Willie Raskob scored at 11 minutes, 58 seconds of overtime to give Minnesota Duluth a 3-2 victory over Ohio State in a first-round game of the West Regional at Scheels Arena in Fargo, N.D. It was the fourth goal of the season for Raskob, a senior defenseman from Hastings.

After a scoreless opening period, the Bulldogs took a 2-0 lead in the second when Dominic Toninato scored at 49 seconds and Nick Wolff, with an assist from Raskob, at 13:41.

The Buckeyes rallied to tie on goals by Matt Joyaux and Gordi Meyer — his first of the season — in the middle of the third period.

Hunter Miska stopped 40 shots for UMD, Matt Tomkins 29 for Ohio State.

Minnesota Duluth (26-6-7) is unbeaten in 17 of its past 18 games (14-1-3). The Bulldogs were the top seed in the West, the Buckeyes (21-12-6) were seeded fourth.

 

Boston U. 4, North Dakota 3 (2 OT): Charlie McAvoy’s goal at 11 minutes, 48 seconds of the second overtime gave the Terriers the win over the defending NCAA champions in the early first-round game of the West Regional. It was his fifth goal of the season.

McAvoy scored off a pass from Clayton Keller to send the Terriers into Saturday’s regional final.

“I figured he would find me if I was open,” McAvoy said of Keller. “That’s exactly what he did and it happened pretty quick, but I’m glad it went in.”

The Fighting Hawks (21-15-3) had an apparent goal by freshman Dixon Bowen early in the first overtime waved off because of offsides.

“We thought that it might be an offside and it seemed like the longer it took [to review], the better chance that we were going to live another day,” Boston University coach David Quinn said. “ When the linesman buckled his helmet coming out of the box, we knew that we were going to get another chance.”

A sellout crowd of 5,219 gave the UND players a standing ovation at the end.

UND, seeded fourth in the region but playing in their home state, took a 1-0 lead on Rhett Gardner’s goal at 17:04 of the opening period.

BU (23-11-3) got the next three goals. Doyle Somerby scored at 2:05 of the second and Bobo Carpenter and Jakob Forsbacka Karlsson each scored in the first 4:24 of the third.

North Dakota tied the score in the third, on goals 3:20 apart by Ludvig Hoff at 12:14 and defenseman Christian Wolanin.

The rally came after a 14-minute to delay to replace a broken pane of glass when UND’s Mike Gornall checked Kieffer Bellows hard into the glass on a side wall.

Cam Johnson had 33 saves for UND, Jake Oettinger, a freshman from Lakeville, stopped 56 shots for BU.

“I know there’s not a single guy in that locker room that doesn’t think they gave everything they had,’’ Wolanin said. “Like I said, that’s the way it goes sometimes.’’

East Regional

Harvard 3, Providence 0: Tyler Moy’s power-play goal for the Crimson early in the second period broke a scoreless tie with the Friars and he later added an unassisted empty-netter with 1:51 left in the game at Dunkin Donuts Center in Providence, R.I.

Adam Fox, who had an assist earlier, had a goal late in the second period for Harvard which is on a 15-game winning streak, matching the longest streak in program history from the 1988-89 season. The Crimson also has a 17-game unbeaten streak since losing to Dartmouth 8-4 on Jan. 17.

Merrick Madsen, a junior from Acton, Calif., made a career-high 41 saves for the shutout, 17 of them in the opening period when he stopped several point-blank shots. Hayden Hawkey stopped 26 shots for Providence.

Moy beat Hawkey on a wrist shot from the bottom of the left circle to make it 1-0. Fox lifted a backhander from the top of the crease for a 2-0 lead.

Harvard was 1-for-4 on the power play, Providence 0-4.

Harvard (27-5-2) was the top seed in the region and the third overall seed.

The Friars (22-12-5), who lost in the Hockey East quarterfinals, had not played since March 11.

The Crimson won the ECAC regular-season and conference tournament titles. Madsen was named the Most Outstandind Player of the ECAC tournament, when he stopped 50 of 52 shots in two games, and he obviously remained hot.

Air Force 5, Western Michigan 4: The Falcons (26-9-5) built a 4-1 lead early in the third period and held on to edge the Broncos (22-12-5) in the second first-round game in Providence.

Jordan Himley scored in the first minute for Air Force and teammate Kyle Haak got an unassisted shorthanded goal at 11:02 to make it 2-0.

Frederik Tiffels answered with the first of his two goals for Western Michigan at 14:20.

Hask’s second goal early in the middle period made it 3-1 Air Force. Phil Boje then got a power-play goal for Air Force at 3:58 of the third.

Western Michigan got within 4-3 on goals by Griffin Molino, Sheldon Dries and Sheldon Dries, just 50 seconds and 1:13 after Boje’s.

Tyler Ledford got the eventual game-winner for Air Force at 6:45 to give the Falcons a two-goal lead.

“The turning point for us was getting that fifth goal and we sure needed it,” Air Force coach Frank Serratore said.

Tiffels scored his second goal with 1:59 to play.

Shane Starett had 22 saves for Air Force, Ben Blacker 25 for Western Michigan.
