Aaryn Ellenberg scored a season-high 27 points and four other Sooners reached double-digit scoring as No. 13 Oklahoma's perimeter shooting paced its 100-61 victory over Oregon.
Ellenberg made seven of 12 3-pointers as part of 17-for-38 team shooting from beyond the arc. OU's 38 3-point field goal attempts were a school record.
It was the Sooners' second win in as many days at the Rainbow Wahine Showdown. OU defeated Arkansas 73-70 on Friday.
The Sooners started sluggish, beginning the game with three consecutive turnovers before head coach Sherri Coale substituted for all five players on the court with her five reserves. The backups kept Oregon scoreless until the starters returned and began a 29-4 scoring run.
Oklahoma led 55-35 at halftime.
Freshmen Nicole Kornet and Maddie Manning each had career bests with 15 and 11 points, respectively. Morgan Hook scored 12 points and Portia Durrett added 10.
Amanda Delgado led Oregon with 16 points.
It was the first ever meeting between the Sooners and Ducks.
