Alando Tucker scored a game-high 23 points and Kammron Taylor knocked down four 3-pointers, but it wasn't enough as Indiana knocked off the second-ranked Badgers, 71-66, Wednesday at the Assembly Hall.
UW fell for the first time on the road and had to suffer the indignity and foreign feeling of watching the Indiana fans storm the court after the victory.
"It's like watching your girlfriend go out with another guy right in front of you," junior guard Michael Flowers said of having to watch the post-game mosh pit. "It hurts. It hurts the heart."
Indiana (16-5, 6-2 Big Ten) got 20 points off the bench from A.J. Ratliff and 16 points from D.J. White to end the nation's longest winning streak at 17 games. The Hoosiers remain undefeated at home this season (12-0) and have won 14 in a row on Branch McCracken Court dating back to last year. Indiana shot nearly 63 percent in the second half and knocked down 5-of-6 three-pointers to erase a two-point halftime deficit and hand Wisconsin (21-2, 7-1 Big Ten) its first loss in conference play. Ratliff was the killer for the Badgers, who scored 18 of his team-high 20 points in the second half.
"I felt somebody had to step up and make plays," Ratliff said. "I was opening up and I had all the confidence in the world."
"He stepped up, he really stepped up when they needed plays and he got hot," said Tucker.
Taylor was 4-of-9 from three-point range to counter for Wisconsin, but his teammates combined to shoot 1-of-11 from behind the arc. Taylor finished with 15 points.
Tucker had 14 points on 6-of-10 shooting in the first half. That following a 17-point performance in the first half against Iowa on Sunday. He and Taylor combined to score 20 of Wisconsin's 28 first-half points.
Despite seven turnovers in the first seven minutes, the Badgers jumped out to an early 13-7 lead. An 8-0 run put Indiana back in front and Earl Calloway gave IU a 17-14 lead with a jumper at the seven-minute mark of the first half.
Tucker answered on the other end by splitting the Hoosiers' 2-3 zone for an easy layup. Then, following an IU miss, Taylor hit Tucker with a baseball pass to the other end of the court that led to a breakaway layup and a three-point play.
Wisconsin scored the final five points of the half and Jason Bohannon's jumper from the left elbow with three seconds left gave the Badgers a 28-26 halftime lead.
Both offenses got hot in the second half, but nobody was hotter than Ratliff. The IU guard scored 18 second-half points and finished one shy of his career high.
Ratliff began and ended an 11-0 Hoosier run with 3-pointers. A third 3 by Ratliff gave Indiana a 53-43 lead with just under 10 minutes left to play. It marked just the second time this season that Wisconsin has trailed by double digits.
A quick timeout by the Badgers was followed by eight consecutive points on four Wisconsin jumpers. Taylor hit back-to-back treys and tied the game at 59-59 with 4:50 left to play.
"Our guys did a heck of a job to come back, down 10 on the road like that," head coach Bo Ryan said.
Ratliff scored the next five points and Indiana made four free throws to lead 68-63 with 1:38 remaining. Taylor hit his fourth 3 to pull the Badgers within two, but that would be UW's final points.
"I liked some of our looks down the stretch," Ryan said. "We were playing from behind, that part of it, we haven't had a lot of experience with. Then again, you have to remember how Indiana's been playing here and what they're doing now. This is going to be a tough place for other people to come into."
Ratliff hit another jumper on the other end to seal the win. Wisconsin shot 50 percent in the second half, but couldn't get over the hump against Indiana. The Badgers missed three 3's in the final 20 seconds and the Hoosiers walked away with the win. It marked just the eighth time under coach Bo Ryan that Wisconsin lost a game it was winning at the half.
