STILLWATER, Oklahoma (Ticker) -- Victor Williams' game-winning jumper for Oklahoma State made Oklahoma coach Kelvin Sampson hopping mad.
Williams made a controversial basket with 3.6 seconds left as No. 24 Oklahoma State extended its winning streak to 11 games with a 48-46 victory over fifth-ranked Oklahoma in a Big 12 Conference clash.
The contest was knotted, 46-46, when Williams, who led the Cowboys (13-1, 2-0 Big 12) with 16 points, appeared to release a mid-range jumper just after the shot clock reached zero.
After the senior's shot went in off the glass, Sampson jumped to the center of the court, swinging his arms like a referee waving off a basket.
Sampson was not assessed a technical foul, the officials allowed the basket and Oklahoma's Ebi Ere hit the side of the backboard from the left corner as time expired.
"You guys saw the game. Write what you think," Sampson said.
Ivan McFarlin contributed 11 points and 14 rebounds for Oklahoma State as the junior forward combined with Williams to score 23 of the Cowboys' 27 points in the second half.
Freshman Kevin Bookout paced Oklahoma with 14 points and 11 rebounds, but the Sooners (10-3, 1-1) had a four-game winning streak snapped.
The Cowboys recorded their second win over a top-10 opponent this season. Williams made six free throws down the stretch on November 30 as Oklahoma State held then-No. 10 Michigan State to one basket over the final 4 1/2 minutes and recorded a 64-61 victory in the Great Alaska Shootout.
In this one, Williams' layup with just under three minutes remaining put Oklahoma State back in front, 44-43.
In a defensive battle, the teams took turns missing shots until McFarlin's tip-in with 1:40 to play opened a three-point cushion for the Cowboys.
Oklahoma star Hollis Price struggled throughout, hitting just 2-of-14 from the floor and not getting to the foul line until there were 77 seconds remaining. A 92 percent free-throw shooter, Price made just 1-of-2 and pulled Oklahoma within 46-44.
The Sooners shot just 7-of-15 from the line (46 percent).
"Sometimes you make your breaks, sometimes you get some," Sampson said.
After Williams missed a pair of shots, Price sank a jumper with 40.4 seconds left to tie it, 46-46, and set up the thrilling finish.
Oklahoma fell to 8-11 against Oklahoma State under Sampson, including a 2-7 mark at Gallagher-Iba Arena.
