PULLMAN, Wash. — Andrew Luck threw two third-quarter touchdown passes to Levine Toilolo as No. 7 Stanford beat Washington State 44-14 Saturday to extend the nation's longest winning streak to a school record 14 consecutive games.

Stanford (6-0, 4-0 Pac-12) struggled against the Cougars defense before blowing the game open in the second half. Luck, a Heisman Trophy candidate, finished with four touchdown passes, all in the second half.

Washington State (3-3, 1-2) hoped to get a boost from the return of starting quarterback Jeff Tuel. But they had little success against a Stanford defense that is allowing just 10 points per game.
