With the loss, Harvard fell behind Princeton in the all-time series, 34-33-7.
"We've been playing well but luck just hasn't gone our way," Petruccelli said. "We just have to keep our heads up and try to get the young guys prepared for next year."
Although any chance of finishing atop the Ivy standings is now out of Harvard's reach, many members on the team feel that they can still get a lot out of the season through a strong finish, especially with three of its last five games against conference rivals.
"We're just going to do the best job we can and try to end the Ivy schedule strong," Hench said.
"A lot of freshmen and sophomores have shown that they can step up recently," Kelly said. "They've been able to gain confidence that'll be really helpful next year."
Harvard travels to Fairfield on Tuesday for a late-night match before returning home for a showdown with Dartmouth at noon on Saturday at Ohiri Field.
"Even though we're out of the running for the Ivies, we're not giving up," Kelly said. "A lot of the league games coming up are old rivalries that still mean a lot."
