Fenwick did not reach double digits until there was 3:13 left in the third quarter, as the Sachems began shuffling in their backups.
Viselli led the offense with 13 points, including three 3-pointers, while McNamara had 10 and Moore and McKenna Kilian each had eight points.
“Our game is based on defense,” said coach John McNamara. “We want to be aggressive and work hard. We have a lot of veteran players that have been through this before. We don’t feel like we are defending a title, we are going after another title.”
The Sachems will return to the court on Wednesday in Beverly against the winner of today’s quarterfinal between No. 4 Ipswich and No. 5 Winthrop. Pentucket down the gritty Tigers (18-3) 45-40 in the regular season.
“We wanted to come out, play hard and show everyone here that we can play defense and deserve to win another title,” said Moore. “We stepped up, and we want to keep playing this way through the tournament.”
