Final Stats | VIDEO: Coach Freeman Recaps The Win

HANOVER, N.H. -- Junior Gabby Kozlowski had two goals and one assist and scored the game-winner as the Columbia field hockey team outplayed Dartmouth on all three lines en route to a 4-2 win Saturday at Chase Astroturf Field.

Columbia (7-6, 4-1 Ivy League) also received goals from sophomore Danielle Cosentino and senior captain Carson Christus in the win and junior goalkeeper Christie O'Hara tallied a game-high nine saves. Kozlowski now has 30 career goals and moved into second place on the Columbia's all-time scoring list

The win puts the Lions in a tie with Princeton for first place in the Ivy League as Dartmouth (8-6, 3-2 Ivy League) drops down the standings. Yale could join both Columbia and Princeton tomorrow with a win over Penn.

"We knew Dartmouth was going to be an emotional Ivy battle today," Columbia head coach Marybeth Freeman said. "I am proud of the way we remained poised and maintained composure throughout the course of the match. Our defensive unit was solid and Christie O'Hara was a commanding presence in goal. Our midfielders used their speed well and our forward running lines put us in position to capitalize on our upfield opportunites."

Forwards Kozlowski and Christus kept the pressure on Dartmouth (8-6, 3-2 Ivy League), pushing the ball up and combining for eight of Columbia's 18 shots and three of the team's four goals.

Midfielders Paige Simmons and Danielle Cosentino had good possessions and also applied pressure up front, combining for seven shots.

The Columbia defense was stellar against a Dartmouth squad that featured two of the top 30 scorers in the nation in Kelly Hood and Ali Savage. Christus and the strong backline group Desi Scherf, Lauren Skudalski, Katie DeSandis and Bridget DeSandis (who had a defensive save in the game) thwarted the Big Green's offensive possessions and held Dartmouth to just four penalty corners, making it difficult for the no. 15 offense in the nation to find clear shots at the goal. O'Hara was a sharp as ever and has now made nine or more saves in five of the 11 games she has played in this year.

Dartmouth struck first as Savage scored her 11th goal of the season off an assist from Lisa Masini at the 1:38 mark.

Cosentino scored her second goal of the season at 6:47 to knot the game at 1-1. Junior Bridget DeSandis came up with a big assist to set up a rebounded score for Cosentino.

Kozlowski made the go-ahead score at 21:45, marking her 29th career goal and ninth of the season. Simmons assisted on the goal after ripping a pass toward the goal for Kozlowski to corral. Kozlowski's 30th career goal came at the 30:49 mark after she worked the ball through the defense herself for an angled shot at the goal.

Down by two goals at halftime, Dartmouth came out of the break more aggressive with 13 second-half shots. The Big Green drew to within 3-2 seven minutes into the second half when Sam Anderson tapped in a loose ball in front of a crowded Columbia net.

The Lions responded 20 seconds later off a penalty corner when Christus drilled a redirected pass from Kozlowski  for Columbia's fourth goal of the game at 42:29.

O'Hara and the Columbia defense stood their ground for the remaining 27 and a half minutes, denying Dartmouth the opportunity to climb back. O'Hara's and Christus' leadership and tenacity shined in the Lions' big win against one of the toughest offenses in the nation.

Dartmouth had 19 shots to Columbia's 18, but 13 of those came in the second half when the Big Green was trying to dig their way out of a two-goal or three-goal deficit. The Lions outperformed Dartmouth on penalty corners, 12-4.

Kozlowski led all players with five points (two goals, one assist) and recorded her first multi-goal game since the Lions's 4-2 win over La Salle on Sept. 4.

The Lions will continue to take it one game at a time as the look to build upon their three-game winning streak against a tough Lafayette squad on Tuesday in Easton, Pa. The game is Columbia's  final regular-season road game of the year and is scheduled for a 5:30 p.m. start. Columbia's next home game is on Friday, Oct. 28, at 6 p.m. against Ivy League rival Yale.
