Down three key players who are quarantined and road weary, No. 1 Stanford needed every defensive stop down the stretch.

Haley Jones returned to her hometown and had 18 points and six rebounds, and No. 1 Stanford beat No. 11 Oregon 70-63 on Friday at Kaiser Permanente Arena in Santa Cruz. The Cardinal were playing in Northern California for the first time in nearly a month.

Fran Belibi’s three-point play with 17 seconds remaining in the third quarter capped a second decisive 9-0 run that period by the Cardinal (10-0, 7-0 Pac-12), who played without guards Lexie Hull and Hannah Jump and forward Alyssa Jerome because of COVID-19 protocols and contact tracing.

“It just meant a lot to me and the team,” senior Anna Wilson said. “It’s amazing to be down three people — three important people, too, whether it’s a leader, a scorer, a 3-point shooter, rebounder — to not have those big pieces and understand that our team is playing for them and just how close our team is.”

Stanford played in Northern California for the first time since a win at Cal on Dec. 13, and the Cardinal haven’t been able to play or practice on campus since Santa Clara County’s restrictions on sports came down Nov. 28.

Stanford’s run spanning the final two quarters reached 13-0 before Sydney Parrish’s three-point play at 7:48 of the fourth. Parrish finished with 14 points.

Maddie Scherr swished a long 3 at the first-quarter buzzer for a 20-16 Oregon lead, and the Cardinal trailed at halftime for the first time all season, down 33-32.

The Ducks (8-2, 6-2) lost for just the second time in the past seven meetings in the series after beating the Cardinal three times in 2019-20 — including an 89-56 rout in the Pac-12 tournament title game.

“I’m disappointed, quite frankly,” Oregon coach Kelly Graves said. “I’m proud of the players for how we continued to battle. But I’m disappointed we lost the game. We’ve won this conference three times in a row. We expect to win.”

Jones, the Pac-12 rebounding leader, also had two of her team’s six steals. Senior point guard Kiana Williams struggled with her shot to finish 3-for-13 for 13 points, but converted 8 of 9 free throws.

Wilson added 11 points and nine rebounds for the Cardinal, who committed 17 turnovers.

“That was the thing I was most disappointed about,” Stanford coach Tara VanDerveer said. “We were too careless with the ball.”
