NEW YORK – The Dartmouth women’s lacrosse team suffered its first loss of the 2017 season Sunday at Columbia in the Ivy League opener for both teams.

The Big Green dropped to 4-1 overall with the 17-10 loss, while the Lions earned their first-ever win against their Hanover counterparts in 20 all-time meetings (1-19), improving to 3-1 in doing so.

Senior Courtney Weisse scored three times with sophomores Kierra Sweeney and Elizabeth Mastrio notching a pair of goals each.

Columbia was led by a five-goal game from Laine Parsons and four each from Taylor Quinn and Lindsey Ewertsen.

Freshman goalkeeper Kiera Vrindten made nine saves, while being dealt her first collegiate loss. The Lions were anchored on the defensive end of the field by the play of goalkeeper Kelsey Gedin and her 10 saves and just 10 allowed.

Dartmouth once again was dominant on the draw control, winning 18-of-29 in the game, but was outshot 36-24 and committed a season-high 25 turnovers.

Half of those 18 draw controls came thanks to sophomore Kathryn Giroux, who already has the single-game record of 10 set earlier this season and now has a nine-draw game as well.

After a stellar start to her Dartmouth career, Sunday marked the first loss for first-year head coach Danielle Spencer.

The Big Green will have a break for exams and will return to action on Friday, March 17 when they play host to the University of Southern California at Scully-Fahey Field. Opening draw is set for 3 p.m.
