The Prep, usually dangerous from three-point territory, shot a ghastly 5 for 26 from beyond the arc. St. Joe's Hanif Sutton, a 5-foot-9 senior guard who covered the 6-5 Notre Dame commit Steve Vasturia most of the way, headlined that effort.
"He's a lot taller than me," Sutton said of Vasturia. "I tried to get underneath him as much as I could. And my quickness kept him from driving past me."
Wing guard Ja'Quan Newton bunched 11 of his 15 points into the second half; forward John Davis posted 12 points and 10 rebounds; and guard Lamarr Kimble hit two treys en route to 10 points.
"That loss to La Salle really opened our eyes," Davis said. "Before that, we kind of had the mind-set that no team in the league could beat us."
Sutton, who talked afterward with Princeton assistant Dan Geriot, scored six of his eight points in the second quarter. He added five rebounds and three assists.
"Defense is a lot of about your will to do it," the second-year starter said. "It's about wanting it more than the other guy."
Also contributing for the Saints (9-4 overall, 5-1 league): Tony Toplyn (eight points, five boards) and subs Jamal Custis (six, four) and Troy Harper (five, three).
For the Prep, which slipped to 10-3 and 3-1, Vasturia (6 for 17 from the field) and Miles Overton (6 for 15), who has committed to Wake Forest, struggled mightily.
"Their defense was terrific, and we didn't match their intensity," Hawks coach Speedy Morris said. "That was probably the worst loss we've had in my 12 years here."
