LOS ANGELES — Johnny Juzang scored a career-high 17 points and UCLA rolled to a 91-61 victory over Washington State on Thursday, extending its overall winning streak to five and its home-court victory streak to 14.

The Bruins (10-2, 6-0 Pac-12) remain the lone undefeated team in league play. They are off to their best start in the Pac-12 since going 7-0 to begin the 1993-94 season.

Tyger Campbell and Jaime Jaquez Jr. added 16 points each for the Bruins. Cody Riley had 12 points and six rebounds. UCLA got off to strong starts in both halves, opening the game with eight straight points and the second half with six straight. They held the Cougars scoreless during those runs.

The Cougars (9-3, 2-3) dropped their 10th straight at Pauley Pavilion. They’ve lost three of their last four overall.

Isaac Bonton led the Cougars with 23 points, their only double-figure scorer. They were held to 23 points in the second half and made just one field goal over the final seven minutes.

Washington State starts three freshmen and a sophomore along with senior Bonton, their leading scorer at 17.7 points. The combined 26 starts by Efe Abogidi, Andrej Jakimovski and Dishon Jackson are fourth-most in Division I.

The Cougars visit Southern California on Saturday to wrap up a stretch of four straight road games.
