 The Orioles cannot have a winning record against the Oakland A's, but astonishingly enough, it is razor thin, the margins. The Orioles enter play today 142 and 144 all-time against the Oakland A's. So the best they can be is one game under .500 against the Athletics. Jordan Westbrook takes one low, 1-0. Had the Orioles swept the A's this weekend, they would have had a winning record against the Oakland A's. They'll fall a game short of that if they win today.
