Rosario, who has already given a commitment to Rutgers, rattled off four three-pointers in the game. He didn't play the final quarter but finished the game with 20 points to lead his team.
His smooth deliver and solid guard play helped the Playaz jettison to a 36-22 halftime advantage. By the time Rosario was finished playing, the Playaz junior squad had elevated the lead to 52-33.
"I felt good in the first quarter, I had my shots," Rosario said. "I had plenty of chances to take the open shot."
Jimmy Salmon's Playaz Club was able to utilize all nine players he brought for the day. Besides Rosario, big man Austin Johnson scored 12 points, most of them around the rim. Guard Wayne Mack added 10 points while Trevor Cummings scored eight points.
