POTSDAM, N.Y. -- A goal in the opening minute of the game allowed the sixth-ranked Clarkson to manage a split against the fourth-ranked North Dakota by the final score of 2-1 on Saturday afternoon at Cheel Arena.

The win improves the Golden Knights to 13-4-2 (5-2-1 ECAC Hockey) while the loss drops North Dakota to 10-4-2 (7-3-2 WCHA).

Clarkson got on the board almost immediately, as the Knights pressured the North Dakota net and scored 23 seconds into the game. Senior Vanessa Gagnon found classmate Brittany Styner in front of the net. Styner attempted a shot but could not get a clean look and senior Jamie Lee Rattray was there to put the puck in the net for her 13th goal of the season, giving the Knights the early lead.

North Dakota outshot Clarkson 26-17 on the afternoon but failed to score on any of their six power-play attempts.

In one of the more physical and engaging games of the season, both the Crimson (9-1-2, 7-1-1 ECAC) and Eagles (12-4-2, 7-1-0 WHEA) combined for 88 shots by the end of overtime, the most Harvard has seen all season.

No. 9 Boston University 4, Minnesota-Duluth 2

BOSTON -- Sophomore Sarah Lefort scored two goals and added two assists to help lead the ninth-ranked Boston University to a 4-2 win against Minnesota-Duluth on Saturday afternoon at Walter Brown Arena.

BU (14-3-1) staked itself a 4-0 lead to help secure its fourth consecutive victory. Lefort logged her third consecutive three-point game and has tallied four points in two of the last three contests. The Terriers finished 2013 with a 16-0-0 record at Walter Brown Arena, including a 7-0-0 mark this season.

Four other skaters collected an assist, including freshmen Natalie Flynn and Samantha Sutherland. Juniors Caroline Campbell and Shannon Stoneburgh each had a helper as well.

Freshman Victoria Hanson earned her first non-conference victory thanks to a career-high 33 saves. She stopped 12 shots in the final frame and helped the Terriers kill off all eight of Minnesota-Duluth’s (7-8-3) power-play chances.

No. 10 Robert Morris 4, Rochester Institute 2

PITTSBURGH -- Robert Morris head coach Paul Colontino earned his 50th career win this afternoon as the Colonials defeated Rochester Insitute in College Hockey America (CHA) play 4-2.

No. 10 Robert Morris (16-3-1, 8-1-1 CHA) extends its unbeaten streak to nine games and improves its winning streak at 84 Lumber Arena to six games. The Colonials also stayed undefeated on Saturdays (8-0-0) with the victory.

Both goaltenders faced plenty of shots in a scoreless first period. Making her sixth-consecutive start, freshman netminder Jessica Dodds made 13 saves in the first 20 minutes, which is the second most the rookie has stopped in a period behind a 14-save third frame in a 3-2 win against Mercyhurst on Nov. 9. Both RMU and RIT (9-9-1, 4-3-1 CHA) earned two power plays in the period, but couldn't capitalize on the man advantage.

The sweep of RIT was RMU's first since the 2007-08 season. The Colonials were 0-4-1 in their previous five meetings with the Tigers prior to this weekend.
