Ohio, which had a losing record in conference play but won the Mid-American Conference, upset third-seeded Georgetown with a convincing 97-83 victory in the Midwest Regional at Providence, R.I.
Armon Bassett scored 32 points as the 14th-seeded Bobcats won in the NCAA tournament for the first time in 27 years.
Ohio Coach John Groce wouldn't call it the biggest win in team history.
"I certainly think it's one of them," he said. "What it does more than anything is it gives belief in our guys in what we're doing."
Ohio seized the lead early on its three-point shooting and never had a serious letdown. The Hoyas made a small run in the second half that cut a 19-point lead to seven, but D.J. Cooper made a three-pointer and the Bobcats cruised from there.
Kansas 90, Lehigh 74: The top-seeded Jayhawks hung in and survived a scare before pulling away for a win over the scrappy 16th-seeded Mountain Hawks at Oklahoma City.
Marcus Morris scored 26 points and Sherron Collins had 18 as Kansas fell into its season-long pattern of playing in spurts.
Northern Iowa 69, Nevada Las Vegas 66: Ali Farokhmanesh hit a three-pointer from the wing with 4.9 seconds left to lift the ninth-seeded Panthers past the eighth-seeded Runnin' Rebels at Oklahoma City.
Northern Iowa hadn't won a game in the NCAAs since upsetting third-seeded Missouri in 1990.
Tennessee 62, San Diego State 59: Melvin Goins made his fourth three-pointer with 19 seconds left after the Aztecs cut the deficit to one point, and the sixth-seeded Volunteers held off 11th-seeded San Diego State at Providence.
The Aztecs' Kawhi Leonard scored 12 with 10 rebounds, but he missed a well-guarded three-pointer at the buzzer that would have tied it.
