Minnesota-Duluth and Michigan are going to the NCAA Frozen Four.
Minnesota-Duluth won the East Regional the hard way -- the Bulldogs beat Yale, the top seed in the tournament, 5-3 in Bridgeport, Conn., less than a half-hour from Yale's campus in New Haven. Michigan, coached by former Blues star Red Berenson, won the West Regional in St. Louis by edging Colorado College 2-1.
The other two Frozen Four berths will be decided Sunday. Notre Dame will play New Hampshire in the Northeast Regional final at Manchester, N.H., and North Dakota will play WCHA rival Denver for the Midwest title in Green Bay, Wis.
