Colorado Stuns No. 14 BYU in Big 12 Volleyball Opener
A Landmark Victory in Provo
The Colorado Buffaloes delivered one of their biggest wins in recent memory, toppling No. 14 BYU in four sets — 25-14, 25-23, 23-25, 25-21 — Thursday night at the Smith Fieldhouse in Provo. The Buffs not only handed BYU its first loss of the season but also opened Big 12 play with a dramatic statement. In front of more than 2,800 fans, Colorado improved to 10-2 overall and 1-0 in league play, while BYU dropped to 12-1 and 0-1 in the conference. It was Colorado’s first victory over a top-15 opponent since 2021, underscoring the team’s steady rise under head coach Jesse Mahoney.
Burilovic Leads the Charge
Junior outside hitter Ana Burilovic put together a standout performance that shaped the outcome from start to finish. She finished with 22 kills on efficient .333 hitting, added seven digs, and registered four aces that kept BYU’s defense on edge throughout the night. Burilovic’s consistency and ability to deliver in clutch moments gave Colorado the confidence to push through BYU’s rallies. Afterward, Mahoney praised his team’s preparation, noting that the group responded to two consecutive losses with one of its most complete matches of the year.
Early Dominance
Colorado wasted no time setting the tone. A 5-1 start forced BYU to burn an early timeout, and the Buffs never looked back. They closed the first set with a blistering .565 hitting percentage while holding the Cougars to zero. Sydney Jordan capped the frame with a decisive kill that sealed a commanding 25-14 win.
The second set featured more back-and-forth play. BYU surged ahead briefly at 14-13, riding the efforts of Brielle Kemavor and freshman sensation Suli Davis. Yet Colorado countered with a composed response, stringing together timely kills from Burilovic and Lily Dwinell. Even as BYU mounted a late rally to tie the score, the Buffs steadied themselves in the final points, taking the set 25-23 and grabbing full control of the match.
BYU Extends the Battle
The Cougars showed their resilience in the third set. Setter Alex Bower guided the offense with sharp distribution, piling up assists as BYU built a 19-12 advantage. Claire Little Chambers and Davis took turns at the net, pushing the hosts closer to extending the contest. Colorado stormed back with an 11-3 run that stunned the home crowd, even tying the score at 22 after a Burilovic ace. But Bower reconnected with Chambers and Kemavor in the final rallies, allowing BYU to escape with a 25-23 win and keep the match alive.
The Final Push
The fourth set reflected the intensity of the entire evening. Both teams traded points to an 8-8 deadlock, neither side able to create separation. Then Colorado’s depth began to shine. Kills from Dwinell and middle blocker Cayla Payne, paired with an ace from freshman Inés Losada, forced BYU into another timeout. The Cougars responded with a short burst to briefly tie the score, but the Buffs answered immediately with their own run. Burilovic’s serving pressure and Payne’s blocking presence helped Colorado establish a late cushion. At match point, fittingly, another ace dropped in to secure the 25-21 clincher and seal the upset.
Complete Team Effort
Although Burilovic’s star performance stood out, Colorado’s success stemmed from contributions across the lineup. Payne added nine kills while leading all players with five blocks. Setter Rian Finley orchestrated the offense with 47 assists, while also contributing nine digs. Dwinell chipped in 10 kills and four blocks, and libero Sarah Morton steadied the defense with nine digs and a pair of service aces. Collectively, Colorado outplayed BYU statistically in nearly every category, finishing with more kills, assists, blocks, and aces.
BYU’s Response
For BYU, Davis led the way with 15 kills and nine digs, though she hit just .103 against a disciplined Colorado block. Kemavor recorded 13 kills and four blocks, while Chambers added 11 kills and steady back-row defense. Bower’s double-double of 37 assists and 10 digs was another highlight, yet the Cougars’ 28 attack errors proved too costly against an opponent firing on all cylinders. Head coach Heather Olmstead admitted her team was out of rhythm, noting that the Cougars appeared flat in multiple phases of the game. With Iowa State visiting Provo next, she stressed the need for a quick turnaround.
Looking Ahead
The Buffaloes left Provo with both momentum and validation. By beating a nationally ranked opponent on the road, Colorado announced its intent to compete at the top of the Big 12. The win came just a week after consecutive losses to in-state rival Colorado State, demonstrating the team’s ability to reset and rise to the occasion against an elite opponent. For BYU, the defeat was a reminder that in a league as competitive as the Big 12, there are no easy nights. The Cougars will look to regroup as they continue their first full season in the conference.
Colorado’s upset highlighted the program’s growth and resilience, while BYU’s response will show how quickly a top-15 team can bounce back. For fans, it was a thrilling showcase of the depth and competitiveness that defines Big 12 volleyball.
