LAWRENCE — Jalen Wilson had 20 points, Kevin McCullar Jr. added 16 points and 13 rebounds, and No. 8 Kansas avenged a loss to Kansas State just a couple of weeks ago with a 90-78 victory over the seventh-ranked Wildcats on Tuesday night.
Dajuan Harris Jr. scored 18 for the Jayhawks (18-4, 6-3 Big 12), who built a 12-point halftime lead before coasting to their 17th straight home win over the Wildcats in the 10th matchup of top-10 teams in series history.
Kansas has rebounded nicely from a rare three-game skid that included the overtime loss to Kansas State, and made sure to avoid taking back-to-back losses in its storied home for the first time since the 1988-89 season.
Markquis Nowell scored 23 points and Keyontae Johnson had 22 to lead the Wildcats (18-4, 6-3), who were trying for their first regular-season sweep of their biggest rival in four decades. Nae'Qwan Tomlin added 11 points and David N'Guessan had 10.
In their first meeting on Jan. 17, the Wildcats raced to a big early lead and controlled the game until late in the second half, when the Jayhawks forced overtime — only for Kansas State to win on Johnson's alley-oop dunk.
It was the Jayhawks who controlled the rematch.
They used a 16-7 run in the first half that included a technical foul on Kansas State coach Jerome Tang to build a 32-19 lead. And when Johnson answered with eight straight points for the Wildcats, and the lead was eventually trimmed to four, the reigning national champs pulled away again down the stretch.
It was 37-32 when Wilson hit back-to-back 3-pointers and Zach Clemence added one of his own. And by the time Wilson made two foul shots with about 10 seconds left, Kansas had built a 49-37 lead that it took to the break.
The Wildcats briefly got within six in the second half before the Jayhawks stretched their lead to as many as 16.
OFFICIATING OOPS
Johnson had to sit with two fouls just 2 1/2 minutes into the game. Only problem? The crew of John Higgins, Kip Kissinger and Marques Pettigrew gave one to the wrong player. By the time they corrected their mistake, the Wildcats' leading scorer had unnecessarily ridden the bench for several minutes.
SELLOUT ... AND THEN SOME
For the first time in more than 15 years, more Kansas students redeemed tickets than there was space available inside Allen Fieldhouse. The overflow had to watch the game on screens in the adjacent Horejsi Family Athletics Center, where the Jayhawks play volleyball games. Those students also got refunds and concessions vouchers.
BIG PICTURE
Kansas State's three losses in league play have been to ranked teams on the road: TCU, Iowa State and Kansas. And with a more forgiving second half to the Big 12 schedule, the Wildcats remain firmly in the conference title hunt.
Kansas got its mojo back with its win over Kentucky last weekend. This victory over another bunch of Wildcats was crucial because the road doesn't get any easier for the Jayhawks, who are in the midst of three straight games against teams ranked 13th or better.
