Derrick Byars and Shan Foster each scored 24 points, and Vanderbilt snapped the nation’s longest winning streak by upsetting the Gators, 83-70, after they finally fell into a hole they couldn’t dig themselves out of Saturday.

“This is one for the ages,” Byars said. “Twenty years from now, I’ll be able to tell my little kids this. This is special. You can’t explain it.”

Florida (24-3, 11-1) had won 17 straight games and needed a victory to clinch at least a share of the SEC’s Eastern Division and the overall league title. They also had won seven straight against the Commodores.

But Vanderbilt (18-8, 8-4) has been one of the country’s best against ranked opponents this season. Students poured onto the court at Memorial Gym after the Commodores pulled off their first victory over a top-ranked team since Jan. 13, 1993, when they beat then-No. 1 Kentucky, and their sixth victory over a ranked team this season.

“A lot of people don’t ever get the opportunity to play the No. 1 team in the country,” Foster said. “We got the opportunity and seized the moment.”

The Commodores won for the seventh time in nine games by beating the nation’s best shooting team at its own game, outshooting the Gators 57.1 percent to 44 percent from the field. They took the lead in the first half and led by as much as 16 points late.

“We caught them on an afternoon where they missed shots they normally make,” Vandy coach Kevin Stallings said.

Florida coach Billy Donovan tried to put the loss into perspective by pointing out his Gators, the defending national champs, had won 35 of their last 37 games and had not lost a game since Dec. 3 to Florida State. That said, he didn’t want this to be the start of a trend.

“We don’t want one to lead to two,” Donovan said.

This was the fourth time this season the Gators trailed by double digits. They came from 18 down Wednesday night before beating Alabama.

“We never want to get down like we have been,” Florida guard Lee Humphrey said. “It seems like the last few games we’ve gone into halftime down. It’s never what we want to do. We want to stay focused and come back. Today Vandy, they kept playing well. They outplayed us the second half.”

Ross Neltner added 15 points for the Commodores.

Joakim Noah led Florida with 15, and Corey Brewer and Al Horford each had 13 as the Gators had a season-high 22 turnovers.

The Gators had been shooting 53.7 percent, but they struggled from the start when they hit only two of their first nine shots. They last led midway through the first half. 13-12, on a pair of free throws by Horford.

Vanderbilt led 35-27 at halftime, the second-fewest first-half points scored by Florida this season.

It was a fast-paced, up-and-down game from the opening tip. With 12 minutes left, Byars stole the ball and drove for the Commodores. Brewer stole it back under the Gators basket, but Florida turned it right back over.

No. 3 Wisconsin 75, Penn State 49

Madison, Wis. – Alando Tucker shook off a slow start and scored 22 points to lead Wisconsin. Tucker was just 1-for-6 in the first half, his only points from the field a three-pointer that allowed Wisconsin (26-2, 12-1 Big Ten) to go into the half up 36-25. But he scored 12 of his 16 second-half points during a 22-6 run.

Geary Claxton led Penn State (10-15, 1-11) with 15 points.

No. 4 North Carolina 77, No. 21 Boston College 72

He also missed a three when it was 75-72 with 10 seconds left, and Lawson hit a pair of free throws with seven seconds remaining to ice it.

No. 5 UCLA 81, No. 19 Arizona 66

Josh Shipp tied a career high with 24 points for UCLA, which defeated Arizona for the fifth straight time. The Bruins scored the game’s first six points and never trailed. Leading 35-34 at halftime, the Bruins hit eight of 15 three-pointers in the second half to take command of the game.

No. 7 Pittsburgh 65, Washington 61

Pittsburgh – Levance Fields and Ronald Ramon made two free throws each in the final 1:40 to prevent Pittsburgh from being defeated at home for the second time in six days, and the Panthers held off despite an ineffective game from star Aaron Gray. The 7-foot Gray was limited to five points to match his season low.

No. 8 Memphis 78, Gonzaga 77, OT

Spokane, Wash. – Chris Douglas-Roberts hit a layup with 5.6 seconds remaining in overtime as Memphis edged Gonzaga for its 15th straight victory.

The Tigers (23-3) led 76-75 on Jeremy Hunt’s three, but Hunt fouled Abdullahi Kuso with 17.6 seconds left and Kuso sank both to put Gonzaga up 77-76.

Gonzaga’s Jeremy Pargo hit a jumper with a minute remaining in regulation to tie it at 69-69 after the Bulldogs trailed most of the way.

No. 11 Nevada 79, Northern Iowa 64

Reno, Nev. – Kyle Shiloh scored all 16 of his points in the final 20 minutes. Marcelus Kemp scored 18 points, Nick Fazekas 17 and Ramon Sessions 14 for the Wolf Pack (24-2, 11-1 Western Athletic Conference), who have won 17 of their last 18 and are now 59-6 at home since the start of the 2003-04 season.

Eric Coleman had 16 points and Grant Stout 10 for the Panthers (16-11, 7-9 Missouri Valley Conference), who led at the half 33-32 but now have lost five in a row and eight of their last nine.

No. 12 Marquette 61, Louisville 59

Milwaukee – Jerry Smith hit a three-pointer as time expired to lift Louisville past Marquette. Smith, a freshman, scored all nine of his points on three-pointers in the final 3:04 as Louisville (19-8, 9-4) took sole possession of third place in the Big East.

No. 16 Southern Illinois 68, No. 13 Butler 64

Indianapolis – Jamaal Tatum scored 20 points, and Southern Illinois stopped No. 13 Butler’s 22-game home winning streak. Matt Shaw added 15 points for the Salukis (24-5), who defeated a ranked team on the road for the first time since December 1975 against then-No. 16 Michigan.

No. 14 Georgetown 58, Villanova 55

Philadelphia – Jeff Green scored 19 points and hit the game-winner with 19.8 seconds left. Green had a career-high eight blocks, sealed the win with two free throws in the final seconds and helped the Hoyas (20-5, 10-2) move into a tie with Pittsburgh for the Big East lead.

Stanford 88, No. 15 Oregon 69

Stanford, Calif. – Brook Lopez scored a career-high 26 points and keyed a big second-half run that helped Stanford beat Oregon for the 21st consecutive time at Maples Pavilion.

No. 25 Alabama 72, No. 20 Kentucky 61

Tuscaloosa, Ala. – Richard Hendrix had 16 points and nine rebounds, and Alabama fought off several rallies, handing the Wildcats their third straight loss.

The Crimson Tide (19-7, 6-6 Southeastern Conference), who had lost two straight, never trailed and scored the game’s final seven points to avoid blowing a big lead for the second straight game.

No. 23 West Virginia 81, Seton Hall 71

Morgantown, W.Va. – Frank Young scored seven of his 18 points during a key second-half run to help West Virginia beat Seton Hall.
