Deven Marrero from third base as the D-backs walked off the Astros, 4-3, on Saturday night at Chase Field.
The hit capped a back-and-forth game that saw the D-backs lose a late lead, while the victory snapped Arizona's three-game losing streak.
Jeff Mathis led off the ninth with a bunt single, and after pinch-runner Jarrod Dyson was erased at second on Marrero's bunt attempt, Chris Devenski struck out David Peralta for the second out of the inning before walking Chris Owings and Paul Goldschmidt to load the bases.
