Chiney Ogwumike scored 23 of her 29 points in the second half and added 16 rebounds to help No. 6 Stanford beat Southern California 75-66 on Sunday night.
Joslyn Tinkle had 15 points while Sara James added 13 for the Cardinal (16-2, 5-1 in the Pac-12), who won their second straight since having a long conference streak end against California last Sunday. Amber Orrange added 11 points.
Cassie Harberts scored 21 points to lead the Trojans (7-10, 4-2 Pac-12), who lost their 11th straight to Stanford. Ariya Crook added 18 points.
Stanford opened a 19-point edge in the first four minutes of the second half and had to stave off a fierce Trojans rally.
Southern California's only senior and second leading rebounder, Christina Marinacci, missed her fourth straight game because of an injury sustained in the Trojans' victory over Oregon two weeks ago.
