Running backs Chase Arndt and Cody Spinks, meanwhile, spearheaded the Musselman rushing attack with 74 rushing yards each. Arndt also scored a touchdown, while Spinks added two TD runs.
"As a team, we are pretty dynamic," Arndt said. "We can either run or pass. Tonight, our run game was working for us."
After falling behind 17-14, the Applemen scored 21 unanswered points on a Darrin Zombro 25-yard pass from Caleb Dembeck, a Michael Keller 5-yard pass from Dombeck and a Spinks 18-yard run, his second of the day.
Dembeck, who threw for 25 TDs and nearly 2,000 yards in the regular season, didn't pass often but when he did he made it count, completing 10 of 13 for 99 yards and two scores.
"This was a big victory for us coming in at No.10," Dembeck said. "We came to play today. They are an explosive team. But we came out and probably played our best game of the year."
Dembeck also ended any chance of a Cougar (7-4) comeback in the fourth quarter when he rushed for 35 yards on a fourth-and-goal from the Capital 40 as the Applemen were leading 28-17.
The Applemen now turn their focus to two-time defending AAA champion Martinsburg, who embarrassed them two weeks with a 73-0 thumping.
"We got beat and they have a great football team," Price said. "We have to go back to work now. The kids are looking forward to it. It will be a challenge."
