SEATTLE (AP) - Mattise Thybulle scored 18 points and freshman Jaylen Nowell added 14 points and a team-high nine rebounds to pace Washington to an 80-62 victory over Washington State in a Pac-12 Conference game on Sunday.
Washington (15-6, 5-3) used an 18-0 run to open a 45-30 halftime lead, but the Cougars answered with a 14-4 run to start the second half, pulling within 49-44 on a jumper by Viont'e Daniels. Thybulle was fouled on a 3-pointer and added the free throw to push the lead to 53-44.

Robert Franks had 16 points and Drick Bernstine added 13 for the Cougars (9-11, 1-7). Noah Dickerson added 13 points and Nahziah Carter 11 for Washington.
Washington State, which entered second in the nation and first in the Pac-12 with 11.9 3-pointers per game, was just 6 of 24 beyond the arc against Washington's zone defense. The Cougars also committed 15 turnovers.
The Huskies appeared to gain control with the 18-point run late in the first half. The Cougars, who trailed by as many as seven early, went in front 28-27 on a 3-pointer by Daniels with 9:05 left in the half. Jaylen Nowell answered with a jumper to trigger the spurt, which included three consecutive 3-pointers by Dominic Green.
