Junior guard Klay Thompson scored 24 points, and host Washington State beat Gonzaga for the first time in three years, 81-59 Wednesday.

Thompson added six rebounds, six assists and seven steals for Washington State (6-1), which started the game on a 26-6 run. Faisal Aden scored 14 points and Patrick Simon added 11 for the Cougars.

Gonzaga (4-4), which is off to its worst start in coach Mark Few's 12 seasons, came back with an 18-5 run to finish the first half, and trim Washington State's lead to 30-24.

Center Sam Dower had 11 points and five rebounds as Gonzaga's only double-figure scorer. Guard Steven Gray, who entered the game averaging 20 points per game, finished with seven points on 2-of-10 shooting and seven assists.

Gonzaga shot 19 for 48 (39.6 percent) from the field, including 4 of 18 (22.2 percent) on 3-pointers.

Washington State, meanwhile, shot 30 for 60 (50 percent) and 11 for 24 (52.4 percent) from beyond the arc. Gonzaga also struggled with its 3-point defense in losses to San Diego State, Kansas State and Illinois.

Gonzaga’s treacherous non-conference schedule continues Saturday at Notre Dame, and the Bulldogs still have Baylor, Xavier and Oklahoma State this month, plus games against Wake Forest and Memphis.
