Belfield had 17 points and Willis contributed 16, along with nine assists and six rebounds. Darris Santee added 13 points and five rebounds as UNLV improved to 5-0.
The 4-1 Cardinals got 18 points from Edgar Sosa, 13 from Samardo Samuels, and 10 points and 11 rebounds from Rakeem Buckles.
After trailing 56-38 12:02, Louisville pulled into a 62-62 tie with 5:29 left when Sosa hit a shot from long range. But the Cardinals' rally stalled and the Rebels ran their lead back up to 72-66 with 1:59 to go on a pair of Santee free throws and Buckles iced it by making it an eight-point game from the free-throw line with 30 seconds remaining.
