Jessica Wong scored late in the third overtime to lift Minnesota Duluth to a 3-2 victory over Cornell in the NCAA Women's Frozen Four championship game in Minneapolis.
Wong redirected a shot by Tara Gray in front of the Cornell net and the puck trickled past Big Red goaltender Amanda Mazzotta, ending the longest title game in college women's hockey history.
Minnesota Duluth (31-8-2) won its fifth national title in the 10 years that the NCAA has awarded a women's hockey championship.
Mazzotta finished with 61 saves for Cornell (21-9-6).
After a scoreless first period, the Big Red used a second-period power play to take the first lead. The Bulldogs killed 35 seconds of a 5-on-3, but Cornell defender Lauriane Rougeau blasted a shot from the blue-line that hit traffic in front, deflecting past Bulldogs goaltender Jennifer Harss.
Mazzotta stopped the Bulldogs' first 17 shots, but just 18 seconds into the third period Emmanuelle Blais scored a power-play goal.
Blais' initial shot was blocked by Rougeau, but the Bulldogs leading scorer got hold of the puck on rebound and snapped a rising shot past Mazzotta's glove for a 1-1 tie.
Blais was the tournament's most outstanding player.
The teams traded goals late in the third period, with Jaime Rasmussen giving the Bulldogs a 2-1 lead with a power-play goal. Cornell answered two minutes later when Melanie Jue lifted a backhander past Harss during a scramble in front of the net.
Minnesota Duluth was making its sixth Frozen Four appearance, having hosted the tournament twice and winning the NCAA title in 2001, 2002, 2003 and 2008.
Cornell was skating in its first Frozen Four, and seeking its first national title in a women's sport.
Harss finished with 49 saves for the Bulldogs.
