OAKLAND, Calif. -- 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 RBI 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.

Houston right-hander Collin McHugh (13-6) was charged with the loss and fell short in his bid to become the American League's first 14-game winner. He used a career-high 121 pitches to get through six innings, allowing two earned runs and five hits with three walks and eight strikeouts.

Outfielder Preston Tucker hit a solo shot off Chavez in the fourth inning.

Astros shortstop Jose Altuve went 2 for 4 to extend his hitting streak at O.Co Coliseum to 19 games, the longest active streak for any player.

The A's (50-62) are last in the AL West but defeated the division-leading Astros (61-51) for the second straight game.


Athletics: OF Coco Crisp (illness) was replaced in left field by Sam Fuld in the top of the third inning. . LHP Sean Doolittle (strained left shoulder) said he felt "rusty" during Friday's scoreless one-inning rehab stint with Class-A Stockton and that he plans to pitch again Sunday.


Astros: RHP Mike Fiers (5-9, 4.17) will make his first start for Houston since being acquired via trade from Milwaukee on July 30. Fiers gave up six earned runs over five innings of relief work in his Astros debut on Monday.

Athletics: RHP Chris Bassitt (1-4, 2.64) seeks his fourth straight quality start for the A's. He is 1-2 with a 2.25 ERA since being recalled from Triple-A Nashville on July 25.
