Coco Crisp sent the Oakland faithful home happy on Thursday by cracking a 12th-inning walkoff homer to lead the A's to a 3-2 win over the Mariners. He crushed Hector Noesi's second pitch of the inning, a fat 93 mph fastball, over the right field wall. Crisp's homer was the story, but the underrated center fielder had begun stuffing the box score before the game entered extra frames. He finished 1-for-3 with three walks, two runs scored and his second steal of the season. Crisp had a career year in 2013, hitting 22 round-trippers and swiping 21 bags. Another 20/20 season appears to be in the offing for the 34-year-old.
