Kevin "Yogi" Ferrell scored 25 points to lead host Indiana to a stunning 75-72 upset over previously unbeaten Wisconsin on Tuesday night.
The third-ranked Badgers (16-1, 3-1 Big Ten) were trying to become the first team ever to win 13 straight games over the Hoosiers (12-5, 2-2).
Wisconsin started the night as one of Division I's four remaining unbeaten teams and it looked like it would stay that way when the Badgers took a 10-point lead with 13:27 to play.
But the Hoosiers, playing their best game of the season, answered with 12 straight points to take a 54-52 lead with 9 minutes left.
Indiana led 70-65 with 2:03 remaining but still had to fend off Wisconsin's late challenge. Ferrell made two free throws with 18.3 seconds left to give Indiana the three-point lead and both of Wisconsin's potentially tying 3-pointers came up short.
Traevon Jackson led the Badgers with a career-high 21 points.
The hometown fans stormed the court after Indiana prevented Wisconsin from by winning its sixth in a row in Bloomington.
Wisconsin did not play its usual brand of mistake-free basketball. It turned the ball over 10 times and went just 1 of 4 from the free-throw line.
No. 7 Florida 72, Georgia 50: Michael Frazier II scored a career-high 21 points as host Florida (14-2, 3-0 SEC) set a school record for consecutive home wins.
The undermanned Gators won their 25th straight at the O'Connell Center, topping the previous mark set between March 2006 and November 2007. Two-time national champions Corey Brewer, Taurean Green, Al Horford and Joakim Noah were on those teams.
This team has four seniors who have lost in three straight regional finals.
Frazier made 7 of 16 shots, including 5 of 12 3-pointers.
Marcus Thornton led Georgia (8-7, 2-1) with 11 points and seven rebounds.
Kansas State 72, No. 25. Oklahoma 66: Marcus Foster scored 18 points and Nino Williams made four free throws in the closing seconds.
Shane Southwell added 16 points for the host Wildcats (13-4, 3-1 Big 12), who rallied from a 62-56 deficit with a little more than 5 minutes left to play.
Ryan Spangler had a career-high 21 points and 14 rebounds, and Buddy Hield scored 12 points for Oklahoma (13-4, 2-2), but it wasn't enough to offset a lousy night by Cameron Clark. The Big 12's leading scorer was held to two points, hitting just 1 of 9 shots. He was stripped of the ball with 24.5 seconds left and the Sooners trailing 67-64.
No. 5 Wichita State 72, Bradley 50: Fred VanVleet had 22 points and seven rebounds and host Wichita State remained undefeated.
Darius Carter added 11 points for the Shockers (18-0, 5-0 Missouri Valley Conference), who extended their school record for a winning streak.
After overcoming a 19-point, second-half deficit in its last game, Wichita State took any mystery out of this game pretty quickly.
Asbury 54, Indiana Southeast 52: Smothering defense held down two high-scoring teams.
Visiting Asbury, held to 31 points less than its season average, hit 14 of 19 free throws in the second half. Annissia Woods scored 10 points and had 11 rebounds for the winners, now 14-3. Ellie Steiner had 11 points.
Transy woman honored
Transylvania senior Madisen Webb was named Heartland Collegiate Athletic Conference women's player of the week after the first triple- double of her career.
The senior guard got 16 points, 12 assists, and 10 rebounds as the Pioneers beat Hanover on Wednesday. Then she first-place Transy to its 11th straight win with 12 points, four rebounds, and five assists against Manchester.
Webb leads the league in assists and free-throw shooting.
