It is back to the Frozen Four for the two-time defending National Champion Clarkson University after a thrilling 2-1 overtime victory against Boston College in NCAA quarterfinal action at Cheel Arena on Saturday afternoon.

The Golden Knights, who played in three extra-session games in last year's run to their third NCAA Title, got the game-winner from a familiar source to win their 19 straight game in the postseason.

Sophomore Elizabeth Giguere (Quebec City, QUE) found a loose puck at the top of the crease during a scramble in front and knocked in the winner at 14:38 of overtime. Giguere tallied the gamewinner in overtime of last year's National Championship game 2-1 victory over Colgate. She also scored the deciding goal in the extra session of last year's 2-1 triumph over Mercyhurst in the 2018 national quarterfinal at Cheel.

Giguere, who has 11 game-winners in her brief collegiate career, also tallied the overtime-winning goal in the 4-3 Game 2 victory over Quinnipiac in the ECAC Hockey quarterfinals on March 2.

Giguere's goal against Boston College was set up by assists from junior center Michaela Pejzlova (Pardubice, Czech Rep.) and senior defenseman Emma Keenan (Calgary, ALB).

Trailing 1-0 late in the third, Clarkson tied the game on a great individual rush by senior defenseman Josiane Pozzebon (Bourget, ONT). Pozzebon took a pass from senior Cassidy Vinkle (Belleville, ONT) at the BC blueline and skated around a couple of Eagle defenders, cut to the net and flipped in her sixth goal of the season with 3:03 remaining in regulation.

Boston College got the early jumped with a goal from last year's Patty Kazmaier winner Daryl Watts, who redirected a shot from the top of the right circle at 13:24 for her 22nd goal of the season.

Boston College outshot the Green and Gold 36-30, but graduate student Kassidy Sauve (Whitby, ONT) was on top of her game, making 35 saves, including six in overtime.

Clarkson was 0-of-3 on the power play, while Boston College went scoreless on its lone man-advantage of the game.

Unbeaten in its last eight games (7-0-1), the Knights have reached 30 wins for the fourth consecutive season. Clarkson will face off against Wisconsin in the semifinals of the Frozen Four next Friday at Quinnipiac University in Hamden, CT.
