After enduring four games in three days, the Martha’s Vineyard Youth Soccer under-15 team defeated the Dorchester Lions 2-1 Sunday in the finals of the Massachusetts Tournament of Champions to bring home the state title — a prize that’s eluded them throughout each of their nevertheless-successful seasons.

Colin Cameron notched the first goal less than two minutes into the game to put the team on the board. Timmy Roberts landed the game-winner in the second half.

The tournament “had a good feel to it,” assistant coach Matt Poole told the Gazette. The good omens appeared before kickoff at Citizens Bank Fields at Progin Park in Lancaster, as the teams warmed up beneath a stunning double rainbow.

The U-15s took to the fields early on Friday, defeating Wilmington 1-0 and following it up with an afternoon 1-0 win over Dorchester. On Saturday they played Worcester, taking a 3-0 victory to send them into the tournament semi-finals against Brockton.

Sunday brought an 8 a.m. kickoff for the Brockton game, but the early start time had little effect on the Vineyard team, as they took a 3-0 lead. Brockton rallied to tie the game and send it into two five-minute overtime periods. Brandon Dwane, who had already contributed a goal, notched two more during overtime to give the U-15s a 5-3 win and a berth in the finals.

It wasn’t the first time the team, who have been led by head coach Esteban Aranzabe and Mr. Poole from the beginning, had made it to the title game. When they were still U-11s, coming off an undefeated season, the boys met Cambridge in the finals, and “got killed,” Mr. Poole recalled. They made two more trips to the tournament in ensuing years — no easy feat in itself — but never advanced to the big game.

But the talent of the U-15s has been there from the start, well before that first trip as U-11s. And this year, as the players entered high school and added the challenges of interscholastic competition to their schedule — three of the boys were freshman starters on the varsity team — they gained even more experience and confidence. The latter would come in handy during the tournament, where the team played in the U-16 age group against older opponents.

“The really noteworthy thing [is that] it’s not like we just dropped out of the sky and did this,” Mr. Poole said.

Scanning the U-15s record from this season, it seems unfathomable that another group could have taken their spot in the finals. The team scored 67 goals in the regular season, before entering the MTOC. They allowed only one, in a 1-0 loss to Dartmouth at season’s midpoint (this was also their only regular season loss). Last year, Dartmouth denied the U-15s a spot in the tournament, taking an overtime win to move on to states.

“Dartmouth went to the state tournament, and we went fishing,” said Mr. Poole.

This year, they’ve caught the big one.

The U-18 soccer team advanced to the semi-finals of their age group in the Massachusetts Tournament of Champions, taking wins over Middleboro and Cape Ann and drawing with Dorchestr before falling 2-1 to Newton.
