AMES, Iowa (AP) – 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.
