Freshman center Greg Ostertag scored five points on two-of-two shooting. Both shots were 15-footers.
"Coach Robinson (Steve) has been working with me on my outside shot," Ostertag said. "He tells when I'm shooting slop and when I'm shooting good. It felt good tonight.
"I'll be shooting those jump shots. I feel I can shoot from 15 feet."
In addition, Ostertag helped defend Marquette's Jim McIlvaine. The Warriors' 7-1 sophomore scored 15 points on five-of-five shooting.
"I went up against him in 1989," said Ostertag of the Racine, Wis., native. "Our teams were in the finals of the Las Vegas Tournament. I outscored him 8-4."
Coach Kevin O'Neill, whose Warriors lost to KU by 37 last year in Lawrence, was again impressed with the Jayhawks.
"They took it to us in every way," said O'Neill. "Foul trouble hurt us but they did, too."
KU outrebounded Marquette 32-17. Alonzo Jamison and Adonis Jordan had six apiece for KU. Jordan had eight assists, and Rex Walters finished with four steals.
KU is now 6-0 on the road. Marquette has lost six of its last eight games.
