Athletics 4, Astros 1
OAKLAND, Calif. — Josh Donaldson homered and doubled twice to back another solid start by Jesse Chavez, and the Athletics completed a series sweep. Chavez improved his team-best ERA to 1.38 through four starts. Jed Lowrie and Eric Sogard added two hits each for the A's, who have won 11 of 13. Oakland has the AL's best record despite a shaky defense that committed its AL-high 19th error.
