Washington ? Georgetown fans surged on the court at the buzzer, celebrating a victory that evoked the Hoyas’ powerhouse days of John Thompson and Patrick Ewing – an 87-84 victory over No. 1 and previously unbeaten Duke.

The Blue Devils (17-1) never have been 18-0, and paint-defending, layup-producing Georgetown wasn’t about to let it happen Saturday, despite J.J. Redick matching his career high of 41 points for Duke.

With surprisingly easy backdoor moves and open three-pointers, the unranked Hoyas shot 61 percent, built a double-digit lead deep into the second half and nervously survived the frantic final minutes to preserve the upset.

Brandon Bowman scored 23 points, and Jeff Green had 18 for the Hoyas (12-4), who had lost nine straight against ranked opponents and hadn’t beaten a No. 1 team since an 85-69 victory over St. John’s on Feb. 27, 1985. The victory marks the first defining moment for the school under coach John Thompson III, son of the Hall of Fame coach who guided the Hoyas for more than two decades.

“We’ve come close, we’ve been there, we’ve been at the other end of some lopsided defeats,” said Thompson III, in his second season since replacing Craig Esherick. “And for that group to win this game, for that group to experience that, is special.”

Tennessee 80, No. 2 Florida 76

Taurean Green missed a long three in the waning moments for Florida.
