Line score {{linescore The one-game playoff was touted as a duel between the Royals'
James Shields and the Athletics'
Jon Lester, but neither starting pitcher would earn a decision in the game. Oakland's
Brandon Moss homered early off of Shields with
Coco Crisp on base, giving the Athletics a 2–0 advantage; Kansas City halved the lead in the bottom of the first when
Billy Butler singled to score
Nori Aoki.
Lorenzo Cain and
Eric Hosmer had RBI hits for the Royals in the third inning, vaulting Kansas City to a 3–2 lead. In this third inning, Oakland catcher
Geovany Soto left the game with a thumb injury sustained in a play at the plate. Soto had started the game because he would be more adept at controlling the running game of the Royals. This would come back to haunt the Athletics later in the game. The fourth and fifth innings were scoreless, but a big sixth inning gave Oakland a large lead.
Sam Fuld singled to lead off the inning, and Shields was relieved by
Yordano Ventura after walking
Josh Donaldson. Ventura's first batter, Moss, belted a three-run home run to give the Athletics a 5–3 lead. After Ventura was relieved by
Kelvin Herrera,
Derek Norris and Crisp singled in two additional runs. Both Oakland and Kansas City batted fruitlessly in the seventh inning, and Royals relief pitcher
Wade Davis recorded three straight outs in the top of the eighth. In the bottom of the eighth, with Kansas City six outs away from having their season ended, the Royals manufactured a productive inning of their own.
Alcides Escobar singled, and then stole second base with Nori Aoki at the plate. Lorenzo Cain singled, scoring Escobar. Cain stole second base himself with Eric Hosmer batting; Hosmer was then walked, at which point starting pitcher Jon Lester was relieved by
Luke Gregerson. Nerves seemed to get the better of Gregerson, who allowed Billy Butler to single and score Cain, and then allowed Hosmer to score from third base on a wild pitch. After walking
Alex Gordon, Gregerson struck out the next two batters to preserve the Athletics' lead, but the Royals had narrowed the score to 7–6. Closer
Greg Holland took the mound for Kansas City and was somewhat shaky, walking three batters, but mustered the three required outs without major damage, and Kansas City took their one-run deficit to the bottom of the ninth. Oakland's closer,
Sean Doolittle, pitched in relief of Gregerson. Pinch-hitter
Josh Willingham hit a bloop single and was replaced by pinch-runner
Jarrod Dyson. Dyson moved to second base on a successful bunt from Alcides Escobar, and then stole third with Aoki at bat. Aoki hit a deep sacrifice fly to right field for the second out of the inning, but Dyson was able to jog home, tying the game at 7–7 and completing the Royals' four-run comeback. Cain lined out to end the inning for Kansas City.
Brandon Finnegan, who only three months earlier had pitched for
TCU in the
College World Series, began a strong inning of work in the tenth, replacing Greg Holland and recording three outs in quick succession. The Royals advanced Eric Hosmer to third base with two outs in the bottom of the tenth, but
Salvador Pérez grounded out, putting a Royals victory on hold. Finnegan again pitched well in the top of the 11th, allowing only one hit and striking out Brandon Moss, who had already hit two home runs. Kansas City's offense produced in the bottom of the 11th a situation identical to that of the tenth; the winning run stood away with two outs, but
Jayson Nix struck out to end the inning. Finnegan began the 12th inning by walking
Josh Reddick, who advanced to second on a sacrifice bunt by
Jed Lowrie. Finnegan was then relieved by
Jason Frasor. Pinch-hitter
Alberto Callaspo of Oakland took a wild pitch from Frasor, allowing Reddick to go to third base. Callaspo then hit a line drive to left field, scoring Reddick. The new pitcher Frasor quickly stopped the bleeding by retiring
Derek Norris and
Nick Punto, but the Athletics had retaken the lead, 8–7. Lorenzo Cain failed to get the bottom of the 12th off to a promising start for Kansas City when he grounded out. The Oakland Athletics were two outs away from advancing to the ALDS. However, Hosmer nursed a lengthy at-bat into a deep hit off the left field wall that was poorly fielded, allowing him to reach third base.
Christian Colon then managed an infield single to tie the game again, scoring Hosmer. Oakland pitcher
Dan Otero was replaced by
Fernando Abad, who threw to only one batter, Gordon, who popped out. Abad was then relieved by
Jason Hammel. Christian Colon, still on first base, stole second (the seventh steal of the game for the Royals) with Pérez at the plate, after a
pitchout was dropped by
Derek Norris. Pérez (who was 0-for-5 at this point) then singled down the line to left field, the ball narrowly missing the outstretched glove of
Josh Donaldson. Colon scored, ending the marathon game with a Royals victory and a ticket to the ALDS against the
Los Angeles Angels of Anaheim. ==Aftermath==
