LOS ANGELES (AP) -- Three days after beating the top team in the nation, Texas couldn't protect a 17-point lead against a nonconference opponent.
The No. 4 Longhorns continued their early-season pattern of following a win with a loss, squandering a large first-half lead and losing 63-60 to UCLA on Sunday.
Noelle Quinn scored the go-ahead basket with 16.7 seconds remaining and finished with 27 points, helping the Bruins rally from an early 17-point deficit to knock off the Longhorns, who had just beat No. 1 Tennessee 74-59 on Thursday.
Nikki Blue added 13 points for UCLA (3-1) in the Bruins' first win over a top 10 team since Nov. 20, 1999, a 69-65 victory over then-No. 8 North Carolina.
"In my opinion, we lost it in the first half," said Texas coach Jody Conradt, whose team opened the season with a victory over No. 21 Penn State and then lost at No. 5 Georgia last Sunday. "We allowed UCLA to make some shots, to get confident, to get momentum."
Texas (2-2) was led by Tiffany Jackson's 19 points and career-best 15 rebounds. Jamie Carey added 15 points, and Annissa Hastings had 11 before fouling out with 2:05 left.
The Longhorns took a 60-59 lead with 33.1 seconds on a driving layup by Carey. After Quinn scored to put UCLA ahead, Texas' Nina Norman missed two free throws with six seconds left.
Quinn grabbed the rebound and was fouled. She made two free throws to give UCLA a 63-60 lead with 4.7 seconds remaining. Texas' Heather Schreiber missed a 3-point try from the corner as time expired.
UCLA missed 15 of its first 16 shots and trailed 33-25 at halftime. The Bruins closed within 41-39 on a 3-point by Blue with 11:16 left and tied the score at 43 when freshman Lindsey Pluimer scored to cap a 9-2 run.
"We were kind of rushing our shots early because they played such aggressive defense," UCLA coach Kathy Olivier said. "We talked before the game that it would be a game of runs."
