Yale, the last team to qualify for the NCAA Tournament, became the first team to earn a berth in this year's Frozen Four by scoring four times in the third period to beat North Dakota 4-1 on Saturday in the final of the NCAA West Regional in Grand Rapids, Mich.
It's the first trip to the championship round since 1952 for Yale, which didn't qualify for the tournament until Michigan lost to Notre Dame in the CCHA tournament final on Sunday.
Jesse Root, whose overtime goal on Friday eliminated top-seeded Minnesota, broke a 1-1 tie with 4:56 left in regulation with a power-play goal. He worked his way into the left circle and whipped a shot from the faceoff dot that beat goaltender Clarke Saunders.
Freshman Stu Wilson added an insurance goal when he knocked in a rebound with 2:21 remaining, and Kenny Agostino hit the empty net with a minute to play.
