The Boston Red Sox are ALDS champs after a roller coaster 4-3 win in game four Tuesday night. The Sox are headed for a showdown with the Houston Astros next.

What a nail biter.

The Sox scored four runs early and then had to hold on to their hats in the 9th inning.

A three run 3rd inning and a solo home run by Christian Vazquez staked the Sox to the 4-0.

The Yanks chipped away then Craig Kimbrel struggled bigtime in the bottom of the 9th. He allowed two runs to score and with the tying run at third, a slow grounder to third base was handled by Eduardo Nunez and he barely got Gleyber Torres out. In fact, the Yankees challenged the play to replay but the call 'out' held up.

Sox win and take the series three games to one.
