The Red Sox, by virtue of their second straight walk-off win on Monday, are guaranteed a spot in the ALCS, the first of four teams to punch their ticket to MLB’s semifinals. The only thing left to be determined is just who they’ll be playing in the series. That will come down to the ALDS between the White Sox and Astros, a series which Houston leads two games to one. That could end as soon as Tuesday afternoon as the two sides play Game Four at 2:07 PM ET after it was rained out on Monday.
