The AL West-leading Oakland A's arrived in Texas hoping to win the series. They did a whole lot more than that. After their starting pitcher was scratched only an hour before the game, and their top slugger also was taken out of the lineup, the Athletics kept winning. Tommy Milone threw five solid innings and Oakland hit three home runs in a 5-1 win Sunday to complete a three-game sweep of the chasing and slumping Texas Rangers.
