PULLMAN, Wash. (AP) - Luke Falk threw for three touchdowns as No. 15 Washington State beat Colorado 28-0 on a rainy and windy Saturday night.
Jamal Morrow rushed for 73 yards and a touchdown for Washington State (7-1, 4-1 Pac-12), which rebounded from a 34-point loss at California that coach Mike Leach called the worst game the Cougars have played in his six years there.
Phillip Lindsay rushed for 98 yards for Colorado (4-4, 1-4), which was coming off its first Pac-12 win. Lindsay came in needing just five yards to top 1,000 for the season.
The Buffaloes completed just 13 of 34 passes for 94 yards and were held to 174 yards of offense.
