Jesse Root scored nine seconds into overtime to give fourth-seeded Yale a 3-2 victory over top-seeded Minnesota in the NCAA West Regional semifinals Friday in Grand Rapids, Mich.
Kenny Agostino intercepted Minnesota defenseman Ben Marshall’s pass behind the net and fed Root for his 10th goal of the season.
‘‘It was a good forecheck by Kenny,’’ Root said. ‘‘He stole the puck from the guy and passed it to me.’’
Marshall tried to swing the puck along the boards.
‘‘Kenny put a lot of pressure on the guy and took the puck,’’ Yale coach Keith Allain said. ‘‘He got him on a good angle and I knew [Marshall] was in trouble.’’
Yale (19-12-3) will play North Dakota (22-12-7) in the regional final Saturday at 4 p.m. for a spot in the Frozen Four in Pittsburgh.
Minnesota, the No. 2 overall seed in the 16-team tournament, finished the season 26-9-5.
‘‘I feel bad for our guys,’’ Gophers coach Don Lucia said. ‘‘It’s a one-shot deal, I didn’t see what happened.
“It happened so quick. I guess that’s why they call it sudden death.’’
Minnesota overcame a 2-0 deficit in the third period.
The Gophers cut it to one on Nate Schmidt’s power-play goal and tied it on Zach Budish’s marker with 6:20 left.
Agostino opened the scoring in the second period with his 16th goal of the season, and defenseman Gus Young made it 2-0 with a power-play goal in the period.
‘‘It was a tremendous team win,’’ Allain said. ‘‘Our guys played as well as they could . . . You have to get your nose bloodied sometimes to see how you respond. I think you saw how we responded.’’
Jeff Malcolm made 27 saves for Yale, and Adam Wilcox stopped 23 shots for Minnesota.
North Dakota 2, Niagara 1 — In the other semifinal, Andrew MacWilliam and Danny Kristo scored in a 57-second span early in the third period to spark North Dakota to a come-from-behind victory.
MacWilliam tied it with an unassisted goal, his second goal of the season, and Kristo put North Dakota in front at 2:53 with his 26th goal.
Jason Beattie scored for the Purple Eagles (23-10-5) in the second period.
Boston Bruins draft pick Zane Gothberg made 28 saves for North Dakota, and Carsen Chubak stopped 41 shots for Niagara.
