Athletics 8, Rockies 2: Jarrod Parker allowed three hits in seven scoreless innings and visiting Oakland finished off a three-game sweep while sending Colorado to its eighth consecutive defeat.
Brandon Moss homered and doubled twice, finishing with three RBIs as the Athletics dropped the spiraling Rockies to 0-9 in interleague play.
