HOUSTON (AP) — Jose Altuve homered 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 and earning himself AL Championship Series MVP.

Astros ace Gerrit Cole was waiting to pitch Game 7 on Sunday. Instead, the postseason star — undefeated since May 22 — may go for Game 1 at home against the NL champion Washington Nationals on Tuesday.

Yuli Gurriel hit a three-run homer in the first, and flashy outfield defense helped Houston’s relievers defeat the Yankees and their vaunted bullpen.

It almost fell apart in the ninth. Gio Urshela singled off Osuna leading off for his third hit of the game, and LeMahieu put a ball into the first row of seats in right field — inches over the glove of leaping George Springer — to tie it at 4.
