DUMFRIES, VA., DEC. 14 -- Despite an outstanding performance by Potomac guard Marty Warner, Fauquier shut down the rest of the Panthers offense and upset the defending Northwest Region champions, 83-71, tonight at Potomac.

Warner scored 38 points, but his offensive proficiency left his teammates watching.

"When you have one guy doing so much, the other guys just kind of stand around a lot," said Potomac Coach Kendall Hayes. "He was just hot tonight."

Hot enough to give Potomac (1-1) a 10-point lead -- its biggest of the night -- 15 seconds into the second quarter. But Fauquier scored the next 11 points and outscored the Panthers by 27-14 in the quarter to take a 43-39 halftime lead.

The Falcons (2-0) used a balanced attack to offset Warner. Five Fauquier players scored in double figures, led by junior forward Duane Gillman's l8 points. Joe Jones and Marquis Ferguson each had 14 points, Calvin Yates 13 and Brian Marshall 10.

Jones's exit because of foul trouble left the middle open for the Panthers, who instead chose to take long jumpers and fell behind by 59-54.

But the Panthers ended the quarter in a flurry with Warner sinking a jumper and making a foul shot. It carried to the fourth quarter as Potomac scored the first six points to tie the game at 59.

But the quicker Falcons made a decisive run by repeatedly driving the lane to score seven straight points in the next minute.

Yates took the ball to the basket, scored and was fouled by James McNeal. Gilliam scored and Yates again was fouled driving to the basket.F (2-0) -- C. Marshall 6, Robinson 2, B.
