STANFORD, Calif. – Bonnie Samuelson knocked down five 3-pointers on the way to 17 points all scored in the first half, and No. 6 Stanford beat Arizona 74-48 on Sunday to move closer to a 14th straight conference regular-season crown.

Chiney Ogwumike scored 11 of her 15 points during a decisive run late in the first half that put the game away for the Cardinal (24-2, 12-2 Pac-12), who clinched a bye into the quarterfinals of next month's conference tournament in Seattle. They earned their 24th consecutive victory against the short-handed Wildcats.

Amber Orrange dished out nine assists to go with nine points and five rebounds in 24 minutes as coach Tara VanDerveer was able to rest her regulars for another long stretch given the lopsided result.

LaBrittney Jones scored 11 points for Arizona (5-20, 1-13).
