BOLTON — The Groton-Dunstable girls basketball team was hoping to create something memorable in their Nashoba Summer Basketball League finale on Monday night and they did just that. The Lady Crusaders played a perfect first half of basketball in rolling to a 28-4 lead, en route to a 36-21 win.

Groton-Dunstable put together two big runs that keyed their outstanding first half. Led by Mandy Woitowicz and Eva Mahan with four points apiece, the Lady Crusaders shut down the Nashoba offense for the first seven minutes and bolted out to a 10-0 lead. Groton-Dunstable played aggressive defense and didn’t allow the Nashoba offense to get set; they forced Nashoba to take outside shots which weren’t falling.

Nashoba finally got on the board with 13 minutes remaining in the first half when Madison Hawkins converted a steal into a lay-up. Less than a minute later, a drive by Rebecca Krantz drew the Chieftains to within 12-4.

Groton-Dunstable simply took off over the remainder of the half, finishing with a gorgeous 16-0 run. They shined in all departments as they played air-tight defense, moved the ball offensively and scored in a variety of manners.

Kathryn Falco (five points, two steals) got the flurry started by draining a long three-pointer. Sandra Lanier (seven points) hit a free throw and finished off a tough drive to make it 18-4. After Falco scored on a lay-up, Woitowicz and Lanier hooked up for a pair of pretty fast break baskets, Woitowicz finishing off the first one after taking a pass from Lanier, and the two reversing roles on the second. When Woitowicz buried a 17-footer, and Mahan connected on a hook shot, Groton-Dunstable went to halftime in total control.

While they played well at the offensive end, the Lady Crusaders’ large lead was keyed by a harassing defense, which featured nine first-half steals.

Nashoba looked like a totally different team to start the second half as they scored the first eight points to draw to within 28-12. Katherine Polido led the way with a pair of baskets, converting after hauling down an offensive rebound, and adding a 17-footer.

Lauren Rooney (six points, two rebounds, two steals) ended the Lady Crusaders’ drought by hitting a turnaround jumper, but Nashoba kept coming, scoring seven unanswered points to cut the lead to 11 at 30-19. That forced Groton-Dunstable to call a timeout with 11:46 remaining in the game.

Groton-Dunstable regained their intensity at the defensive end and allowed just two points the rest of the way.

Woitowicz was the catalyst in the victory with a superb all-around effort, finishing with ten points, six rebounds and a strong floor game at point guard. Mahan provided strength in the paint with six points, seven rebounds and two steals. Gin Rooney (four steals) and Jenny Moore (two points, two rebounds, two steals) were instrumental in the strong defensive effort.

Polido led Nashoba with seven points, followed by Rebecca Krantz with six points, Hawkins with four points, three rebounds and three steals, and Colleen Frost with two points and four rebounds.
