Kalil then rolled right and pushed a shot past Lions keeper Molly Starsia-Lasagna, who had come up to contest the shot, for a 1-0 lead.

Columbia's Nikki Campbell notched the equalizer off a penalty corner with 8:46 remaining, but Nagle and Kalil responded quickly, scoring a pair in the next 5:27.

Nagle redirected a low, hard shot by freshman midfielder Kalen Ingram off a penalty corner with 5:53 remaining, and Kalil outmaneuvered her defender and Starsia-Lasagna two minutes later, chipping a shot into the bottom right corner of the cage while falling into the circle to make it 3-1.

Sophomore back Sarah Luskin closed the scoring with 17:06 remaining in the second half, as her first career goal came after she picked off a clearing pass on the left side of the circle and flipped it into the cage.

"Columbia is so much improved from the last time we played them," Kalil said. "[Harvard Coach Sue Caples] feels teams like this are dangerous because they're scrappy and they play like they have nothing to lose. They did play hard, and being such a young team, we got a little complacent. Their goal should never have been scored. That was a breakdown."

Harvard 5, UNH 4 (OT)

Nagle's goal 5:12 into the first overtime session capped a late four-goal rally and gave the Crimson a surprising come-from-behind win against No. 14 UNH.

"It came off a restart," Nagle said. "I just tried to get my stick on it to tip it, and it trickled in. It had just enough on it to get past the goalie."
