Marquetti is a 2014 Scout three-star recruit who will be able to make an immediate impact for the Trojans.
"Malik is a versatile player that can play multiple positions," USC coach Andy Enfield said in a statement released by the university. "Offensively he can score and make plays for his teammates. His long wing span and toughness make him an excellent defender and rebounder."
Marquetti, 6-foot-6 185-pounds, is considered a top 'sleeper' prospect in the 2014 class by Scout's basketball recruiting analysts -- bursting onto the scene his senior season.
