The Oakland Athletics hope they are poised for another spectacular September like the one that propelled them to an improbable AL West title over the Texas Rangers on the final day last season. The Rangers arrive Monday for an important three-game series, clinging to a one-game division lead over Oakland with six meetings left. Coco Crisp and Stephen Vogt homered, A.J. Griffin struck out seven in seven innings, and Oakland completed a three-game sweep of fellow playoff contender Tampa Bay with a 5-1 victory Sunday.
