OAKLAND, Calif. (AP) Danny Valencia delivered an early two-run double and right-hander Jesse Chavez went seven impressive innings to lead the Oakland Athletics to a 2-1 victory over the Houston Astros on Saturday.

Valencia produced in his second straight game as Oakland's new cleanup hitter, ripping a two-run double to the gap in right field in the bottom of the first. He finished 2 for 4 and is 5 for 12 with three RBIs in three games since the A's acquired him off waivers from the Toronto Blue Jays on Monday.

Chavez (6-11) allowed an earned run, six hits and four walks while striking out four to record his first victory since July 19. Chavez completed at least seven innings for the first time since June 17, a span of nine outings. He rebounded nicely from a bad start on Monday when he gave up six earned runs in 3 2-3 innings in a 9-2 loss to the Baltimore Orioles.
