Several players gathered around a high-definition TV on one end of the Oakland Athletics' clubhouse, shouting and screaming at the highlights they just made happen with another dose of late-inning drama. A tying home run. A game-ending single. Players streaming out of the dugout, mobbing the final hitter on the field. A whipped-cream pie in the face -- maybe two -- and a sports-drink bath to wash it all down. No matter how many times the scene unfolds, it never seems to get old in Oakland this season. Seth Smith hit a tying homer in the ninth inning, Coco Crisp singled home the winning run in the 12th, and the surging A's rallied from four runs down to stun the New York Yankees 5-4 on Sunday and complete a four-game sweep. Oakland improved to 14-2 in July, the best record in the majors during that span, with a league-leading 11th walk-off win.
