Coco Crisp walked off Oakland Sunday, propelling the A's to a 5-4 victory and four-game home sweep of the Yankees by singling home Derek Norris in the 12th inning. The A's have won five in a row, and are now a stunning 14-2 in the month of July. Crisp finished his day 2-for-3 with a steal after entering as a pinch-hitter in the eighth. The swipe was his 19th of the season. He's hitting .248/.309/.331.
