HOUSTON — Jose Altuve hit a game-ending homer off Aroldis Chapman with two outs in the ninth inning and the Houston Astros outlasted the New York Yankees 6-4 Saturday night to advance to the World Series for the second time in three years.

In a bullpen game with a back-and-forth finish, DJ LeMahieu hit a tying, two-run shot off Astros closer Roberto Osuna in the top of the ninth. Altuve answered with a two-run drive to left-center, setting off a wild celebration at Minute Maid Park.

Astros ace Gerrit Cole was waiting to pitch a potential Game 7 in this AL Championship Series on Sunday. Instead, the postseason star — undefeated since May 22 — could be lined up for Game 1 at home against the NL champion Washington Nationals on Tuesday night.
