At Androscoggin Bank Colisee, Lewiston

CLASS A

Scarborough (13-5-3) vs. St. Dom’s (17-2-1)

Saturday, 6 p.m.

Key for Scarborough: The Red Storm, who were seeded No. 4 in the West, play a strong defensive game anchored by senior goalie Ben Bragg (1.40 goals-against average; .941 save percentage). They also feature a couple of solid defensemen in Sean McDonald and Kevin Smith. Defenseman John Callahan can create offense. Most goals come from the top line of Matt Caron, Sean McGovern and Cam Nigro, although second-liner Braeden Kane is a threat. Scarborough is solid on the power play with four postseason goals (and three more while skating four-on-four). The Red Storm lost their only game against St. Dom’s this season, 2-1 on Dec. 10.

Key for St. Dominic: The Saints were the top seed in the East and sport the state’s best Class A record, their only losses coming to Falmouth. While this is Scarborough’s first trip to the Class A title game, this is the Saints’ third trip to the final in the last four years. St. Dom’s has not won the state championship since back-to-back titles in 1999 and 2000. St. Dom’s is explosive – out-scoring opponents 82-37. The Saints’ top line is led by two Travis Roy Award semifinalists – Brad Berube (16 goals/24 assists) and Caleb Labrie (15/13). St. Dom’s used three goalies during the season, but Kyle Welsh has emerged in the playoffs. He made 35 saves in a 5-3 win over Lewiston in the East title game.

CLASS B

Gorham (14-5-2) vs. Messalonskee (19-1) Saturday, 1 p.m.

Key for Gorham: The Rams, the sixth seed in the West, have recorded three upsets in the playoffs and the fourth would be the biggest of all. Powerful Messalonskee topped Gorham 6-1 in the state final last year. But Gorham has shaken off losses before, like the 6-0 defeat to Kennebunk to end the regular season. On Wednesday, Gorham beat Kennebunk 5-4 for the West title. While the Rams can spread out their scoring, the top line of Travis Mansir, Jordan Ward and Carl Bear will be heavily relied upon. Carter Landry keys the second line. Matt Hooker has come up big as a defenseman, and goalie Noah Bird has been hot in the playoffs.

Key for Messalonskee: The Eagles, easily the top seed in the East, are heavily favored and will be tough to beat if they play their usual dominant game. Messalonskee’s only loss in the last two years came in December against Class A power Bangor – a loss the Eagles avenged on Feb. 2, 4-2. Messalonskee’s strength is its top line, which has combined for 102 goals. Jared Cunningham (29 goals, 48 assists) is the playmaker, alongside Brandon Nale (35/39) and Jake Dexter (38/33). The Eagles’ other two lines are not as high-scoring, but they are solid and keep the puck in the opponents’ end. Goalie Elija Tuell has developed well in his first year.
