Bryce Williams' steal in the final seconds of overtime sealed Oklahoma State's 82-77 victory over No. 13 Texas Tech on Saturday in yet another tight contest between the teams.

It was the third time in as many Big 12 Conference games between the Cowboys and Red Raiders decided by a single possession or in overtime.

Avery Anderson and Isaac Likekele led Oklahoma State (7-2, 1-2 Big 12) with 17 points apiece. Mac McClung notched 21 points for Texas Tech (8-3, 1-2) before fouling out in overtime.

Texas Tech's Kevin McCullar buried a 3-pointer to pull the Red Raiders within 80-77 with 49 seconds on the clock in the extra period and got the ball back with 20 seconds left on a Kyler Edwards rebound.

Texas Tech called a timeout with 11 seconds to go, but Williams swiped the ball and fed Anderson for an Oklahoma State layup right before the final buzzer sounded.

Williams' steal and fast-break slam dunk had given Oklahoma State some breathing room with 1:54 to go in overtime.

An exchange of clutch free throws by both teams punctuated the last few minutes of regulation. Oklahoma State's Cade Cunningham drained three free throws after he was fouled while shooting from 3-point range to tie the score 68-all with 27 seconds remaining in the second half.

On the Red Raiders' ensuing possession, Edwards was whistled for an offensive foul with four seconds to go, but the Cowboys weren't able to hit a late shot.

Trailing 45-34 with just over 16 minutes remaining, Texas Tech methodically ate into the deficit, tying the score at 49-all with 8:58 to go. The Red Raiders grabbed a 55-53 lead on Terrence Shannon's layup with 6:47 remaining.

From there, the teams traded the lead six times down the stretch with neither team able to create a two-possession cushion.

The Cowboys charged out of the gate in the first half to take a 22-10 lead with eight minutes gone. Texas Tech clawed back despite a miserable first half on the offensive end.

The Red Raiders shot just 27.6 percent from the floor (8 of 29) in the first 20 minutes and couldn't generate any momentum on defense. Oklahoma State was 5 of 12 from 3-point range in the first half to take a 37-28 lead into the break.
