ST. CHARLES – As Geneva’s premier offensive weapon, sophomore Nate Navigato serves as Chris Parrilli’s defensive prey in practice, sharpening Parrilli’s tenacity for defensive assignments against opponents’ top scorers.

“It’s hard,” Navigato said of dealing with Parrilli in practice. “He gets kind of annoying after a while. But it helps. He’s a good defender. He’s our best defender. He amazes me.”

Parrilli played his defensive role to near perfection Friday, taking the lead in forcing St. Charles North standout Quinten Payne into an uncharacteristically quiet night as Geneva controlled the Upstate Eight Conference River contest, 51-40.
