Marcus Morris scored 23 points and grabbed nine rebounds, twin brother Markieff added 19 points and 10 boards and No. 3 Kansas moved into a tie for first place in the Big 12 by beating slumping Oklahoma 82-70 on Saturday.
The Jayhawks (27-2, 12-2) shot 57 percent, making more than half of their shots from the field for the 21st time this season, and notched their seventh straight win in the series.
Kansas opened a double-digit lead in the opening 8 minutes and led by at least 10 points for the final 27 minutes but struggled to put away the Sooners (12-16, 4-10), who lost their seventh straight game.
Cade Davis led Oklahoma with 19 points and Andrew Fitzgerald scored 16.
The Sooners were simply no match for the loaded Jayhawks, who lead the nation in shooting at 52 percent and were even hotter early on.
Kansas even got a boost in its hopes for a seventh straight Big 12 regular season title when No. 5 Texas squandered a 22-point lead and lost 91-89 at Colorado.
Jayhawks fans provided about half of the crowd, and many stuck around to cheer when Texas' game went final.
Making just his third career start, freshman Tyler Neal helped Oklahoma stick with the hot-shooting Jayhawks for a few minutes by hitting two of the Sooners' three early 3-pointers. But Kansas just kept connecting.
Elijah Johnson, Marcus Morris and Josh Selby all hit 3s during a 13-2 burst that put the Jayhawks up 23-13 and Kansas hit 17 of its first 22 shots to build a 17-point lead in the first half.
Oklahoma got within 45-35 on Davis' layup to start the second half as Kansas finally missed three consecutive shots, but then the Jayhawks pushed the accelerator again.
The Morris twins combined to score the first six points of an 11-0 run that extended Kansas' lead, and the Sooners could never really challenge after that.
Davis converted a three-point play and a four-point play in a span of three possessions, and his three free throws got Oklahoma within 75-64 with 4:24 to play but that's as close as it got.
Tyrel Reed scored 11 points for the Jayhawks, who dominated the boards 35-16 behind the Morris twins.
Freshman Cameron Clark had 10 points for Oklahoma.
