The North Dakota State University Bison led a parade of several upsets and a record four overtime games highlighted second round play at the NCAA men's basketball tournament.
The Bison, a 12 seed, upset Oklahoma 80-75 in overtime in the West region. It's the first-ever NCAA tournament victory for the Bison from Fargo. Lawrence Alexander hit a 3-pointer with 11 seconds left to force overtime and freshman Carlin Dupree scored four points in the final 75 seconds to seal it. Alexander hit for a career-high 28.
Cameron Clark led Oklahoma with 25.
Harvard, another 12 seed, got 11 points from Siyani Chambers, including five straight in the final two minutes of a 61-57 upset of fifth-seed Cincinnati. Wesley Saunders scored 12 for the 27-4 Crimson who didn't trail after the opening minutes of the game. Harvard becomes the first Ivy League school with NCAA tourney wins in consecutive years since Princeton in 1983-84.
Harvard was another dangerous No. 12 seed. In 27 of the last 30 NCAA tournaments, the 12th seed has knocked off a five seed.
Cincinnati got 18 points from Sean Kilpatrick and finished 27-7.
