Kansas City has won all eight of its games this postseason after winning the AL Wild Card game over the Athletics, sweeping the Angels in the ALDS and sweeping the Orioles in the ALCS. San Francisco defeated the Pirates in the NL Wild Card game, then won the NDLS over the Nationals in four games and the NLCS over the Cardinals in five games.
World Series Game 1 is on Oct. 21 in Kansas City.
