Anthony Santander hit a game-ending two-run homer with two outs in the ninth inning, his 42nd longball of the season, and the Baltimore Orioles moved closer to a postseason berth with a 5-3 victory over the San Francisco Giants on Thursday. "That's a reminder of who we are," Santander said of an Orioles team that's nearly assured of a playoff spot but mired in a rough patch. Santander's shot off Ryan Walker (9-4) came after Casey Schmitt tied the game at 3-all with a single off Seranthony Domínguez in the top of the ninth.
