Stillwater, Okla. Tony Crocker scored a career-high 25 points, and Oklahoma snapped Oklahoma State's five-game winning streak in a Bedlam rivalry game loaded with NCAA Tournament implications for both teams.
With leading scorer Blake Griffin out following right knee surgery, Crocker picked up the slack by scoring 14 points in the first half.
Byron Eaton, who averaged 20.6 points during the win streak to direct the Cowboys (16-13, 7-8 Big 12) back into postseason contention, hit two free throws to cut the deficit to nine with 5:41 left, but OSU could get no closer.
Longar Longar scored 10 of his 12 points in the first half as the Sooners spoiled senior-night festivities for Marcus Dove and Tyler Hatch and most likely the Cowboys' NCAA Tournament hopes, too.
No Big 12 team ever has made the NCAAs with eight conference losses.
Missouri 81, Iowa State 75 (2OT)
