RiVERSIDE, Calif. - UC Santa Barbara will need to clinch the No. 1 seed in the Big West Tournament when it hosts Cal Poly next weekend in Santa Barbara. 

The Gauchos (17-3 overall, 11-3 Big West) dropped a 68-52 game at UC Riverside (11-7, 6-4) on Saturday night, setting the stage for the clinching game at home next weekend.

Zyon Pullin scored a game-high 21 points to lead the Highlanders. 

UCSB, which was paced by JaQuori McLaughlin and Amadou Sow with 17 apiece, trailed by 12 points at halftime and never got close enough to make it a game. 

Jock Perry had 11 points, while Flynn Cameron added 10 points for Riverside. 

The loss ended the Gauchos' school record 13-game winning streak. It also set them up to secure the No. 1 seed at the Big West Tournament with one win next weekend when they host Cal Poly on Friday and Saturday, Mar. 5-6 at the Thunderdome in a pair of 5:00 p.m. games.
