STANFORD, Calif. -- Only a few years ago, Joslyn Tinkle played a limited role behind former Stanford stars Jayne Appel and Nnemkadi Ogwumike. Even Tinkle couldn't have envisioned becoming a Stanford regular who is counted on each night on both ends of the floor.

Or becoming a 1,000-point scorer.

Tinkle reached the milestone early in the second half, and Chiney Ogwumike had 19 points and 12 rebounds for No. 4 Stanford in a 90-53 victory over Oregon State on Friday night for its 11th straight victory.

"Coming into this year, I knew it was my time," Tinkle said. "Regardless of any situations, if my shot wasn't falling, it's a big accomplishment. It's a cool thing to accomplish, especially at Stanford. Each game I go in knowing they rely on me. To be successful and go where we want to go, I have to bring it every game."

Amber Orrange added 15 points on 7-for-9 shooting, six assists and two steals for Stanford (25-2, 14-1 Pac-12), which has won 27 straight games against Oregon State and owns a 27-game home winning streak against the Beavers at Maples Pavilion.

Tinkle struggled with her shot but hit two late 3-pointers to finish with 11 points as Stanford stayed unbeaten in its past 11 games since a 67-55 loss to rival California at home Jan. 13. The sixth-ranked Golden Bears beat Oregon 77-55 in Berkeley, so Stanford kept pace atop the conference standings.

"This was a really special game for us," Ogwumike said. "We've been waiting for a time when everybody steps up at the right time. Today was a great starting point, playing hard for 40 minutes."

Ogwumike, coming off a 26-point performance in a 68-57 win at UCLA on Sunday, also had four blocked shots and two steals. Her highlight came on an acrobatic swish in which she released the ball from beneath the backboard while falling out of bounds into a cameraman after being fouled. The three-point play put the Cardinal ahead 65-35 with 11:26 remaining -- although Ogwumike didn't initially know she had scored until seeing her teammates cheer and raise their arms.

"I had no clue," she said.

On that play, Ogwumike also set a career high with 11 made free throws as Stanford shot 16-for-18 from the line. Sophomore Taylor Greenfield matched her career high with 18 points for Stanford, which shot 48.5 percent from the field.

"They have a superstar inside. We did a decent job slowing her down," Oregon State coach Scott Rueck said. "I thought we got decent looks, to be honest; we just didn't make them. The second half turned into a shooting drill. ... I think you learn from every loss. I liked our intensity, liked the way we executed."

Beavers leading scorer Jamie Weisner scored 12 points to lead cold-shooting Oregon State (9-18, 3-12), which went 22-of-68 from the floor for 32.4 percent in losing its ninth straight game.

"I thought they played really good defense on me," she said. "I just didn't get the ball in my hands much."

After Oregon State pulled within 12-11 in the first half, Stanford used a 16-4 run to pull away.

The Beavers shot 2-for-10 from 3-point range in the first half, missing six of their first seven. But they crashed the boards for 11 first-half offensive rebounds and held a 22-21 edge in the opening 20 minutes. The Cardinal wound up with a 46-34 rebounding advantage.

"I really think that if our team is serious, we will have to box out," Stanford coach Tara VanDerveer said. "We already lost one game because we didn't rebound. Our team is going to have to decide."

Stanford, which already has secured a first-round bye for the conference tournament in Seattle, leads the all-time series 51-6. The Cardinal wrap up their regular-season home schedule Sunday afternoon against Oregon before hosting the first and second rounds of the NCAA tournament in Maples next month.

Cardinal guard Toni Kokenis didn't dress and missed her fifth straight game with an undisclosed medical condition that has limited her all season. She last played Feb. 3 at Oregon State.

VanDerveer isn't sure whether Kokenis will return this season.

"I don't know. It's day to day. We're very hopeful," she said. "For us to not have Toni and have different people step up, this is really big. I'm really proud of how our team played tonight. This is a group, they're hungry, they want to play. I think we're finding ourselves at the right time."
