The Astros improved to an American League-best 27-14, giving them the best start through 41 games in franchise history. Sitting atop the AL West, this is the latest the Astros have led their division since May 22, 2004.
Keuchel (6-0) allowed six hits and no earned runs in seven innings to lower his ERA to 1.67. He's won eight straight decisions dating back to last year, which is the longest streak by a starter in the majors. And his 6-0 mark this year is the best by an Astro since Roger Clemens opened the 2004 season at 9-0.
The A's have now lost eight of their lost 10 games, and Jesse Hahn falls to 1-4 on the season.
