Oakland scored three in the second, highlighted by rookie Matt Chapman's RBI triple to right field. The A's capitalized on two Houston errors in the inning.
Then in the sixth, the A's added three more when Jed Lowrie drew a bases-loaded walk and Khris Davis followed with a two-run single, upping his RBI total to 101. After setting a career-high with 102 RBIs last year, Davis is the first Oakland player to have back-to-back 100-RBI seasons since Miguel Tejada (2000-03) and Eric Chavez (2001-03).
The A's blew the game wide open with a five-run eighth on four bases-loaded walks and an RBI single by rookie Joey Wendle.
