Seth Smith hit a game-tying two-run double off Detroit closer Jose Valverde in the ninth inning and Coco Crisp capped Oakland's most dramatic comeback yet with an RBI single as the Athletics staved off elimination for a second straight night with a 4-3 victory over the Detroit Tigers in Game 4 of the AL division series Wednesday.
The A's rode 14 walkoff wins in the regular season to an improbable AL West title. Those paled in comparison to No. 15, which set up a win-or-go-home Game 5 against Justin Verlander and the Tigers.
Josh Reddick started the rally with a single just under the glove of diving second baseman Omar Infante. Josh Donaldson followed with a double off the wall in left-center and both runners scored on Smith's double. Two outs later, Crisp lined a single to right and Smith scored easily when Avisail Garcia couldn't handle the ball.
