Harvard was using a very limited part of the field in the first half, Caples said, and not passing well.

But Harvard came out poised in the second half. The Crimson started to use its exceptional passing game to its advantage by using a greater width of the field than it had in the first and placing its forwards better by putting them higher up on the field. The team also put more pressure on the Penn defense by stepping up closer on Penn's 16-yard hits.

The offense responded too, outshooting the Quakers 14-4 and earning 17 corners to Penn's one in the second half.

Although Harvard came out strong in the second, Penn scored first, a little less than two minutes into the half, to make it 1-0 on Bills' third of the season, assisted by Courtney Martin and Ken Murray.

At 22:19, taking Penn's goal as a wake-up call, Harvard finally turned one of its offensive drives into a goal. Nagle finished off a shot from freshman forward Philomena Gambale by lifting the ball above Penn goalkeeper Alison Friedman, who was sprawled out on the ground after saving the initial shot.

With the game tied 1-1, the Crimson seemed only to get to get more aggressive. At 20:26, Kalil scored what would end up being the game-winner. Taking a rebounded shot that sophomore midfielder Eliza Dick passed her way, Kalil pushed the ball under the goalie's pads for her 18th point of the season, best on the team.

"I think a defender ran in front of the goalie and screened her so she couldn't see the ball," Kalil said. "Then I just tapped it in."
