Oklahoma State tops No. 16 BYU 99-92 as Anthony Roy’s 30 outduels AJ Dybantsa

A high-scoring night in Stillwater reshapes the Big 12 middle tier

Oklahoma State defeated No. 16 BYU 99-92 on Wednesday, Feb. 4, 2026, at Gallagher-Iba Arena, earning the Cowboys’ highest-ranked win of the season and extending their recent uptick to a second straight victory. The result moved Oklahoma State to 16-6 overall and 4-5 in Big 12 play, while BYU fell to 17-5 and 5-4 and absorbed a third consecutive loss.

The game paired two performances that could stand among the Big 12’s most notable individual scoring outputs this season: Oklahoma State guard Anthony Roy produced a season-high 30 points, while BYU freshman AJ Dybantsa scored 36 with seven rebounds. Oklahoma State’s win prompted a postgame court-storming, underscoring both the magnitude of the upset and the stakes of Big 12 positioning as the schedule tightens.

How Oklahoma State built and protected its edge

Oklahoma State’s path to the upset was shaped early by disruptive defense and the ability to convert mistakes into points. The Cowboys forced 16 turnovers and turned them into 21 points, creating early separation as BYU struggled to settle offensively. Nine of those turnovers came in the first 11 minutes, during which Oklahoma State surged ahead 29-15.

BYU recovered from a scoreless opening stretch and erased the deficit by halftime, tying the game 41-41 after Dybantsa capped the first half with a driving dunk in the final seconds. The Cougars briefly took their first lead early in the second half, but Oklahoma State reasserted control in the closing minutes. A Roy three-pointer pushed the Cowboys ahead 81-69 with just over four minutes remaining, giving Oklahoma State enough cushion to withstand BYU’s final pushes.

• Oklahoma State leaders: Anthony Roy 30 points; Jaylen Curry 18; Vyctorius Miller 14; Parsa Fallah 13; Christian Coleman 10.
• Ball pressure impact: Kanye Clary recorded nine assists and five steals as Oklahoma State finished with 10 steals.
• BYU leaders: AJ Dybantsa 36 points on 13-of-20 shooting with five made 3-pointers; Richie Saunders 20 points and eight rebounds; Robert Wright III 15 points.

BYU’s star power, Oklahoma State’s margin details

Dybantsa’s efficiency and shot-making kept BYU within reach throughout, including a second-half stretch in which the Cougars narrowed the deficit and momentarily held the lead. But BYU’s turnover total and Oklahoma State’s late-game shot-making proved decisive in a game where both teams reached the 90s.

The loss also marked BYU’s first defeat to an unranked opponent this season and ended the Cougars’ streak of 22 consecutive wins over unranked teams. For Oklahoma State, the performance represented a sharp contrast to its previous home game against a ranked opponent, an 84-71 loss to No. 9 Iowa State in which the Cowboys trailed by 30 at halftime.

With both teams scoring at a fast pace, Oklahoma State’s ability to create extra possessions and cash in on turnovers functioned as the separating factor late.

What comes next

Both teams now face immediate tests against top-10 competition on Saturday: BYU is set to host No. 8 Houston, while Oklahoma State is scheduled to visit No. 1 Arizona.
