FARMINGTON — Mt. Blue rallied from a 20-point halftime deficit to defeat Cony 35-34 with 47 seconds remaining in the game Friday night at Caldwell Field in a Class B North football quarterfinal game.

Mt. Blue trailed 34-21 with 7:01 remaining in the fourth quarter when Nate Pratt-Holt raced 35 yards around the left end on a reverse. Ryan Pratt hit Makao Thompson for a two-point conversion to cut Cony’s lead to 34-29 setting the stage for a frantic finish.

“We got some breaks and made some great plays,” Mt. Blue coach Jim Aylward said. “We showed a lot of heart coming back from 20 points down at halftime.”

On their next possession the Rams moved the ball to the Mt. Blue 34 before the drive stalled on a sack and a pair of incomplete passes, giving the Cougars the ball with 4:26 remaining in the game and 66 yards from the end zone.

Ten plays later, Mt. Blue appeared to be in trouble when the Cougars faced a fourth-and-goal at the 10 with less than a minute left. Mt. Blue featured the running of back Christian Whitney (18 carries, 131 yards) on the game-winning drive.

On the Cougars’ final play, quarterback Ryan Pratt (10-16-2, 160 yards), found Pratt-Holt in the left corner of the end zone for the touchdown pass, giving Mt. Blue a 35-34 lead.

“It was either going to be a jump ball play or a stop,” Pratt-Holt said. “Ryan gave me the signal for a stop and made a great throw.”

Mt. Blue (6-3), the No. 4 seed, advances to face No. 1 Brunswick (7-1) in the semifinals Friday in Brunswick. Cony’s season comes to a conclusion at 4-5.

Cony took control of the game in the first half behind the running of Reid Shostak (32 carries, 144 yards), who finished the game with three touchdowns, coupled with the outstanding passing of quarterback Taylor Heath (14-24-2, 255 yards).

The crowd was silenced early in the third quarter when Mt. Blue running back Alex Gilbert took a hard hit while running around the left corner. Gilbert was taken from the field on a stretcher to Franklin Memorial Hospital for observation.
