PULLMAN, Wash. - Washington State was battling the loss of two key players and a two-decade history of losing at home to No. 23 UCLA.
But the Cougars got 20 points and 11 rebounds from Brock Motum and shocked the Bruins 73-61 on Wednesday night.
The win by the last-place Cougars broke a 19-game home losing streak to the Bruins that extended to 1993.
Royce Woolridge added 19 points for Washington State (12-18, 3-14 Pac-12), which also broke a nine-game losing streak that had put coach Ken Bone on the hot seat.
"It's nice to see these guys rewarded with a win," said Bone, whose team has repeatedly lost games in the second half this season. "It's a huge confidence-builder."
Jordan Adams scored 18 points for UCLA (22-8, 12-5), which had won four straight and began Wednesday tied with Oregon for first place in the Pac-12.
"We didn't come out with the emotion and intensity that we needed," UCLA coach Ben Howland said. "We didn't have the sense of urgency when so much was riding on the line for us."
Shabazz Muhammad added 14 points for UCLA on 4-of-19 shooting.
Washington State played without Mike Ladd (knee injury) and DaVonte Lacy (knee injury), their second- and third-leading scorers. Bone said Lacy is out for the rest of the season.
It didn't seem to matter, as the Cougars sliced up the Bruins inside for easy layups much of the game.
"We set good screens," Motum said. "Our guys were wide open for baskets."
• Stanford 83, California 70: In Berkeley, Calif., the teams brawled in the second half, but the game wasn't close. Game details were unavailable because the game ended just before press time.

The Wildcats (19-12, 10-8 Big East) also beat then-No. 5 Louisville and then-No. 3 Syracuse and have put themselves in solid shape for at least an NCAA tournament at-large bid.

The Billikens (23-6, 12-3) fell into a first-place tie with No. 21 VCU.
• No. 21 VCU 93, Richmond 82: In Richmond, Va., Treveon Graham scored 15 of his 21 points in the second half, including the go-ahead basket with 2:58 to play, for VCU (24-6, 12-3 A-10), which moved into a first-place tie with Saint Louis.
