Utah State stuns No. 7 Tennessee in five-set NCAA tournament upset
Utah State walked into the NCAA tournament as one of the nation’s hottest teams but still largely unheralded. It walked out of Desert Financial Arena in Tempe, Arizona on Dec. 4 with something far more substantial: its biggest win in more than two decades.
Behind a masterful performance from setter Kaylie Kofe, a senior-star turn from Tierney Barlow and the poise of a young roster that refused to wobble when the moment tilted against them, the Aggies outlasted No. 7 overall seed Tennessee — 25-19, 25-15, 20-25, 18-25, 15-11 — to claim the program’s first NCAA tournament win since 2001.
“That’s an unbelievable Tennessee team,” head coach Rob Neilson said. “We gave them all they could handle in those first two sets, and then they responded. They’re a great team, obviously — well-coached and talented, physical. Then you get to a fifth set, and it’s a coin flip. I thought we made enough plays and battled and came through adversity. I’m really proud of this group, and I’m excited that we get to play some more volleyball together.”
Utah State has now won 22 straight matches, the third-longest active streak in Division I, and hasn’t lost since Sept. 18. But on Thursday night, it took everything — composure, creativity, resilience and a whole lot of firepower — to survive an avalanche of pressure from a Tennessee team that had rediscovered its identity after a shaky start.
“I turned to my team, and I was like, ‘We literally have nothing to lose,'” Kofe said. “‘There’s 15 points — 30 minutes of our time. Give everything you have, 110%.’ And that’s exactly what we did.”
Few expected Utah State to overwhelm Tennessee physically, but that’s exactly what happened, especially in the first two sets.
In the first set, the Aggies came out flying. Loryn Helgesen delivered early kills, Mara Stiglic tooled the block repeatedly and Kofe — all 5-foot-8-inches of her — rose for a solo stuff that sent USU’s bench into a frenzy. Tennessee’s hitters, ranked No. 11 nationally in efficiency, were stalled at .182 in the opening frame.
When the Aggies found themselves tied 19-19, they didn’t blink — they blasted off. A 6-0 closing run featured a Stiglic back-row dagger and consecutive Helgesen/Barlow blocks to seal a 25–19 win.
The second set was even more stunning: a 25-15 demolition where Utah State hit .444 and at one point held a 14-3 lead. Barlow and Stiglic shredded the Lady Vols’ block, Kendel Thompson dropped in an ace and Andrea Simovski, Helgesen, Lauren Larkin and Barlow all joined the offensive avalanche. Every Utah State attacker looked in rhythm and confident.
Tennessee, meanwhile, looked shaken: late on reads, out of system and searching for answers.
Then the match flipped.
Tennessee’s athletes and SEC battle scars emerged in the third and fourth sets, and the Lady Vols rediscovered the formula that made them a No. 7 seed: massive serve pressure and firepower from the pins.
Two straight aces from Starr Williams, another from Hayden Kubik and a cascade of USU serve-receive errors sent the Aggies scrambling. The Vols produced 8 aces across sets three and four, and USU suddenly struggled on first contact.
Williams took over the third set with 2 aces and a seven-point surge. Williams and Sydney Jones combined for 15 kills across the final two sets, and Tennessee’s block began taking away Utah State’s rhythm.
When the Lady Vols closed the fourth set 25-18 on their eighth ace, the arena felt like it had tilted sharply toward the favorites. Momentum, noise and pressure — all of it leaned orange.
But the Aggies didn’t flinch.
With Tennessee carrying all the energy into the fifth set, Utah State calmly reset, a theme of their whole season. A UT service error gave USU the first point, and then Simovski, the Mountain West tournament MVP, delivered the spark that changed everything.
Simovski hammered three kills in a row to stretch the lead to 6-3. With every point, Utah State’s sideline grew louder, and Tennessee’s block grew more uncertain.
“I think we all just have a common goal,” Kofe said. “We love winning, and we’re so competitive. That’s why I love this team. We all come out there ready to work, and I can count on all my teammates to do their job.”
Stiglic tooled the block to make it 7-4. Larkin and Stiglic roofed a Tennessee swing to push it to 9-5. And when Kofe delivered a reverse back set to Helgesen for a maybe the strongest swing of the night, even Tennessee’s bench seemed to exhale for the first time all night.
Still, the Lady Vols fought. Behind brilliant digging from libero Gulce Guctekin, Tennessee closed it to a 12-11 Aggies lead with back-to-back strikes from Jones.
But the Aggies responded again, with Stiglic and Helgesen securing a massive block and Barlow executing two consecutive slide plays to clinch the win.
Fittingly, it was their only senior — the one they call “the team mom” — who finished it.
“Tierney is so valuable not just on the court but as a person,” Kofe said. “We all love her. Her maturity means so much to us.”
Utah State out-hit Tennessee .312 to .228, recorded 9 blocks and despite the avalanche of pressure in the middle sets, found enough stability in the fifth to control the match’s final 15 points.
With the victory, Utah State secured its first NCAA tournament win since 2001, years before any player on the roster was born.
For Kofe, who started her career as a walk-on, the moment carried weight.
“I didn’t have the most traditional recruiting process, and coming in as a walk-on, it means a lot to be here,” she said. “This is a moment we’ve all dreamed of as little girls. And I’m getting to live it.”
It is also the most significant win yet in a season defined by a historic streak, incredible growth and a fearless competitive identity. The Aggies didn’t crumble when a top-SEC team punched them in the mouth — they punched back harder.
And now, after one of the biggest upsets of the tournament, they get to play again tomorrow, this time with national eyes firmly upon them.
Utah State will face No. 2 seed Arizona State — the No.8-ranked team in the nation — at 6 p.m. MT in Tempe. The Big 12 champion Sun Devils bring an explosive offense and have the advantage of playing on their home court.
It will be an uphill battle for the Aggies to pull off another upset tomorrow, but beating the odds is exactly what has carried them this far.
