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.
Sharene 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.
