Worth noting

• The A's bullpen entered Saturday having yielded just 12 runs over the last 20 games for a 1.61 ERA. Their 2.25 ERA is the lowest in the American League, and they haven't allowed a run to Houston this season.

• Entering Saturday, Oakland was successful in each of its last 12 stolen-base attempts. The A's were 16-for-17 (94.1 percent), the best rate in the Majors.
