It’s the game that most prognosticators said would determine the Massachusetts Division I state lacrosse champion. On Saturday afternoon at 3:30, the Dragons will move one step closer to earning their eighth state crown when they travel to Billerica for the Division I state semifinals against the No. 2 seeded Indians.

The hosts currently sport a 20-2 record and moved on to the confrontation with Duxbury by beating Acton-Boxboro, 15-6, on Wednesday afternoon, while the Dragons were taking care of No. 6-seeded Lexington, 13-4.

Outside of Duxbury’s three out-of-state loses, Billerica gave Duxbury its most difficult time this season, holding a three-goal lead after three quarters, but succumbing to the Dragons in the final 12 minutes for a 12-9 loss in the fourth game of the season.

“I don’t expect to have a run like that again in the fourth quarter,” said Coach Chris Sweet about his team’s first game with Billerica. “That game was a good sounding board for us. We learned what areas we needed to improve on and I think we have responded to that.”

In the team’s first two tournament games, neither opponent has presented much of a challenge to the Dragons. Following its 16-0 romp over Natick, the Dragon offense continued to pile up the goals, as it scored six in the first quarter and never looked back against Lexington.

While the same type of offensive explosion demoralized Natick, it didn’t seem to curtail the Minutemen’s enthusiasm, as the players continued to cheer on their teammates despite Duxbury’s dominance in the first 12 minutes.

It was Kane Haffey’s chance to shine, as the senior captain scored six goals in the win, while Will Siefert chipped in with a pair. Seamus Connelly, Bryan Barry, James Burke, Paul Hellar, and Tim Harrison also got on the scoreboard for the Dragons.

“Lexington did some things that allowed us to go one-on-one right away,” said Sweet. “In the second quarter they made some adjustments and we kind of got lazy on offense. Then we woke up in the fourth quarter and started to play our kind of game. We can’t afford lulls like that against Billerica. We won’t be able to pad our lead early on.”
