After Chapman tied the game in the eighth with his second homer, the A's returned for the ninth with more firepower. Yonder Alonso drew a leadoff walk against lefty Andrew Miller, at which point Indians manager Terry Francona turned to Shaw, who worked a full count against Davis before surrendering the game-ending shot to right-center field.
Edwin Encarnacion homered for Cleveland, a two-run shot in the fourth against right-hander Paul Blackburn, who went six innings in his third big league start. The rookie allowed three runs on five hits with four walks and four strikeouts.
