AMES, Iowa - Hallie Christofferson poured in 24 points and grabbed eight rebounds to lead the No. 24 Iowa State Cyclones past the No. 16 Oklahoma Sooners 82-61 Tuesday night in Ames.

Despite Christofferson's strong play, ISU's offensive attack was far from a one-woman show. Nikki Moody added 20 points and 13 assists while Nicole Blaskowsky dropped 17 points and eight boards off the bench.

OU (14-3, 4-1) was led by Sharane Campbell's 19 points, four rebounds and four steals. Aaryn Ellenberg added 16 points while Morgan Hook chipped in 11 points and six assists.

The Sooners' offense struggled to find any consistency, shooting just 31.7 percent from the floor and 29 percent from 3-point range. OU's 14-15 from the free-throw line kept the team in the game for a while, but Iowa State was just too much.

The Cyclones (13-2, 4-1) outrebounded OU 43-22 while dishing out 20 assists to the Sooners' 12.

Next up for OU is a home showdown with rival Texas on Saturday, Jan. 19.
