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.
