HOPKINTON – Dover-Sherborn’s field hockey team twice faced a deficit against signature foe Hopkinton in the cutthroat Tri-Valley League Wednesday night. “I kind of came at them hard in the first half,” McGill said. Dover-Sherborn quickly cleared it, moved upfield, and Bent finished off the sequence for the 3-2 lead with 45 seconds left in the frame. ”Curtin did well to keep Dover-Sherborn off the board from there, but Hopkinton struggled to generate many offensive chances the rest of the way. Elyse Bissada scored the first goal for Dover-Sherborn, giving the Raiders three different goal-scorers on the night.
