Markel Brown hit a 3-pointer with 12 seconds to lift No. 11 Oklahoma State to a 73-72 win over West Virginia on Saturday.
The Cowboys (14-2, 2-1 Big 12) trailed for most of the game, but got solid efforts from their top two scorers in the final minutes.
Marcus Smart had 22 points and 13 rebounds. Le'Bryan Nash added 18 points and Brown finished with 12.
Terry Henderson scored a season-high 21 points for West Virginia (10-6, 2-1), which saw its three-game winning streak snapped. Juwan Staten added 20 points and Devin Williams had 12 points and 13 rebounds.
West Virginia's Eron Harris, Smart, Brown and Staten represented four of the top six scorers in the conference. Harris finished with 11 points, more than seven below his average.
Henderson's 3-pointer put the Mountaineers ahead 72-70 with 1:14 remaining.
Freshman Nathan Adrian, who's been mired in a shooting slump, sent the home crowd into a frenzy with a block of Nash's shot attempt with 1:04 to go and West Virginia got the ball back on the tie-up.
But Staten missed a layup with 27 seconds left and Smart sent a pass to Brown, who made the go-ahead shot from the top left side of the circle.
Staten missed another layup in traffic in the closing seconds.
Oklahoma State gave up a season high for points in the first half for the third straight game, but took advantage of a pair of West Virginia turnovers and went on an 8-2 run to open the second half for its first lead 47-43 with 16:22 left.
Smart went to the bench with his third foul with 12:04 left, and the Cowboys did just fine without him.
Oklahoma State went on a 7-0 run, with Brown stealing a pass from Brandon Watkins and dunking the ball uncontested for a 57-52 lead with 10:24 left.
Smart returned from the sideline after three minutes and kept the Cowboys' momentum going with a pair of free throws and a 3-pointer.
West Virginia attempted just two free throws during its first-half run, but started getting free throws midway through the second half. The Mountaineers needed them because they made just one field goal over a 10-minute stretch after halftime.
Henderson broke the drought with a 3-pointer and Staten made a layup 32 seconds later to tie the score at 67-67 with 4:21 left. Each team made two field goals the rest of the game in a physical finish.
West Virginia set the tempo from the onset, leading by as many as eight in the first half before Oklahoma State got its act together with a 15-4 run to tie it. Devin Williams' turnaround jumper with 2 seconds left put West Virginia ahead 41-39 at halftime.
