AUSTIN, Texas (Ticker) -- Due to a series of bad grades, Texas' season may now rest in the hands of the dynamic Daniel Gibson. The freshman seems to have no problem with that.
Gibson made all six of his 3-pointers and scored 20 points as No. 13 Texas posted an 80-73 victory over Texas Tech in Big 12 Conference play.
A starter opening the season, Gibson's role has been increased due to the loss of P.J. Tucker for academic reasons and LaMarcus Aldridge to a hip injury. He has responded with a series of stellar games, perhaps none bigger than this one.
"(Gibson) is playing smart," Longhorns coach Rick Barnes said. "He is getting a feel for what he needs to do. He is confident now. He has gotten smarter and the experience is helping him figure everything out."
Gibson matched the school's best all-time showing from behind the arc with his 6-of-6 effort and constantly provided a damaging 3-pointer to keep the Longhorns (15-4, 4-2 Big 12) in control.
After the Red Raiders got to within 45-39 six minutes into the second half, Gibson made his fourth 3-pointer to push the lead back to nine. When Texas Tech cut its deficit to 69-63 with five minutes left, Gibson capped his long-range effort to again give his team a nine-point advantage.
"I was happy to get such good shots," Gibson said. "The crowd really got into it and we were having fun. The ball just felt good leaving my hand."
Gibson, who had four of his team's six steals, is averaging 21.7 points over his last three games and has led Texas in scoring in four straight.
Due to the injuries and suspensions, the Longhorns played with just eight scholarship players but showed few effects.
"Fatigue was not an issue," Gibson said. "We have guys on our team that can play every position and sometimes they have to do that. Each player just goes out there and plays as hard as he can."
Kenton Paulino added 16 points and was 3-of-4 from the arc, part of the Longhorns' 14-of-21 3-point shooting.
Their signature run came midway through the second when they made four straight 3-pointers as part of a 16-11 run.
"I like their team, the way they play and the way they are coached," said Red Raiders coach Bob Knight, who fell to 1-7 vs. the Longhorns. "Texas is a good 3-point shooting team. I knew that about them before. It is really hard to beat a team that makes 14 3's."
Brad Buckman scored eight points and grabbed a career-high 14 rebounds for Texas, which improved to 13-1 vs. Texas Tech under coach Rick Barnes.
Ronald Ross scored 29 points and Devonne Giles added 18 and 15 rebounds but the Red Raiders (11-5, 3-2) could not overcome a first half in which they shot just 25 percent (10-of-40) and fell behind, 32-25.
"We knew we had to come out here and play 40 minutes of basketball," said Ross, who did his best to match Texas with six 3-pointers. "Our mistakes caught up with us at the end and we could not catch up. They are a good shooting team and it showed in the score."
