Kristian Doolittle scored 20 points to help Oklahoma defeat Iowa State 90-61.

Brady Manek scored 18 points and Alondes Williams added 14 for the Sooners, who outscored the Cyclones 50-25 in the second half.

Oklahoma followed up Saturday’s victory over No. 13 West Virginia by avenging its loss at Iowa State a month earlier and falling a point short of its season’-high point total.

Iowa State announced this week that guard Tyrese Haliburton will miss the rest of the season after fracturing his left wrist. The Cyclones shot just 34.5% in the second half.
