PORTLAND, Ore. — Matas Vokietaitis had 23 points and a career-high 16 rebounds, Tramon Mark added 19 points and four clinching free throws, and 11th-seeded Texas won its second NCAA Tournament game in three days with a 79-71 victory over No. 6 BYU in the West Region on Thursday.

Dailyn Swain had 14 points and Jordan Pope had 11 for Longhorns (20-14), who overcame a 35-point, 10-rebound performance by Cougars freshman AJ Dybantsa in what might have been his final college game.

Dybantsa, a projected No. 1 overall pick in the 2026 NBA Draft if he leaves school by some, was 11 of 25 from the field and made all 12 of his free-throw attempts.

Texas took a 68-51 lead with 11 minutes remaining when Dybantsa was called for goaltending on Mark’s layup. Then Dybantsa took over.

He had started a run of 15 straight points for BYU (23-12) with a dunk at the 13-minute mark. Dybantsa scored all of the Cougars’ points in a 13-2 run when they closed to 70-64 with 4:08 left.

Vokietaitis followed his own miss for a 72-64 lead before Robert Wright III’s layup closed it to 72-68 with 2:07 left. Pope’s 3-pointer pushed the Longhorns’ lead to seven with 1:29 left.

Aleksej Kostic’s 3-pointer brought BYU within 75-71 with 1:17 remaining, and the Longhorns could not build a cushion when the Cougars were forced to foul.

Vokietaitis missed all seven of his free-throw attempts in the second half, including the front end of three one-and-ones in the final 3 1/2 minutes. His two misses with 31 seconds remaining kept it at 75-71.

But Vokietaitis blocked Wright’s drive with 23 seconds left, and Texas closed out with four Mark free throws.

“Matas played potentially the best game he’s played at Texas,” Texas coach Sean Miller said. “The big reason we won is because of what he did.”

The Cougars had no early answer for 7-foot Vokietaitis, who had 15 points and 11 rebounds at the half, including seven offensive rebounds. He finished with nine offensive boards.

“I love to play physical. That’s what they like to do,” Vokietaitis said. “Talking about free throws, I don’t know what to say. I need to work more on that. I’m usually making free throws.”

The Longhorns had a 40-31 rebounding edge for the game. They were plus-12 on the boards in the 60-66 victory over North Carolina State in Dayton on Tuesday in the First Four.

They did not land in Portland until about 6 a.m. local time Wednesday.
