STILLWATER, Okla. (Interstat) — In a high-octane Big 12 shootout defined by offensive firepower and critical defensive stands, Oklahoma State outlasted BYU 99-92 on Wednesday night at Gallagher-Iba Arena.

The game, which saw both teams eclipse 90 points and shoot over 50% from the field, was ultimately decided by Oklahoma State’s ability to capitalize on BYU’s mistakes and execute in the final minutes. The Cowboys improved to 16-6 overall, while the Cougars fell to 16-5.

The contest was a tale of two halves that started as a mirror image. Both teams entered halftime knotted at 41, but the second half exploded into a scoring frenzy. Oklahoma State erupted for 58 points after the break, fueled by a more aggressive defensive approach that generated turnovers and transition opportunities. BYU, despite scoring 51 of its own in the second half, could not keep pace down the stretch.

The most important part of the game unfolded in the final five minutes. With Oklahoma State clinging to a narrow lead, the Cowboys forced a series of key stops and converted at the free-throw line to create separation. Anthony Roy, who finished with 30 points, was instrumental in the closing sequence, drawing fouls and hitting clutch free throws. His two free throws with 30 seconds left pushed the Oklahoma State lead to 97-92, effectively sealing the outcome after BYU had trimmed a deficit that was as large as nine points.

Roy’s performance was complemented by a balanced Cowboys attack. Jaylen Curry added 18 points, Vyctorius Miller provided a crucial spark off the bench with 14 points, and Parsa Fallah controlled the interior with 13 points and two blocks. Kanye Clary orchestrated the offense with nine assists.

BYU was led by a spectacular 36-point effort from AJ Dybantsa. The forward from Brockton, Massachusetts, was efficient and relentless, but received inconsistent support. Richie Saunders scored 20 points and Robert Wright added 15, but the Cougars’ offense was hampered by 16 turnovers, which Oklahoma State converted into 22 points off free throws alone. The Cowboys also dominated the assist battle, 10-5, and recorded 10 steals to BYU’s five.

Statistically, the game was an offensive showcase. Oklahoma State shot 54.7% from the field and posted an offensive rating of 125.1 on 79 possessions. BYU was nearly as efficient, shooting 50% with a 117.8 offensive rating. The difference came at the charity stripe, where Oklahoma State attempted 34 free throws, making 22, compared to BYU’s 17 attempts.

The result defied pregame projections that heavily favored BYU. The Cougars had been installed as a 5.5-point favorite, and statistical models gave them a 72% probability of victory. The combined score of 191 points sailed over the pregame over/under line of 170.5.

Oklahoma State’s victory marks a significant resume boost as it navigates the heart of the Big 12 schedule. The Cowboys travel to face Arizona on Saturday. BYU, which has now lost two of its last three games, must regroup quickly for a home showdown with Houston, also on Saturday.
