STANFORD, Calif. (AP) - Chiney Ogwumike scored three of her career-high 27 points in overtime and added a career-high 18 rebounds to help No. 4 Stanford wrap up a perfect first half of the Pac-12 season with a 74-71 victory over rival California on Saturday.
Toni Kokenis added 16 points, including two key free throws in overtime, and Nnemkadi Ogwumike had 12 to move past Val Whiting into fourth place on the all-time scoring list for the Cardinal (18-1, 9-0). Stanford has won 15 straight games overall and has a three-game lead over the Golden Bears (15-6, 6-3) and Arizona State at the midpoint of the conference season.
This one wasn't easy as the Cardinal allowed the final nine points of regulation to force overtime and then got only one basket in the extra session, a layup by Chiney Ogwumike on their opening possession.
Cal missed eight of its nine field goal attempts in overtime, including two 3-pointers by Layshia Clarendon that could have tied it on the final possession.
Brittany Boyd scored 19 and Clarendon added 17 for the Bears, who had won six straight games before losing their first matchup with rival Stanford under first-year coach Lindsay Gottlieb. Cal fell to 1-4 this season against ranked opponents, with the only win coming in Hawaii in November against former coach Joanne Boyle's Virginia team. The losses have been by a combined nine points.
Clarendon became the 22nd Cal player to reach the 1,000 milestone, finishing the day with 1,016.
Stanford extended its home winning streak to 74 games and has won 66 in a row against Pac-12 opponents. Cal was the last team to snap either of those streaks, beating the Cardinal 72-57 at Maples Pavilion on Feb. 4, 2007, and 57-54 in Berkeley on Jan. 18, 2009. Those are two rare wins for the Bears in this series as they have lost 39 of the past 42 meetings.
The Bears fought back repeatedly in this game. They scored nine straight to cut the deficit to five points. But Chiney Ogwumike blocked Reshando Gray at one end and Bonnie Samuelson hit two 3-pointers for Stanford to extend the lead to nine points.
Cal then forced overtime by scoring the final nine points of regulation. Clarendon's 3-pointer with 36.5 seconds left cut Stanford's lead to 69-67. After Taylor Greenfield missed a front-end of a one-on-one for Stanford, Clarendon hit two free throws to tie it with 27.6 seconds remaining.
Stanford had two chances to win it at the end of regulation by Nnemkadi Ogwumike missed a jumper and Kokenis' tip attempt rolled off the rim at the buzzer, sending the Cardinal to overtime at home for the first time since beating Tennessee 73-69 on Dec. 22, 2007.
Both teams struggled shooting in the first half, combining to make just one 3-pointer -- am early shot by Boyd -- in 16 long-range attempts. But Boyd helped Cal stay close for most of the half with 14 points before the break, nearly equaling the season-high of 15 she had last month at Saint Mary's.
The Bears got only one basket from someone other than Boyd in the final 9:30 of the half and trailed 38-29 at the break after late baskets by Nnemkadi and Chiney Ogwumike.
Former Stanford football coach Jim Harbaugh got a loud ovation when introduced to the crowd at halftime. Harbaugh is fresh off leading the San Francisco 49ers to a trip to the NFC title game, which ended last Sunday with a 20-17 overtime loss to the New York Giants.
