BANGOR — For the first time in school history, Monmouth Academy is a state basketball champion.

Junior forward Abbey Allen scored a team-high 18 points and Monmouth toppled Dexter 46-37 in the Class C girls basketball state championship game. It was the first state title for a Monmouth team in either girls or boys basketball.

The Mustangs (19-3) used a late second quarter run to power to the title. Junior point guard Tia Day added 13 points.

Monmouth started slowly as Dexter built up a 9-4 lead just two minutes into the period, but the Mustangs came charging back. Day hit the first of her two second-quarter 3-pointers as Monmouth started to find its shooting touch, setting off a 12-4 run to close out the first half.

The Mustangs took a 16-13 lead into the halftime break and held Dexter (16-5) at bay in the third quarter. Megan Peach scored 10 of her game-high 20 points for the Tigers in the third quarter, but Abby Ferland’s long jumper was followed by Julia Johnson’s 3-pointer to open the fourth, and the Mustangs were out to their largest lead of the night at 35-27. Key foul shooting by Monmouth over the final three minutes, much as it had done in the regional championship game against Old Orchard Beach a week earlier, put the game out of reach.
