SANTA CRUZ, Calif. (AP) -- No. 5 Stanford lost its second straight game, failing to complete a late comeback against No. 6 UCLA, 70-66, Friday night at Kaiser Permanente Arena.
Charisma Osborne had 24 points, eight rebounds and three steals for the Bruins.
Michaela Onyenwere added 16 points and 10 rebounds for the Bruins (9-2, 7-2 Pac-12), Natalie Chou had 12, and Emily Bessoir 11.
Stanford (11-2, 8-2), then ranked No. 1, lost 77-72 in overtime at Colorado on Sunday.
"I wanted to come out in this game and really just play freely and just play how I play," Osborne said. "Credit to my teammates for giving me a pep talk before the game when we were getting ready and just telling me that no one can guard me and giving me a lot of confidence."
Added UCLA head coach Cori Close: "I just hugged her so tight after the game and just was like, 'Look, you did it. You lived it. You earned the confidence now of what it means to be an elite player in big games on both sides of the ball, on the road. I can't give you that confidence — you've got to earn it — but you sure earned a whole lot of confidence tonight.'"
Kiana Williams led the Cardinal with 19 points and five assists. Francesca Belibi had 14 points, Haley Jones added 12 points and five rebounds, and Lexie Hull had 11 points and six rebounds.
UCLA lost an 11-point lead in the second half, with Stanford rallying to tie at 66 with 1:47 remaining. Osborne hit two free throws with 1:23 remaining to put the Bruins back in front for good.
The Cardinal had a chance to tie or win in the final seconds, but Belibi committed the team's 14th turnover with 13 seconds left and UCLA put the game away at the free throw line.
"Everyone on our team knows it's not about 'me,' it's about 'us,' Close praised. "I just thought there was so much selflessness on display tonight. That was the difference in the game — our toughness, togetherness, and our selflessness to be able to play whatever role is needed."
Up next, Stanford returns to Santa Cruz on Sunday to host USC at 4 p.m. PT on the Pac-12 Networks.
