LEWISTON — A mistake on a power play early in the game nearly cost Falmouth a trip to the Class A state final. The Yachtsmen’s prowess with an extra skater in the third period got them there.

Hugh Grygiel scored his second goal of the game and fifth in two playoff games on a wrist shot on a power play with 3:09 to play in regulation to help Falmouth upend Scarborough 4-3 in the Western Class A regional final at the Androscoggin Bank Colisee on Tuesday.

Grygiel’s 27th tally of the season came 17 seconds into a power play that began just after Falmouth scored the equalizer on a rebound in front of Scarborough goalie Dalton Finley. That goal, by Isac Nordstrom, came after a keep-in at the right point by defender Ethan Low. In the scrum in front of the cage after the goal crossed the line, officials assessed a penalty to Scarborough’s Garrett McDonald, immediately putting the Yachtsmen on their fourth power play of the night.

And it took just 17 seconds for it to pay off, as Gryigiel ripped a wrister short-side blocker. Dane Pauls finished with 22 saves for Falmouth, including a stellar kick save as the Storm pressured deep in the zone trying to knot the score late in the third. At the other end, Finley stopped 33 of the 37 he faced in the loss.

Scarborough started the first period outskating the Yachtsmen and beating the No. 2 seed to the puck. Then, Falmouth started to take the body, and things changed quickly. The pressure created a couple of scoring chances, one of which found the back of the net behind Finley at the 6:08 mark.

It took five minutes and a shorthanded chance, but the Red Storm retaliated. Trevor Murray raced into the zone after a loose puck as Pauls flew out of his cage to intercept the drifting disc. The two collided and the puck slipped away from Pauls. An alert Jake Gross charged in and fired it into an empty cage to knot the game at one. It took Falmouth just 1:55 in the second to reestablish its one-goal lead.

This time, Tyler Jordan finished a rush with a shot that looked at first as if it was intended to go high glove, but instead slid along the ice and beat Finley 5-hole. It then took the Red Storm just 38 seconds to again tie things up as Cam Loiselle lofted a shot into the cage after a defensive-zone turnover by the Falmouth defense.

The Storm grabbed their first lead of the game at 5:37 of the middle frame on a power play, as Nick Bagley sniped the top corner of the cage behind Pauls on a slick feed from Murray, who had traded places at the left point with Bagley.
