AUSTIN, Texas (Ticker) -- Brandon Mouton savored the moment, but not for long.
Mouton scored 17 points and 10th-ranked Texas withstood a pair of 3-point attempts in the final seconds to escape with another close win over No. 25 Texas Tech, 74-71.
The Longhorns (21-4, 12-2 Big 12) scored their final five points from the free-throw line to win for the ninth time in 10 games, but they again had trouble with the pesky Red Raiders.
Mouton, a senior playing in his final home game, gave the Longhorns a three-point lead by hitting two free throws with 14 seconds left.
"It was an emotional and sad day, but great for our seniors to get this win," Mouton said. "It hasn't really dawned on me that this was my last game on this court. We have to embrace this win, enjoy it, and move on."
The Red Raiders (19-9, 7-7) had a chance to tie, but Andre Emmett missed a pair of 3-pointers in the final four seconds. He appeared to be bumped on his first attempt, but no foul was called. Emmett chased down the rebound and was able to launch another failed long-range attempt at the buzzer.
With Oklahoma State next on the schedule, there is little time to celebrate. The Longhorns and Cowboys are tied for the Big 12 lead.
"We have two games left and a chance to have a great end to the regular season," Texas coach Rick Barnes said. "The guys know that on any given night, if we don't play, we can get beat."
Emmett scored 21 points, but did not prevent the Red Raiders' seventh loss in 10 games. The recent struggles began with an overtime loss to the Longhorns on January 26.
"Texas did a great job of maneuvering their players, creating tough matchups and playing hard," Texas Tech coach Bob Knight said.
Texas improved to 16-2 all time against Texas Tech since the formation of the Big 12 Conference, including a 12-1 mark under Barnes.
Freshman P.J. Tucker added 15 points and 10 rebounds while Royal Ivey, Kenny Taylor and Jason Klotz each scored 11 for Texas. Klotz came off the bench and frustrated the Red Raiders while grabbing six rebounds.
"If I could have any player in the league, it would be Jason Klotz," Knight said. "He's hard to play against, he makes huge baskets and he's tough."
Texas built a 10-point lead on several occasions in the second half, the first coming on a 3-pointer by Mouton with 11:08 left that made it 54-44. But the Red Raiders made a series of comebacks, and reduced the lead to 63-60 on a 3-pointer by Darryl Dora with 4:40 left.
Texas Tech led by as many as six points in a tight first half, taking a 21-15 advantage on a jumper by Mikey Marshall with 6:05 left.
Freshman Jarrius Jackson scored 15 points and Ronald Ross and Robert Tomaszek each had 11 for the Red Raiders.
