UNLV led one time in the game, at the 12:39 mark of the first half, when it went up 13-11. But the Gauchos went on runs of 8-0, 20-8 and 34-16 to close out the half.
UNLV's offensive woes wore on the Runnin' Rebels' effort on the defensive end as well.
The Gauchos (2-0) shot a scorching 62.5 percent from the field (15 of 24) in the first half and led 45-29 at halftime. UCSB finished the game shooting 29 of 52 (55.8) from the field, including 9 of 14 (64.3) on 3-pointers. The Gauchos also out rebounded UNLV, 41-33.
Kyle Boswell added 19 for the Gauchos, after shooting 5 of 7 from beyond the arc.
