Alberto Callaspo hit a three-run homer and the Oakland Athletics went deep four times to back Sonny Gray's strong pitching Friday night in an 11-3 rout of the Houston Astros.
Josh Reddick and Coco Crisp each added a two-run shot for Oakland. Yoenis Cespedes hit a solo homer in the second inning to follow up his two-run single in the first against Jarred Cosart (1-2).
Cespedes' single came one batter before Callaspo connected for his second home run of the season. John Jaso drew Cosart's fourth walk of the first inning before Reddick hit his first homer with his own towering drive to right field.
That chased Cosart, who retired only one batter before being replaced by Paul Clemens.
Gray (3-0) gave up more than one earned run for the first time this season.
