GREENSBORO, N.C. --—It's been a long, historic run for Lehigh.
It just got a little longer Friday night.
C.J. McCollum scored 30 points and the Mountain Hawks converted their last six free throws to become the sixth No. 15 seed to win against a No. 2 seed, second in a three-hour span Friday.
"Well, I want to congratulate Lehigh," Duke coach Mike Krzyzewski said. "They had the best player on the court tonight in McCollum.
"They were very bold the entire game. They were bold throughout and bold won."
Lehigh (27-7) plays the Notre Dame/Xavier winner Sunday in the round of 32. Duke's season ends at 27-7.
Lehigh led for the majority of the game and fought off several Duke runs, the last of which was a 7-0 spurt to take a 49-47 lead with 8 minutes, 36 seconds left.
Mackey McKnight's 3-pointer from the right wing gave the Mountain Hawks the lead for good 16 seconds later.
And, despite a few shaky moments in the closing moments, the Hawks made enough free throws to win their first NCAA Tournament game in five tries.
"Lehigh is a really good team and McCollum is a heckuva player," Krzyzewski added. "He's one of the best players in the country.
"But all of their kids played well."
Gabe Knutson's dunk with 47 seconds left gave Lehigh a 67-59 cushion, but a couple of missed free throws and an Austin Rivers two free throws had Duke down just three with 28 seconds left.
Lehigh, as it had all night, regrouped from adverse moments with the poise of champions.
Jordan Hamilton's dunk off a three-quarter pass from McCollum pushed the lead to five and Knutson rebounded a Duke miss, was fouled and made two free throws to restore a seven-point cushion.
Quinn Cook's trey with one second left made sure Lehigh had to get the ball inbounds one more time against Duke's frantic pressure.
The Hawks did and McCollum, who missed two freebies with 36 seconds left, made both to secure the third win by a Patriot League team in the NCAA Tournament. Bucknell won a game each in 2005 and '06.
"Though not in games in the tournament, we've played in some tough environments and we've always just played off the crowd," senior Jordan Hamilton said, referring to games earlier this season at Iowa State and Michigan State.
"We appreciate the North Carolina fans supporting us."
