The Tigers pulled ahead, 4-3, on a long wrister, but Harvard continued fighting for the equalizer.

Throughout the third period, each of the Crimson lines brought high energy, putting the puck on net 12 times.

Eventually, the persistence paid off, as forward Alex Killorn redirected a puck into the net with about five minutes remaining to tie the game at four.

Starting in net for Harvard was senior Kyle Richter, who proved to be effective, keeping the Crimson in the game when Princeton attempted to pull away. With less than a minute left, Richter made a critical game-saving stop that sent the contest into overtime.

In the extra period, both teams had a number of chances, but neither side could break through. Richter made another important save on a wraparound attempt with less than a minute remaining in the extra period.

Though the crowd was anxious for a definite outcome, they left the rink having seen one of Harvard’s most competitive ECAC matches of the season.

After the game, both Donato and forward Killorn mentioned that rebounds were something that the team has focused on in practice.

“It’s not just the number of shots,” Donato said. “It’s really being able to get second and third opportunities and getting some of the goals in the dirty areas, the areas that are tough to play in around the net.”

This emphasis on second chance opportunities allowed Harvard to stay competitive against one of the better teams in the conference.

“I thought our guys really battled,” Donato said. “We feel like we are a team that has improved tremendously over the last couple months.”
