The first day of the 2011 NCAA hockey tournament is in the books, and the results were both interesting and surprising, to say the least. Four games were played and two of them went to overtime. Based on the seeds, no upsets happened in the two overtime games, but that wasn't the case for the games that didn't require an extra session. Those two games had upsets happen, and one was especially shocking.
Here is a look at the NCAA hockey tournament scores from Friday's games:
East Regional
No. 3 Minnesota-Duluth def. No. 2 Union (NY), 2-0
No. 1 Yale def. No. 4 Air Force, 2-1 (OT)
West Regional
No. 2 Michigan def. No. 3 Nebraska-Omaha, 3-2 (OT)
No. 4 Colorado College def. No. 1 Boston College, 8-4
The finals for these two regions will be played on Saturday. Yale will play Minnesota-Duluth and Michigan will surprisingly play Colorado College. The winners will advance to the Frozen Four, which will be held in Minnesota in two weeks.
