OAKLAND, Calif. (AP) - Josh Donaldson's eighth-inning triple drove in Josh Reddick for the winning run and Oakland Athletics overcame starter A.J. Griffin's early struggles for a 4-3 victory over the Houston Astros on Tuesday night.
Reddick drew a two-out walk off reliever Rhiner Cruz (0-1) and took off for second just before Donaldson's hit down the right field line landed just fair. Houston outfielder Rick Ankiel made a diving attempt but came up short as Reddick raced around the bases.
Eric Sogard added a career-high three hits for the A's, who have won all five games against the Astros this season.
Carlos Pena homered for Houston, which has lost four straight.
Grant Balfour pitched the ninth for his second save in as many chances after Sean Doolittle (1-0) gave up Pena's tying home run.
