Seth Smith hit a two-RBI double to tie the game in the ninth and scored the winning run on a Coco Crisp walk-off single in Wednesday's 4-3 ALDS Game 4 win over the Tigers. Smith followed a Josh Reddick single and Josh Donaldson double with a double of his own before scampering home on Crisp's two-out, walk-off single through the right side. The A's not only scored three of their four runs in the final frame but also doubled their hit total. Justin Verlander and Jarrod Parker will square off in Game 5 Thursday.
