LAWRENCE, Kansas (Ticker) -- It was a perfect final game at Allen Fieldhouse for Nick Collison and Kirk Hinrich.
Collison scored 24 points and Hinrich added 19 as seventh-ranked Kansas continued its tradition of winning on Senior Day with a 79-61 Big 12 Conference victory over No. 17 Oklahoma State.
Kansas (22-6, 12-2 Big 12) maintained first place in the Big 12 race heading into road games at Texas Tech and Missouri. The day was reserved for Collison and Hinrich, a pair of Iowa natives who helped lead the Jayhawks to the Final Four last season. The two were honored before the game and gave senior speeches afterward.
"On media day, I talked about something that I hope the people around the league should appreciate Kirk and Nick for turning down the money, the quick money and coming back to play college basketball," Kansas coach Roy Williams said. "They should appreciate the kind of kids they are on the court and off the court."
The Jayhawks have won 20 straight games on Senior Day.
"I was so worried about about my speech, that I thought I might not play well," Hinrich said. "I just tried to focus on the game and that kept me in it mentally."
Collison also grabbed 16 rebounds for his 10th double-double and Hinrich had five assists. Even Oklahoma State coach Eddie Sutton hugged the two players, who helped hand Sutton his worst home loss last season by an identical score, 79-61.
"I think that those two guys represent the University of Kansas in such a class manner," Sutton said. "I think they are the type of people that all of us would like to recruit. They have just had a remarkable career."
The Jayhawks took command with a 19-5 spurt that provided a 28-15 lead with 6:27 left before halftime, triggered by Collison's three-point play. The Cowboys (20-7, 9-5) managed only two baskets in a six-minute span.
Collison scored seven points in a 9-2 surge after halftime that opened up a 59-42 advantage with 12:20 remaining.
The efforts of Collison and Jeff Graves, who grabbed 10 rebounds, allowed Kansas to hold a commanding 54-34 cushion on the glass. The Jayhawks grabbed 15 offensive rebounds and scored 11 second-chance points.
"The main thing thing just play good hard, sound fundamental defense," Williams said. "It was a heckuva basketball game, just a hard-fought game."
Keith Langford was the only other player on double figures for Kansas with 12 points. The Jayhawks turned in a sloppy effort with 23 turnovers, including seven by point guard Aaron Miles.
Kansas has won 28 out of its last 30 Big East games and can win its second straight Big 12 title by sweeping its final two games.
"This year, we have hit some bumps, but we improved along the way," Hinrich said. "If we are to win our next few games, I will be very impressed with the season and another Big 12 title."
Oklahoma State dropped for the sixth time in nine games, shooting only 36.5 percent (23-of-63). The Cowboys fell into a tie with Missouri for fourth place in the Big 12. Tony Allen led Oklahoma State with 21 points and Victor Williams added 18. Allen also came up with four steals
