OAKLAND -- Matt Olson blasted a walk-off homer to lead off the 10th inning against relief pitcher Tony Sipp to send the A's to a dramatic 4-3 win over the Astros on Friday night at Oakland Coliseum.
The A's climbed to within a game of the first-place Astros in the American League West standings by handing Houston its first loss of the season in Oakland (7-1).
The Astros made a series of impressive defensive plays in the late innings to protect a one-run lead and nearly made another one to save the game in the ninth.
