The Chieftains had a pair of transition scoring chances go by the boards late in the quarter as sophomore forward Ellie Eisenklam served up a pair of blocks to turn the hosts aside.

Being the top team, Groton-Dunstable knows it’s going to get its league-mates best game. But, the Crusaders weathered the early onslaught.

The second quarter saw little scoring output from both teams as Groton-Dunstable took a 26-16 lead into halftime.

“We are notorious for our slow starts,” said Hennelly. “They had an off-night shooting — I am surprised that we were able to pull away as much as we did. Nashoba did not play as well as it usually does.”

Groton-Dunstable’s tilt with Marlboro (11-7,7-4 Mid Wach B) — will be a good tuneup for both teams heading towards the postseason.

“They are a good team,” said Hennelly, of Marlboro. “They have a couple of guards who are talented inside-out players. Marlboro will be a good test just like Nashoba was tonight. They (Nashoba) have a talented guard in Kevyn Green and a lot of other good shooters. I knew this game was not a gimme.”
