The Oakland Athletics return to the Coliseum Friday night where they will begin a three-game series against the AL East leading Baltimore Orioles. The A’s snapped a five-game losing streak Wednesday with an 8-0 win in St. Louis. They will go with an opener again Friday with Francisco Perez starting while Luis Medina is expected to see the bulk of the innings. The Orioles will go with right-hander Kyle Gibson.
Perez has made just two appearances for the Athletics this season allowing three hits and one run over two innings. Medina will follow for the first time since early July.
