POTSDAM, N.Y. – Colgate's only lead of the game was the only one that mattered.

Megan Sullivan scored a rebound goal just 1:18 into overtime to lift the No. 5/5 Raiders to a 4-3 victory over No. 2/2 and defending national champion Clarkson Friday night.

Colgate never led until the finish but answered every Clarkson goal with a goal of its own in a see-saw affair. The Raiders got the break they needed when Clarkson's Loren Gabel was penalized for checking with three seconds left in regulation.

That meant the Raiders were on the power play for nearly two minutes to begin overtime, and Colgate took advantage to deal the Golden Knights their first loss of the season and first loss at Cheel Arena in 13 games dating to last season. The Raiders win also snaps Clarkson's 24-game unbeaten streak dating back to Jan. 20, 2017.

The Raiders controlled the puck for the entirety of overtime but it took more than a minute for the winning chance to make itself available. Olivia Zafuto fired on net from the point and Clarkson's Ella Shelton made the block.

But the puck caromed directly left to Sullivan, who had nothing but netting in front of her. The senior didn't miss and scored her third goal of the season, officially at 1:18 of the overtime session.

The Raiders scored in each of the three periods of regulation, tying the score every time. Bailey Larson(Sycamore, Illinois) found the net at the 13:00 mark of the first period for her third goal of the season.

Annika Zalewski scored her first of the year, this one on the power play, to make it 2-2 at 6:24 of the second. And then Malia Schneider tied it for the third and final time when she scored a power-play goal 1:22 into the third.

For Schneider, it was her fifth goal of the season to move into second place on the team in that category.

Julia Vandyk and the Raider defense held the defending champs scoreless the rest of the way to earn Vandyk her second win of the year in as many starts. The junior registered 22 saves.
