A three-goal third period proved to be the difference on Saturday afternoon, as the No. 5 St. Lawrence women's hockey team won a top 10 battle against No. 10 Cornell 5-2 in a game that featured a power play goal, a 6-on-4 shorthanded empty net goal and an extra attacker goal.

The win is the first for the Saints against Cornell in Appleton Arena since Jan. 18, 2008, and it gives St. Lawrence a 19-3-2 overall record and 11-2-1 mark in conference play this season. Cornell falls to 13-6-2 and 9-3-2 in ECAC Hockey.

Kennedy Marchment led the Scarlet and Brown with the game-winning goal and three assists, while linemates Hannah Miller and Brooke Webster each scored a goal and added two assists of their own.

St. Lawrence got off to a slow start against the Big Red, registering just four shots on goal in the first period — all of which came in the final three minutes of the frame. But sophomore goaltender Grace Harrison made nine of her 28 saves in the first period and the teams were scoreless heading into the second.

"That was really what we needed today," head coach Chris Wells said. "Cornell really took it to us and had us pinned in all first period. We fought hard and got out speed back and it turned into a very entertaining game."

With the Saints on the power play late in the second period, Webster collected the puck beneath the red line and played it to the front of the net where it was kicked forward by Marchment to sophomore Justine Reyes in the left circle. Reyes' initial shot was saved by Cornell netminder Paula Voorheis, but the Chino Hills, California, native fought around a defender to get another shot off the rebound and beat Voorheis high for her ninth of the year and a 1-0 St. Lawrence lead.

With 22 seconds remaining in the second period Marchment and Webster moved into the Cornell zone on a two-on-one with Webster beating Voorheis with a one-timer from the bottom of the left circle for a 2-0 lead.

Cornell cut the lead in half with a shorthanded tally from Kristin O'Neill just 19 seconds into the third period, but Marchment and the Saints responded with the eventual game-winning goal in transition just over two minutes later.

On a three-on-two, Webster took a shot from the left side which Marchment was able to tip past Voorheis as she cut through the middle for her team-leading 15th goal of the year and 99th career point.

Cornell coach Doug Derraugh got aggressive in the latter half of the third period, pulling Voorheis with the Big Red on the power play with 9:14 to play to set up a 6-on-4 opportunity for the visitors. But Marchment fed Miller for a shorthanded empty-net breakaway goal to extend the Saints lead to 4-1 just 25 seconds into it.

Minutes later, he pulled Voorheis against with Marchment in the box for checking and this time it paid off as Kaitlin Doering was able to beat Grace Harrison high on the blocker side for Cornell's second and final goal of the night.

Nadine Edney netted her third goal of the weekend at the 15:21 mark on a solo effort in the defensive zone; battling on the wall, forcing a turnover and then tucking the puck under Voorheis from just outside the crease for the eventual 5-2 margin.

"We executed some real nice plays and battled hard all night. Those are two very important points," Wells added.

Cornell finished with a 30-26 shot advantage on Saturday afternoon. Voorheis made 21 stops for the Big Red.
