It was a night many Harvard fans felt might never come.

After 10 straight losses to Princeton and 27 defeats in the last 28 meetings between the two teams, the Crimson (8-11, 3-3 Ivy) erased the memory of a long series of frustrations by beating the Tigers 61-57 Saturday evening at Lavietes Pavilion.

“It feels great,” captain Jason Norman said, “I’m just so happy right now. I can’t even really describe it.”

The two teams found themselves locked at 50 with 2:15 to play, following a tense second-half battle that saw four ties and eight lead changes. After junior center Brian Cusworth tipped in senior point guard David Giovacchini’s missed layup to give the Crimson the lead, junior forward Matt Stehle drew a crucial charge on Princeton guard Will Venable. What could have been a game-changing three-point play for the Tigers turned into a backbreaking turnover, and Harvard seized the momentum to hold on for the victory.

“Everybody on the bench had a lot of confidence that we were going to pull this out,” Norman said. “Determination down the stretch got us this victory.”

Harvard held a six-point advantage at halftime, but Princeton (10-8, 1-3) quickly erased that deficit with a 10-2 burst after the break to take a 32-30 lead with 16:07 to play.

A three-pointer by guard Scott Greenman, his fourth of the night, gave Princeton a four-point lead—its largest lead of the second half—with 5:40 showing on the clock.

The Crimson, however, refused to go away, and ran off a 6-0 run to retake the lead for good. Harvard maintained its resolve down the stretch, hitting 7-of-8 free throws in the final 40 seconds to seal the victory.

“That’s the experience,” senior guard Kevin Rogus said. “We kept our composure, and were able to fight back and do what we needed to do.”

Harvard was led by the long-range heroics of Rogus, who hit five treys and finished with 17 points—a night after he was smothered by Penn’s man-to-man defense. Rogus and sophomore guard Jim Goffredo, who came off the bench for 10 points, were able to get free and spot up behind the arc against Princeton’s zone.

“The zone helped the ball move a little bit better,” Harvard coach Frank Sullivan said. “[Rogus] just felt more comfortable and made some big shots.”

Princeton started the game looking very businesslike after its shocking loss to Dartmouth on Friday night, and—after a series of crisp offensive sets yielded several layups and open threes—held a 14-9 lead with 10:32 to play. But Rogus checked in from downtown to halt a 7-2 Tigers run, igniting the capacity crowd of 2,030, and sending Harvard on a hot stretch that would see it grab a 28-22 halftime lead.

Harvard’s strong perimeter play was crucial in light of Princeton’s smothering interior defense. The strong-armed tandem of post men Judson Wallace and Mike Stephens held Stehle and Cusworth to just nine shots combined.

“[When a team] tries to focus too much on one area, the other area opens wide up,” Cusworth said. “And Kevin did a great job stepping up with the fact that they were collapsing on Matt and I.”

While Rogus provided the spark, the entire team pounded the boards all night long, keying the Crimson’s upset. Harvard out-rebounded the Tigers 29-17, and also grabbed nine offensive boards—none bigger than Giovacchini’s follow of his own missed shot with 1:11 to play, which he then dished to Cusworth, who stuffed it home for a 54-50 lead.
