Lawrence, KS (SportsNetwork.com) - Wayne Selden netted 19 of his 20 points in the second half and No. 8 Kansas defeated No. 11 Iowa State 89-76 on Monday night.
Perry Ellis posted 17 points and six rebounds and Kelly Oubre Jr. added 16 points and five boards for Kansas (19-3, 8-1 Big 12), which had dropped its last two games against Iowa State. It was the first time the Jayhawks had lost two in a row to the Cyclones since a five-game slide from Feb. 1999-Feb. 2001.
"K-State would be our biggest rival, but you could make a case that Iowa State has emerged as our other rival," KU coach Bill Self said.
Georges Niang tallied 24 points, six boards and five assists for the Cyclones (16-5, 6-3), who had won four of their last five games coming in.
"It's tougher than hell to walk out of this building with a win," Iowa State coach Fred Hoiberg said.
The Cyclones held a 22-21 edge following Monte Morris' layup at the 5:54 mark of the first half before Kansas closed the frame on a 14-6 run.
Oubre knocked down consecutive 3-pointers during the surge, which was capped on an Ellis layup for a 35-28 margin heading into the break.
The margin swelled even more over the final 20 minutes.
Another 14-6 run to begin the second half had the Jayhawks up 15. Selden netted the final eight points of the burst, wrapping triples around a jumper for a 49-34 Kansas cushion with 15:24 to play.
After Jameel McKay's tip-in clawed Iowa State within 54-45, an 13-3 Jayhawks swing put the game away. Frank Mason potted a jumper to jumps-tart the flurry and hit another one during the run to help KU jump out to a 67-48 spread with 6:34 remaining.
