Athletics 2, Astros 0
OAKLAND, Calif. — Jesse Hahn pitched into the seventh inning in his return to the majors and combined with two relievers on a four-hitter to lead the Athletics to a game over .500. The right-hander faced the minimum through five innings. He gave up three hits and allowed only one runner past first base to win for the first time since July 1. John Axford retired four batters and Ryan Madson worked the ninth for his eighth save, completing the A's first shutout of the season.
