LOS ANGELES (AP) - Chiney Ogwumike had 26 points and 15 rebounds for her record-setting 20th double-double of the season and No. 4 Stanford defeated Southern California for the 12th straight time, 79-55 on Friday night.
Joslyn Tinkle added 17 points and 11 rebounds, Mikaela Ruef had a career-best 12 points and eight rebounds, and Amber Orrange had 10 points to help keep the Cardinal (23-2, 12-1 Pac-12) tied with No. 6 California atop the league standings.
Stanford earned its ninth straight victory and improved to 14-0 away from home this season.
Alexyz Vaioletama scored 14 points and Cassie Harberts added 13 for the Trojans (8-16, 5-8), who have dropped five in a row and eight of nine.
Ogwumike's double-double bettered the single-season record that she and older sister Nneka set last season before Nneka graduated and began playing for the WNBA's Los Angeles Sparks. Chiney has 50 double-doubles in her three-year career, one shy of Nneka's record of 51 set from 2008-12.
