Tim Frazier hit a floater in the lane with 8 seconds left and Jermaine Marshall blocked Sam Maniscalco's layup at the buzzer to give Penn State a 54-52 upset of No. 22 Illinois on Thursday night.

Frazier finished with 12 points and nine assists for the Nittany Lions (10-10, 2-5 Big Ten), who ended a 3-game losing skid.

Off a timeout, Frazier drove at the top of the key before Jon Graham's pick freed him from hounding defender Brandon Paul.

The Illini (15-4, 4-2) lost for the first time since re-entering the AP Top 25 this week. They had a short stay atop the Big Ten as the league's lone one-loss team in conference play.

Paul had 20 points to pace the Illini, while Meyers Leonard added 15.
