ROCHESTER, N.Y. -- Junior goaltender Ali Binnington made a season-high 42 saves, including 20 in the third period, as Rochester Institute (8-5-1, 4-0-1 CHA) extended its Division I team-record unbeaten streak to five games with a 2-1 win against No. 10 Mercyhurst (7-5-2, 2-2-1 CHA) at Ritter Arena on Friday afternoon.

Kolbee McCrea scored a pair of first period goals for the Tigers, who defeated the Lakers for the first time in five meetings. It is also the first time RIT has defeated a nationally-ranked opponent. Morgan Scoyne assisted on both RIT goals, while Kourtney Kunichika and Lindsay Grigg also drew assists.

The two goals for McCrea give her 50 in three seasons. She becomes the ninth player in the program history to score 50 in a career.

Binnington was tremendous for the Tigers, especially in the third period, when Mercyhurst out-shot RIT 20-9. She made a tremendous pad save on a tip-in attempt by Emily Janiga with just 15 minutes left, then robbed Bailey Bram in front 20 seconds later.

Binnington is now 8-3-1 in 2013-14 with a 1.88 goals against average and .935 save percentage. In her last seven games, Binnington is 6-0-1 with a 0.85 goals against average and .966 save percentage.

Mercyhurst pulled goaltender Amanda Makela with 1:35 left and had a 5-on-3 advantage for 1:15 and ended with a 6-on-4. Binnington and the RIT penalty-killing unit did a tremendous job blocking shots all game. Overall, RIT blocked 24 shots, including a team-high eight by Grigg.

Mercyhurst outshot RIT 43-24. The Lakers were 1-for-6 with the man-advantage, while RIT was 1-for-8.

No. 5 Quinnipiac 1, St. Lawrence 1

HAMDEN, Conn. -- Both goalies were on their game on Friday as No. 5 Quinnipiac and St. Lawrence played to a 1-1 tie from High Point Solutions Arena. In their first meeting since the Saints knocked the Bobcats out of the 2013 ECAC Hockey Quarterfinals, play was up-and-down at a furious pace but each team's goalie was up to the task throughout. The Bobcats put 47 shots on the Saints' goalie Carmen MacDonald but only one snuck through while junior goalie Chelsea Laden stonewalled 24-of-25 shots to help Quinnipiac walk away with one point. Quinnipiac extends its unbeaten streak to eight games, improving their record to 10-1-4 (3-1-3 ECAC Hockey) while St. Lawrence moves to 5-7-1 (4-2-1 ECAC Hockey).

Laden was a pivotal player for the Bobcats as the Saints made her work hard for all 24 of her saves on Friday. The nation's leader in goals against average lowered her season total to 0.94, allowing just 14 goals in 15 appearances this season. Her pads were busy on the evening, especially in the overtime period where she turned away five brilliant scoring opportunities for the Saints.

No. 6 Harvard 3, No. 9 Boston University 1

CAMBRIDGE, Mass. -- In a top-10 showdown at Bright-Landry Hockey Center on Friday, it was No. 6 Harvard that came away with a thorough 3-1 victory against crosstown foe No. 9 Boston University. The Crimson (7-1-1, 6-1-1 ECAC) had three different goal-scorers over the course of the game, and got 34 saves from sophomore goaltender Emerance Maschmeyer, who earned her sixth win of the year.

The Crimson was able to skate away with the 3-1 win at home. For the first time in four games, Harvard outshot its opponent, firing 35 shots to BU's 32. But the Harvard defense, which was a perfect 4-for-4 on the penalty kill, kept the Terriers in check.

No. 8 Clarkson 7, Princeton 0

PRINCETON, N.J. --  Four first-period goals guided eighth-ranked Clarkson by Princeton 7-0 on Friday afternoon.

The win propels the Golden Knights to 11-3-2 (4-2-1 ECAC Hockey), and they pick up two important points on the road. The loss sends the Tigers to 5-3 (4-3 ECAC Hockey) and Clarkson jumps over Princeton to take possession of fifth place in the conference.

Clarkson wasted no time getting on the scoreboard, as 29 seconds into the game senior Vanessa Gagnon finished passes from classmates Jamie Lee Rattray and Brittany Styner, and beat Princeton goaltender Kimberly Newell for her fourth goal of the season to put the Green and Gold up 1-0.

Just 2 minutes later, the Knights struck again as Styner received passes from Rattray and sophomore Erin Ambrose for her fifth goal on the year to double Clarkson's lead to 2-0.

Continuing her dominant first 5 minutes of the game, Rattray added a goal to her pair of assists as she took a pass from Ambrose and beat Newell to give Clarkson the 3-0 lead. The goal was Rattray's team-leading 10th on the year.

Still in the first period, freshman defender Corie Jacobson notched her second goal of the year at the 16:53 mark with help from sophomore Shannon MacAulay to give the Golden Knights a commanding 4-0 first period lead.

Senior goaltender Erica Howe earned her sixth shutout on the year and moves her into sole possession of first place in the country.

Gagnon and MacAulay would add goals in the third period to reach the final score of 7-0. MacAulay's goal was a power-play goal, the first for the Knights in more than three games. Rattray led the Knights with five points on the afternoon (1-4-5) and Styner added three points, including her team-high 14th assist.

Clarkson outshot Princeton 43-14 on the afternoon, and the Knights' front line of Rattray, Gagnon and Styner were all plus-five on the day. The Knights took more shots in the first period (19) than Princeton did throughout the entire 60 minutes.
