No. 1 Wisconsin (36-2-2) broke a 2-2 tie with 48 seconds remaining in regulation as senior Meghan Duggan powered the Badgers past Boston College, 3-2, in the semifinal round of the 2011 NCAA Women's Frozen Four at Tullio Arena in Erie, Pa., Friday night.

Duggan set up sophomore Brianna Decker's  nation-leading 12th game-winning goal to finish the game with a three-point performance. The Badger captain and Patty Kazmaier Memorial Award finalist scored UW's first goal of the game and assisted the Badgers' other two tallies.

Junior Hilary Knight also recorded multiple points against the Eagles. Her two assists marked her 200th and 201st career points. In addition, Decker earned an assist in the game before scoring the deciding goal for a two-point effort.

Freshman Alex Rigsby made 23 saves to improve to 26-1-2 with the win. Meanwhile, Boston College goaltender Molly Schaus recorded 43 saves on 46 shots, falling to 24-5-4 with the loss.

The Badgers outshot Boston College 46-25 in a game that saw 13 penalties. Both teams were able to capitalize on one power-play opportunity as the Badgers went 1-for-7 with the man-advantage while the Eagles converted one of their four opportunities.

Wisconsin got on the board first as Duggan solved Schaus at the 4:23 mark of the first period. Senior Mallory Deluce fed the puck to Knight, who fired a shot on goal. Schaus made the save, but the attempted clear by BC came out to Duggan high in the slot where she was able to beat Schaus five-hole for the goal.

UW extended its lead to 2-0 midway through the period when junior Brooke Ammerman capitalized on the power-play. Duggan passed the puck down low to Decker, who found Ammerman on a centering pass in front of the net, and she buried the Badgers’ second goal of the night.

Boston College (24-7-6) scored the lone goal in the second period as Blake Bolden scored an unassisted goal on the power play. Bolden got control of the puck on a quick transition and beat Rigsby to trim UW’s lead to one with 11:21 remaining in the second period.

Midway through the third period, Boston College tied the game at 2-2 on an impressive individual effort by Taylor Wasylk. The Eagles’ rookie gained control of the puck in the neutral zone and maneuvered around UW’s defensemen before flipping the puck past Rigsby for the tying goal at 11:23 of the third.

With an overtime period looming, both teams had several chances over the final 10 minutes, but Decker who decided the game as she scored with just 48 seconds remaining to give Wisconsin the 3-2 lead. Knight fed the puck up to Duggan whose initial shot was saved by Schaus. The puck rebounded off Schaus’ pads and Decker buried the game-winner.

The win marked the Badgers’ 36th of the season, tying the program’s single-season win record (2006, 36-4-1; 2007, 36-1-4). Duggan also extended her mark on the UW record book, breaking the program record for points in a single season at 86 points.
