Chiney Ogwumike scored a career-high 32 points in No. 4 Stanford's 65-45 win over Oregon State.
Ogwumike added 18 rebounds for the Cardinal (20-2, 9-1 Pac-12), who have won six straight games.
Jamie Weisner netted 13 points to lead the Beavers (9-13, 3-7).
Stanford led by as many as 16 in the first half before taking a 35-24 cushion into the break.
Oregon State's Ali Gibson opened the second stanza with a layup, but Ogwumike tallied six consecutive points to help the Cardinal regain control and they were never seriously challenged again.
