STANFORD, Calif. -- Stanford can always depend on the Ogwumike sisters, and now some other players are chipping in.
Nnemkadi Ogwumike had 25 points and eight rebounds, and No. 4 Stanford beat UCLA 82-59 on Sunday.
Chiney Ogwumike added 19 points for the Cardinal (22-1, 13-0 Pac-12), who won their 19th straight since losing at Connecticut on Nov. 21. Toni Kokenis scored 12 points and Josyln Tinkle added 10 points and nine rebounds.
"We count every night on Nneka and Chiney," coach Tara VanDerveer said. "This was a big game for Jos and we had others score and getting assists. To get to where we want to go, we need other people contributing."
Chiney Ogwumike was limited to eight minutes in the first half because of foul trouble.
"I wouldn't necessarily say it changes the dynamics," Nneka Ogwumike said. "I think it helped other people step up. Tink had a great game. When we needed her on the perimeter, she stepped up, and when we needed her down low, she got in there. I think we did a good job of finding each other."
Markel Walker had 16 points and 10 rebounds for the Bruins (12-12, 7-6 Pac-12), who lost their second straight following a four-game winning streak. Thea Lemberger added 13 points.
Rebekah Gardner scored 15 and became the 26th UCLA player to surpass 1,000 points. She now has 1,006.
"I think our whole team loves the challenge," said Walker, who averages a double-double after missing the first seven games because of offseason thumb surgery. "Playing against the sisters is hard because they both rebound so well and they run the floor so well. They just don't stop; they keep working."
Stanford extended its school record home winning streak to 76 games and 70 against Pac-12 opponents, which includes tournament games.
The Cardinal need one more win or a California loss to clinch at least a share of their 12th consecutive conference title.
UCLA made the Cardinal work during a tight first half. Stanford never led by more than five and the Bruins held early advantages in rebounding and points in the paint.
But the Cardinal went on a 19-6 run -- with 13 points from the Ogwumike sisters -- that spanned both halves to open a 42-32 advantage with 16:23 remaining. UCLA never got closer than eight the rest of the way.
"We showed flashes," Bruins coach Cori Close said. "We have the ability to force Stanford into playing out of rhythm. We have to learn how to sustain that."
The Bruins missed their last nine shots of the first half over more than 6½ minutes but still led 26-23 with 5:21 left by hitting eight straight free throws.
