PULLMAN, Wash. (AP) Luke Falk tied the school record with six touchdown passes, all in the first half, as Washington State beat Oregon State 52-31 on Saturday.
Washington State (4-2, 2-1 Pac-12), coming off an upset victory at Oregon, hadn't beaten a Pac-12 opponent in Martin Stadium since November 2013.
They have already eclipsed the three wins they had all of last season, and this was the 100th win of coach Mike Leach's career.
