LOS ANGELES (AP) -- Atonye Nyingifa had career highs of 28 points and 16 rebounds, Nirra Fields added a career-best 17 points and UCLA outrebounded No. 10 Oklahoma on its way to an 82-76 upset Sunday.
The Bruins (2-2) beat a ranked opponent for the first time this season after earlier losses to Nebraska and North Carolina.
They got rebounds from seven of their eight players in dominating the boards, 49-29, including a 20-5 edge on the offensive glass. Fields had nine rebounds and Luiana Livulo had eight before fouling out.
Nicole Griffin scored 19 points for the Sooners (4-2), who ended UCLA's postseason hopes last spring with an 85-72 victory in the NCAA tournament.
Sharane Campbell added 13 points and Kaylon Williams 12 before both fouled out. The Sooners were in foul trouble much of the second half. The final margin represented the largest lead by either team in the half.
Griffin scored inside to draw the Sooners to 77-76 with 1 minute left. Morgan Hook missed a game-tying layup with 17 seconds to go and Aaryn Ellenberg, who scored 11 points on 2 of 13 shooting, also missed in the closing seconds.
That's when the Bruins preserved the upset at the line, where they finished 23 of 36.
Madeline Brooks, a seldom-used junior inserted because of foul trouble, got fouled and made both free throws, and Fields made a pair to close out the win.
The Sooners controlled the early part of the game, shooting 61 percent on their way to taking a 30-16 lead that included three consecutive 3-pointers.
The Bruins turned things around over the final 9 1/2 minutes of the half, outscoring Oklahoma 27-13 to go into halftime tied 43-all. Nyingifa scored 14 points, highlighted by grabbing her own offensive rebound and laying it in. Two possessions earlier, Lauren Holiday stole the ball and fed Thea Lemberger, who missed, before Holiday cleaned it up to complete a spurt of eight straight points.
Holiday, who had never attempted a 3-pointer in her two-year career, made two in the first half. She broke her nose with 8:25 left in the game.
