Two local football teams will open the postseason Friday night, while a third ended its regular season in fine style.

Cape Elizabeth will take part in the playoffs for the seventh year in a row after a 3-5 campaign gave the Capers the eighth and final spot in Western Class B.

Last Friday, Cape Elizabeth traveled to Mountain Valley and came away with a 32-6 loss.

Mountain Valley (3-5) punted on its first series, then scored on three of the next four possessions in the first half to take command.

Cape Elizabeth relied on the running of Nick Moulton (80 yards, 19 carries) and Tony Moulton (30 yards, nine carries) throughout the first half. Capers’ QB Noah Wolfinger was 5-for-15 for 62 yards, the longest being a 39 yarder to Cam Wilson in the third quarter. The 84-yard drive was caped off by Nick Moulton diving over from a yard out for Cape Elizabeth’s lone score.

“It has been a challenging year in terms of dealing with multiple injuries each and every week,” said Capers coach Aaron Filieo. “Having said that, I continue to be impressed and admire the effort and resilience of this team. Each and every week they set out and achieve competitive greatness. Other than this past weekend we have been in every game with a chance to win.”

Cape Elizabeth goes to top-ranked 7-1 Marshwood for the quarterfinals Friday night. On Oct. 5, the Capers lost at the Hawks, 20-0. This is the teams’ first playoff meeting.

“Our record nor the scores of our games mean anything now,” said Filieo. “Everyone is 0-0 and has a shot at advancing. We are ‘business as usual’ and will once again play hard.”

In Western A, Scarborough finished with a 43-18 win at Gorham to wind up 6-2 and third in the region. The Red Storm was up 28-6 at halftime and never looked back. Quarterback Dillon rush had three rushing touchdowns and threw for another to Ben Greenberg. Dan LeClair and Merrick Madden also had rushing TDs.

Scarborough will host No. 6 Sanford (5-3) in the quarterfinals Friday at 7 p.m. The teams didn’t play this year and have no postseason history.

“We are very excited to be in the playoffs for the third straight year and pleased to have a home playoff game at Scarborough,” said Red Storm coach Lance Johnson. “The team has worked hard and we are playing well in all three phases of the game. The matchup with Sanford is going to be challenging. They have two superb running backs who run with great effort. We look forward to the challenge.”

South Portland will not take part in the playoffs, but the Red Riots made a mighty statement in their regular season finale Saturday, shocking visiting Portland, 19-6, in the “Battle of the Bridge” to end up 2-6.

After a scoreless first period, South Portland went up 13-0 as quarterback Duncan Preston scored on a short run and Preston hit Joey DiBiase with a 50-yard TD pass. The Bulldogs pulled within 13-6 by halftime and after a scoreless third quarter, the Red Riots delivered the coup de grace in the fourth on a 26-yard scoring run by DiBiase.

“It felt great,” said South Portland coach Steve Stinson. “It was a well deserved win for the kids. We did a nice job in practice all week talking about what we could accomplish by winning the ‘Bridge’ game. The kids came out and played physical and with confidence. A lot of guys knew it was the last game they’d play. It was our most emotional game of the year. Field conditions played a role for both teams, but we finally broke through. The kids were very excited to win. For a 1-6 team to beat a 5-2 team by two TDs was something to enjoy.”

The Red Riots should bounce right back in 2013. Unlike this fall, when they basically started over due to graduation, next year’s squad will have the benefit of experience.

“We had so many holes to fill this year, but we’ll be one of the most experienced teams next fall,” said Stinson. “We’ll have a big senior class. We bring back nine starters on both offense and defense. A win like this sets us up for a good winter, spring and summer. My job will be to develop the linemen. We have great size and great skill players who are ready. They just need to get bigger, faster and stronger.”
