It was Charlie Bryant's time to shine for the Jackets as he led the way with 165 yards on 20 carries and two touchdowns.
"We had a real good overall effort tonight," Black said. "Our kids played real well right from the start. Charlie Bryant really came out and had a good game for us too."
After starting the season 2-0, the Mountain Lions have found the going tougher of late, dropping three straight by a combined score of 132-26. One loss was to Class 2A Middlesboro and another was to 1A power Lynn Camp.
Pineville scored less than three minutes into the game to take an early lead, but as it turned out, that was the only score the Mountain Lions would manage.
The Lions got on the board with 9:12 to play in the opening quarter on a 12-yard pass from David Adams to Zac Churchwell. Matt Combs booted the point after for a 7-0 Mountain Lion lead.
Williamsburg countered three minutes later and tied the game on a 22-yard touchdown run from Bryant.
Five minutes later it was quarterback Thomas Frazier hooking up with Chase Hamblin on a 30-yard touchdown strike to give the Jackets a 15-7 lead at halftime.
Frazier finished the game 15 of 20 passing with 165 yards and one touchdown while also rushing for one score.
Less than three minutes into the second half it was Frazier again causing trouble for the Mountain Lions. This time Frazier ran the ball in from nine yards out to extend Williamsburg's lead to 22-7 with nine minutes to play in the third quarter.
"When we came out in the third quarter we knew what we had to do to win this game and we did it," Black said. "We played very efficiently on the passing game and the running game and that's what we needed to do."
In the third quarter it was Bryant punching it in from three yards out for his second score of the game to stretch the Jacket's lead to 29-7 with 2:49 yo play in the third quarter.
The Mountain Lions gave Williamsburg it's next two points, as the snap on a punt attempt sailed over the head of the Pineville kicker for a Jackets' safety, and a 31-7 lead.
Even the Williamsburg reserves were able to do some damage in the fourth quarter when Jordan Hughlett hit Thomas Rains for a touchdown for the Jackets' final score of the game to put the lead at 37-7 with 2:32 to play.
"It is really good to get that first district win under your belt," Black said. "We still need to improve on some of our mistakes.
Williamsburg will visit Somerset on Friday, while Pineville goes out of district, traveling to Betsy Layne.
