The four teams advancing to next weekend's women's Frozen Four punched tickets Saturday to Hamden, Connecticut.
Minnesota, Wisconsin, Clarkson and Mercyhurst each won a single-elimination NCAA Tournament quarterfinal. All but Mercyhurst, which upset #2 Cornell, were at home by favorites.
The two-time defending Gophers (37-1-1) kept the hopes for a three-peat alive with a 5-1 win over Boston University (23-12-1). Kelly Terry scored a hat trick Saturday against the Hockey East Tournament champion Terriers in what was a repeat of last year's national championship game.
Minnesota will play WCHA rival Wisconsin (27-7-2), which defeated Harvard 2-1 at a sold-out LaBahn Arena. A pair of Badgers juniors in Blayre Turnbull and Katy Josephs lit the lamp Saturday, but the biggest story might be UW senior goaltender Alex Rigsby. She made what could be the save of the season on the Crimson (23-6-4) in the third period with her stick.
The Badgers and Gophers have met 4 times this season with Minnesota taking all four games.
Mercyhurst (23-8-4) held on to defeat the Big Red 3-2 at Lynah thanks to 3 points by Christine Bestland (2G-1A). Cornell's Emily Fulton had both goals to give her 23 on the season. Unfortunately for Cornell (24-5-2), Lakers goalie Amanda Makela made 29 saves and came through when needed to end the ECAC champion's season for the second straight year.
ECAC runner-up Clarkson (29-5-5) advanced to its first-ever Frozen Four with a 3-1 win over Boston College (27-6-3). Senior goalie Erica Howe made 23 saves, only allowing a late power play goal by Dana Trivigno with 3:45 remaining. Vanessa Gagnon scored twice for the Golden Knights and Patty Kazmaier finalist Jamie Lee Rattray had two assists Saturday.
Mercyhurst and Clarkson played twice this season. The Lakers took the season series, winning 2-0 and tying 1-1.
