Antoine Williams chipped in 15 points and four steals, and Jaquan Pitts recorded 10 points in a solid all-around effort for the Hornets (9-1), who stretched their winning streak to eight games.
"It's been a nice start for us," said Pemberton coach Roy Heck. "We don't want to get too far ahead of ourselves, but we have some very versatile players who have been contributing and playing well."
Friday night was the debut of 6-foot-7 center Jean Lebrun, a transfer from Haiti with endless promise for the Hornets.
Lebrun checked in for the first time with eight seconds left in the third quarter and played most of the final period, recording three rebounds and two blocks while missing the only shot he took.
Lebrun was a spectator as Pemberton built a substantial lead through the first three quarters. After outscoring Cinnaminson by 14-4 in the second period, the Hornets went into the locker room ahead by 35-19. Thanks largely to a smothering defensive effort, the lead ballooned to 24 before the Pirates (3-6) made a late run to keep the game respectable.
Matt Gono and Jack Hart each recorded 16 points for Cinnaminson.
"I was proud of our effort - particularly at the end," said Cinnaminson coach Mike Fries. "But the third quarter killed us. We had too many turnovers."
