LAWRENCE, Kan., Jan. 25 (UPI) -- Salim Stoudamire poured in 20 of his career-high 32 points in the second half Saturday as the top-ranked Arizona Wildcats rallied from a 20-point deficit for a stunning 91-74 victory over No. 6 Kansas, which had a 25-game home winning streak snapped.
Arizona (15-1) looked lethargic and uninspired in a mistake-filled first half. The Wildcats had 10 turnovers midway through the period and Kansas took its largest lead at 44-24 on Keith Langford's dunk off an alley-oop with 5:41 left to play.
Jason Gardner's two free throws pulled the Wildcats within 52-39 at halftime. Arizona then used stifling defense to take command with a 23-5 run to open the second half, grabbing a 62-57 lead on Gardner's layup with 13 minutes remaining.
"In the first half, Kansas just did an unbelievable job defensively," Arizona Coach Lute Olson said. "We didn't go to the offensive glass. In the second half, we hit the boards, we took care of the ball and we hit shots."
Kansas (13-5) missed its first seven shots of the second half and shot 29 percent over the final 20 minutes. The Jayhawks were a sizzling 65 percent in the first half.
"It's impossible to figure out, much less explain it," Kansas Coach Roy Williams said. "I thought the first half we were sensational. It was a total breakdown and it is hard to say, but the second half had to be my worst nightmare and at the same time it had to be the worst coaching job I have ever done in my entire life."
Kirk Hinrich's three-pointer cut the deficit to 81-74 for Kansas with 2:18 remaining. The Wildcats got back-to-back three-pointers from Rick Anderson and Stoudamire for a 13-point cushion and were on their way to a 10th straight victory.
Gardner scored a season-high 23 points and Anderson finished with 15 points for Arizona, which posted its first victory at Allen Fieldhouse. The Wildcats settled down and had just seven turnovers in the second half.
"The number one team was not on the floor in the first half, I'll guarantee you that," Olson said. "I like out togetherness and our toughness (to come back)."
Stoudamire was on target throughout and nailed six three-pointers and 12 of 18 shots overall. Arizona was also solid at the foul line, shooting 85 percent.
"He's one of the leaders on the team," Gardner said. "He stepped up and hit some big shots. I feel like he's the best shooter in the country."
Langford scored a career-high 27 points and Collison chipped in 17 for Kansas, which committed 10 of its 17 turnovers in the second half. The Jayhawks have lost consecutive games for the second time this season.
It was Kansas' first loss at home since a 79-71 defeat to Iowa State on Feb. 17, 2001. They also saw a 23-game non-conference home winning streak end. Iowa was the last non-Big 12 team to win in Lawrence, posting an 85-81 victory on Dec. 8, 1998.
The Jayhawks seemed to respond to Wednesday's 60-59 loss at Colorado early. A layup by Aaron Miles on the fast break established the first double-digit lead for Kansas at 22-12 with just over 13 minutes left in the first half.
Langford's dunk that made it 44-24 ended a 9-2 spurt as Kansas had the fans screaming early. But Gardner converted a layup as Arizona scored seven straight points to get back in the game.
"It's a great atmosphere," Arizona forward Luke Walton said. "In the first half, they jumped on us, but we fought back and got the win."
Kansas made just two of 14 from beyond the arc in the second half after hitting six of 10 in the first half.
