AMES, Iowa (AP) - Scott Christopherson scored 25 points, Chris Allen added 16 and Iowa State beat Oklahoma 80-69 on Saturday for its fifth win in seven games.
Melvin Ejim had 10 points and 14 rebounds for the Cyclones (19-8, 9-5 Big 12), who've won five straight league games at home for the first time in eight years.

Cameron Clark led five in double figures with 16 points for the Sooners (13-13, 3-11), who've lost six straight and have fallen to .500 for the first time this season.
