Royce White had 18 points and nine rebounds as Iowa State upset fifth-ranked Kansas 72-64 on Saturday, snapping the Jayhawks' winning streak at 10 games.
Melvin Ejim added 15 points for the Cyclones (15-6, 5-3 Big 12), who had lost 13 straight to Kansas since their last victory in 2005.
White, a 39 percent free thrower shooter in Big 12 games, hit a pair to put Iowa State up 64-59 with 1:47 left. Kansas threw the ball away and Chris Babb drained a 3 to give the Cyclones an eight-point lead with 55.6 seconds left.
Tyshawn Taylor led five players in double figures with 16 points for Kansas (17-4, 7-1), which hadn't lost since Dec. 19 against Davidson. Thomas Robinson had 13 points, but he committed five turnovers and the Jayhawks were outrebounded 36-23.
Iowa State students celebrated the biggest win of coach Fred Hoiberg's tenure by storming the floor.
This was Kansas' toughest true road test of the year so far — and it ended with the Jayhawks' first true road loss of the season.
Kansas caught the Cyclones napping to start the second half and took its biggest lead to that point, 45-39, thanks to an 11-0 run. But big man Anthony Booker brought Iowa State back, sinking a rare 3-pointer to put the Cyclones ahead 50-49 with 12:13 left.
Neither team could get much going over the next 6 minutes, but Tyrus McGee's three-point play gave Iowa State a 56-53 lead with just over 6 minutes left. Robinson then blew an open dunk and White hit two layups — one a reverse he spun off the glass — to make it 60-55 Iowa State with 3:42 left.
White also had five assists, and Scott Christopherson finished with 14 points for the Cyclones.
Iowa State fed off the energy of its second sellout crowd of the year and jumped on the Jayhawks early.
Booker drilled a 3 and Babb followed with a steal and layup that put Iowa State ahead 19-11, prompting Kansas coach Bill Self to call timeout.
Kansas finally took a 31-29 lead on an impressive scoop through traffic from Taylor with 3:31 left before the break. Iowa State rallied to grab the halftime advantage, 37-33, despite committing 13 turnovers in the first 20 minutes.
The Cyclones led in part because of their defense on Robinson. He was 1-of-6 shooting in the first half and traveled three times trying to free himself up for shots in the paint.
Kansas certainly knew what Iowa State was capable of after the Cyclones threw a scare into the Jayhawks in Lawrence two weeks ago.
Iowa State led at halftime back on Jan. 14 and pushed its lead to as many as 12 points before Kansas stormed back for an 82-73 win. The Cyclones might have been able to pull off that upset had they shot better than 2 of 15 from 3-point range in the second half.
Iowa State didn't let the opportunity pass by this time around — and it now has a marquee win that will look great on its resume come March.
