Jan. 27 (UPI) -- Senior guard Austin Reaves scored a game-high 23 points to lead the Oklahoma Sooners to a one-point upset victory over the Texas Longhorns.
Reaves also had six rebounds in the 80-79 victory on Tuesday at the Frank C. Erwin Jr. Center in Austin, Texas. The Longhorns entered the game ranked No. 5 in the coaches poll, while the Sooners were unranked.
"It's major. We have to keep it going," Reaves told reporters. "We can't get too confident, but have the confidence that we can beat anybody in the country."
The Sooners trailed 14-6 about 7:31 into Tuesday's game before they went on a 13-0 run and never looked back.
Oklahoma used the run to take a 19-14 lead and didn't trail for the rest of the game. Reaves scored 12 points in the first half and the Sooners led 43-34 at the break.
The Longhorns cut into the Sooners lead several times down the stretch, but Oklahoma managed to hang on. The Sooners led 78-70 with 3:50 remaining before the Longhorns went on a 7-0 run to cut the lead to one point.
Reaves then made two free throws to push the Sooners lead back to three points. Andrew Jones made two free throws for the Longhorns with five seconds remaining for the final points of the night.
