The first day of the 2018 NCAA Division I men’s hockey tournament brought two overtime games, one shutout and only the second time that the No. 1 overall seed has lost in the first round since the 16-team bracket began in 2003.

Buckle up for Saturday, then.

After Notre Dame and Providence won in the East Regional and Air Force and Minnesota Duluth advanced in the West, the first two Frozen Four spots will be decided Saturday.

And in the Northeast and Midwest regionals, the field will be cut in half.
