Louisville's objective against South Florida on Saturday was more about firming up its defense rather than avenging its last home loss. Either way, the No. 3 Cardinals achieved both goals in convincing fashion. Senior guard Peyton Siva scored 17 points to surpass 1,000 for his career and contributed a team-high three steals as Louisville held South Florida to a season-low 27 percent shooting for an easy 64-38 victory that also marked the Bulls' second-lowest point total in school history.
