The Harvard men’s basketball team is thankful that Dave Klatsky is no Kyle Wente.

Klatsky missed two free throws and a last-second, desperation three-pointer at the end of overtime, allowing Harvard to upset Penn, 78-75, for the second straight year at Lavietes Pavilion on Saturday night.

“I give Harvard a great deal of credit,” Penn Coach Fran Dunphy said. “They played well, they were ready to go, and they out-toughed us. [Junior guard] Patrick Harvey was terrific.”

Against the up-tempo Quakers (10-4, 1-1 Ivy), the Crimson (10-6, 3-1) was energized by a remarkable performance from Harvey, who netted a career-high 28 points and reeled off a personal 15-point run in the waning moments of the second half to keep Harvard in the game.

The previous night must have seemed like déjà vu for Harvard as the Crimson dropped another heartbreaking, two-point loss at the hands of the defending Ivy champion, Princeton (6-7, 2-0).

Unlike last year’s game, in which the Tigers needed Wente’s 25-foot heave for the win at the buzzer, on Friday it was the Crimson trailing, with a chance to win on the game’s final possession. Junior forward Sam Winter, though, was unable to hit a runner in the lane and Harvard ended up on the losing end of the 50-48 decision.

For the second straight year, two points are all that separated the Harvard men’s basketball team from sweeping the Ivy League’s perennial powers for the first time since 1987. Last year, a stunning 77-62 upset of Penn was followed by the heartbreaking 69-67 loss to Princeton.

Harvard, by virtue of a sweep over Dartmouth, leads the league with three wins. The Crimson’s 10 overall wins mark its seventh straight season with double-digit wins, setting a school record. The Crimson players now break for exams and return to the court next to host Brown and Yale in two weeks.

After falling behind by eight points early in the second half, the high-powered Quakers offense reeled off 14 straight points to establish their largest lead of the game at 51-45 with 10:39 left.

Just when it looked like the Crimson would lose control of the game, Harvey decided to do Penn’s run one better.

The 5’11 marksman knocked down two three-pointers, hit three of his patented runners, and completed a three-point play to account for 15 consecutive Harvard points in a stretch of six minutes.

The Harvey run counteracted Penn’s earlier surge and left the Crimson on top, 60-59, with less than four minutes in the game.

Following two Winter free throws, Penn stopped the bleeding when forward Koko Archibong nailed a clutch three-pointer to knot the game at 62 with 2:54 left to play.

Drew Gellert, Harvard’s resilient captain, responded with a driving lay-up on the ensuing possession to give the Crimson a tentative 64-62 lead with two and half minutes remaining.
