BURLINGTON, Vt. — Taylor Willard's power play goal with 1:08 remaining in the third period gave the Catamounts the 3-2 lead and eventual victory over the defending national champions and third-ranked Golden Knights.

Vermont improves to 5-6-1 overall and remains 3-4-1 in Hockey East play while Clarkson falls to 10-2-1 and 3-1-0 in ECAC play. The victory is Vermont's first-ever win over a team ranked in the top-3 nationally, Previously, Vermont had beaten two fourth-ranked teams in the 2009-10 season, defeating Clarkson in October and knocking off New Hampshire in February.

"This is the team I knew we had all along," Head Coach Jim Plumer said. "I have been talking about us focusing on the details, learning to play smart, simple hockey, and to take advantage of the opportunities when they're given. We put it together for 60 minutes against an excellent hockey team in Clarkson. I hope we take that same mentality into every game for the rest of the season."

The Catamounts struck 8:20 into the first period. After gaining control in the Golden Knight zone, Ali O'Leary dished the puck to Alyssa Gorecki at the top of the circle, and with space, Gorecki fired a wrist shot through traffic and over Shea Tiley's left pad. Alyssa Holmes also picked up an assist on the play.

Vermont entered the first intermission leading 1-0. Sydney Scobee made 11 saves and the Catamount defense blocked four shots. UVM's killed both penalties in the frame.

Just over a minute into the second period, Clarkson's leading scorer Loren Gabel could not finish on the odd man rush. Scobee made a fantastic save with her right pad to keep the Golden Knights off the board. The Catamounts had multiple high quality scoring chances on their first power play of the period following a holding penalty on Emma Keenan, but were unable to beat Tiley and expand their lead.

Clarkson's Michaela Pejzlova scored two power play goals in less than four minutes to give the Golden Knights a 2-1 advantage with 7:52 remaining in the middle frame. The first goal came following quick puck movement by Clarkson, and the second came on a rebound during a 5-on-3 Clarkson advantage.
