STILLWATER, Oklahoma (Ticker) -- Tony Allen helped make coach Eddie Sutton's 1,000th game a success.
On the night Sutton reached a milestone, Allen scored 17 points as 12th-ranked Oklahoma State posted a 63-55 Big 12 Conference victory over Kansas State.
Sutton, who is in his 13th season with the Cowboys, improved his record to 290-116 at the school. He tied Gene Bartow for 16th place on the all-time list for games coached.
Sutton did not make a big deal out of reaching his milestone, saying, "It means I've coached a long time."
In a typical defensive struggle for the Cowboys, Allen provided the offense, making 6-of-10 shots from the field and all four of his foul shots.
Melvin Sanders added 14 points Oklahoma State (18-2, 7-1 Big 12), which bounced back from Saturday's loss at then-No. 3 Texas that snapped a 15-game winning streak.
Matt Siebrandt netted 17 points for the Wildcats (11-9, 2-5), who have lost three straight and five of their last six games.
It looked like the Cowboys would be on their way to a rout, leading by as many as 15 points in the first half. But the pesky Wildcats battled back and closed to 38-34 with 10:16 remaining on Gilson DeJesus' follow shot.
However, the Cowboys re-established control, reeling off the next seven points.
Victor Williams hit a 12-footer from the right baseline, Sanders had a steal and dunk, Ivan McFarlin made a foul shot and Allen capped the spurt with another dunk, making it 45-34 with 7:53 remaining. Oklahoma State led by at least eight points the rest of the way.
"We started out hot and were satisfied where we were in the game," Allen said. "We had it in our mind that we were just going to blow them out. They made some shots and slowly chipped away at the lead."
The Cowboys, who lead the conference in defense, once again got it done on that end of the floor, forcing 19 turnovers and holding the Wildcats to 41 percent (23-of-58) shooting.
"I thought defensively we played a super game," Sutton said. "We made them turn the ball over 19 times and held them to 40 percent shooting. The only thing I would be critical on defense was that our interior players didn't play as well as they needed to play."
"The story of the game was turnovers," Kansas State coach Jim Wooldridge said. "When you go on the road and play a good team, you have to be precise with the ball and not turn it over in transition."
Trying to bounce back after the loss to Texas, the Cowboys scored the game's first eight points and were in front 21-6, on McFarlin's reverse layup with 10:09 left in the half.
But the Cowboys managed just six points the rest of the half, allowing the Wildcats to claw within 27-23 at the break.
