Chris Patton and Chris Harriel had a team-high six points for Riverside (2-8), which shot 19 percent from the field and was 1 of 14 from 3-point range. The Highlanders' starting five -- Harriel, Robert Smith, Lucas Devenny, Davin Guinn and Josh Fox -- were a combined 4 of 28 for 12 points.
The Highlanders eclipsed the previous school record for fewest points in the shot-clock era -- set Nov. 14, when Fresno State beat them 39-30. The low-water mark before that game had been a 56-35 loss to USC last season.
Riverside made only five of 29 shots in the first half. It was more of the same in the second half, as USC (4-6) opened up a 44-point cushion with an 18-1 burst.
