PULLMAN, Wash. - Darren Collison scored all of his 18 points in the decisive second half and freshman Kevin Love added 16 points and nine rebounds to lead No. 5 UCLA to a rugged 67-59 victory over reeling No. 17 Washington State on Thursday night.

Collison made all seven of his free throws and coolly shook off 0-for-4 shooting in the first half as the Bruins (21-2, 9-1 Pac-10) stayed one game ahead of Stanford atop the Pac-10. UCLA, which has appeared in two consecutive Final Fours, remained on its best start since the 1994-95 team went 32-1. That team won the NCAA title.

Kyle Weaver scored 13 points and Aron Baynes added 11 despite foul trouble for the Cougars (17-5, 5-5), who are now 1-70 against teams ranked in the top five. Washington State, not so long ago a top-10 team, lost for the third consecutive time and for the fifth time in eight games.
