LOS ANGELES — Washington State couldn't make a dent against UCLA's defensive pressure most of the game. When the Bruins let up, the Cougars unleashed a stunning barrage of 3-pointers and still lost.

The fifth-ranked Bruins knocked the No. 4 Cougars from the unbeaten ranks Saturday with an 81-74 victory led by freshman Kevin Love's eighth double-double of the season.

"I'd never seen anything like that," Love said about the Cougars' seven 3s in the final 1 1/2 minutes.

"Wow," marveled teammate Darren Collison.

Love had a career-high 27 points and grabbed 14 rebounds, while Collison added 18 points and the Bruins (16-1, 4-0 Pac-10) won their ninth in a row and seventh straight over the Cougars.

"For college, it's probably my best game overall," Love said.

Derrick Low scored 24 points after getting nothing in the first half for Washington State, which saw its best start in 91 years ended. The Cougars committed 13 turnovers, nine in the first half.

"Once you get in a little hole against a team as high-caliber as them, it's going to be tough," Low said. "They're what a championship team is. That's how we want to play."

The Cougars (14-1, 2-1) still have just one victory in 51 games at UCLA. They had lost the previous three meetings in Westwood by a combined eight points.

"We could not get stops," Washington State coach Tony Bennett said.

The Cougars made it close at the end with nine 3-pointers — five by Low — over the final 5:48. Most of the 3s were contested, but the Cougars' accuracy shocked the crowd of 12,590 and the Bruins.

"We were doing what we had to do in a situation that we didn't want to be in," said Taylor Rochestie, who had 13 points. "That's not how good teams win."

The Cougars called timeouts during their shooting spree.

"I told guys, 'Nice flurry on the 3s, but don't lose the meaning of the message,"' Bennett said. "When it was really game time, we couldn't hang in there. If we're not really clicking, we're so vulnerable."
