LAWRENCE, Kan. -- Now that Missouri has bid farewell and joined the Southeastern Conference, a new archrival is emerging for Kansas. Its name is Iowa State.

The 223rd consecutive sellout in historic Allen Fieldhouse was definitely louder for the Cyclones on Monday night than it was two days earlier when Kansas State came calling.

When the No. 8 Jayhawks got hot in the second half and raced to an 89-76 victory over the 11th-ranked Cyclones team that handed them a road loss the month before, the windows seemed to rattle in this 60-year-old arena.

Wayne Selden Jr., who scored 19 of his 20 points in the second half, admitted he had been "haunted" by the 86-81 loss back on Jan. 17.

The pain persisted "that day, that whole next day. Maybe a little bit after," Selden said. "We had to get onto the next (game). But a sense of urgency came back when we knew we had them next."

Selden, after missing all three of his shots and scoring only one point in the first half, drilled four of his first five 3-pointers after intermission, often finding himself virtually unguarded on the right wing, as the Jayhawks (19-3, 8-1 Big 12) padded their lead in the Big 12 race to 1 1/2 games.

Georges Niang had 24 points for Iowa State (16-5, 6-3), which dropped out of a second-place tie with West Virginia.

Making sure to give Kansas State plenty of respect, Kansas coach Bill Self agreed the Cyclones, at least for now, are quicker than just about anyone else to get Jayhawks blood boiling. The Cyclones were gunning for their third straight victory over Kansas.

"I think it's cyclical. But right now, for sure," Self said. "Right now, the way it sits, K-State would be our biggest rival, but you could make a case that Iowa State has emerged as our other rival. Certainly the last couple of years, without question."

Despite success at home in the Big 12 tournament against Kansas in recent years, the Cyclones have lost 10 straight in Allen Fieldhouse.

"What has Bill lost in this building, nine times?" Iowa State coach Fred Hoiberg said. "It's tougher than hell to walk out of this building with a win."

Leading 35-28 after a seesaw first half, the Jayhawks reeled off a 14-6 run the first 4 minutes, 45 seconds after intermission, with Selden scoring eight points, including two uncontested 3-pointers. Iowa State called timeout and tried to regroup after Selden's second 3-pointer put Kansas on top 49-34. But unable to stop Kansas' transition game, the Cyclones never got the lead under nine points.

"Selden was great," Hoiberg said. "You have to take your hat off to him. He hit some tough shots. He hit a couple where I didn't think our urgency was good enough."

Perry Ellis's three-point play gave the Jayhawks breathing room at 77-63 with less than three minutes left. Ellis had 17 points and Kelly Oubre Jr. had 16 for the Jayhawks, who are gunning for their 11th straight Big 12 title.

Bryce Dejean-Jones had 14 points for Iowa State, and Monte Morris had 12.

Niang's steal and Jameel McKay's dunk sliced the lead briefly to single digits at 54-45, but Kansas scored the next seven points, four on Oubre's baskets and three on a shot by Selden, who was 5-for-7 from behind the arc.
