Van Treese, who started in place of injured power forward Rakeem Buckles, led Louisville with 12 points and 14 rebounds. He made 6 of 10 shots, and grabbed nine offensive rebounds to give Louisville's offense key second chance opportunities.
Preston Knowles and Terrence Jennings also scored 12 points for Louisville. Knowles, who sat out most of the first half with three fouls, scored nine points in the last four minutes, including a key three-pointer with 2:16 that gave UofL a 74-65 lead, to secure victory for the Cardinals.
Though Louisville trailed 41-38 at halftime, the Cardinals outlasted USF with excellent three-point and foul shooting. Louisville made 9 of 21 three's, and hit an outstanding 23 of 26 free throws. Mike Marra made 3 of 7 three-pointers, while Dieng made all six of his free throws.
Marra finished with 11 points, while Dieng, who blocked five shots, and Peyton Siva each contributed 9 points. George Goode also came off the bench to hit two three-pointers to keep Louisville close before the break with Knowles, Louisville's leading scorer, on the bench.
South Florida forward Augustus Gilchrist led the Bulls with a game-high 25 points.
The road gets tougher now for Louisville, who improved their Big East record to 2-0 with a win over South Florida. The Cardinals travel to No. 7 Villanova Wednesday.
