Kansas' Udoka Azubuike dunked seven times and scored 24 points as the 14th-ranked Jayhawks put the hurt on Stanford, 75-54, in a nonconference men's basketball contest Thursday night at the Golden 1 Center in Sacramento.
Kansas (10-2) had eight dunks and six 3-pointers in the first half alone while shooting 62.5 percent.
Okpala hit a 3-pointer during his second time on the court and finished with six points in 28 minutes.
Michael Humphrey had 20 points and seven rebounds for the Cardinal (6-7) as Stanford coach Jerod Haase faced his former school where he starred from 1995-97 under then-Kansas coach Roy Williams.
Azubuike upped his season dunk total to 49, shot 12 for 15 and came into the game ranked second in NCAA Division I field-goal shooting percentage.
"It's the nicest building I've ever been in. I've never been in a building nicer than this," Kansas coach Bill Self said. "It kind of felt like a home game."
The Jayhawks are 10-3 in the series but had lost two of the last three, winning 89-74 last Dec. 3 at Allen Fieldhouse. Stanford beat Kansas in the 2014 NCAA Tournament to reach the Sweet Sixteen.
The Cardinal weren't bothered by the pro-Kansas crowd.
"We want to play in arenas like this," Reid Travis said. "That gave us energy coming into the game I just wish we could have sustained it a little more."
Travis, Stanford's leading scorer, dealt with foul trouble and was held to a season-low 12 points after coming in with a 22.2 scoring average.
"I was a little disappointed in myself not having more success finding guys and still attacking that pressure," Travis said. "We're disappointed. We feel like we had a great game plan in place."
The Cardinal, who faced its third ranked opponent this season, dropped to 0-11 against AP Top-25 teams during Haase's two seasons.
Stanford hasn't beaten a ranked opponent since topping No. 11 Oregon on Feb. 13, 2016, at Maples Pavilion.
Stanford hosts California on Dec. 30 to open Pac-12 competition.
