On an afternoon in which a foe was just as fast as the Dennis-Yarmouth field hockey team, what allowed the top-seeded Dolphins to survive and advance was poise. Along with a favorable spin.
Senior captain Summer Walsh knocked home the game’s lone goal in the final minute, lifting top-seeded D-Y past Foxborough, 1-0, in a Division 2 South Sectional semifinal Tuesday afternoon in South Yarmouth.
Dennis-Yarmouth (19-1-2) will play second-seeded Cohasset (19-2), a 2-0 winner over visiting Bishop Stang, for the South title Saturday in Taunton.
“[It was] a scramble, just everybody in front of the net,” said D-Y coach Mary O’Connor of Walsh’s goal
“The girls said Summer hit it in and it clipped a girl’s heel, then it kind of spun, and luckily it spun into the goal.”
Walsh said the ball “bounced off one of their heels into the net,” before adding, with relief, “you never want to have to [go to overtime].”
As O’Connor noted, Foxborough (15-4-2) had advanced to the semis with overtime wins over Martha’s Vineyard (2-1) and Dover-Sherborn (1-0). “There’s a little bit there about having that experience and [knowing] that pressure,” she said.
D-Y senior Anna McGaffigan, who assisted on Walsh’s goal, said she was “mentally preparing myself to go into a seven-a-side.”
Throughout the game, Foxborough’s Sophia DiCenso and Lily Daly were able to weave their way through the Dolphin D for good chances. D-Y allowed more penalty corners than in any other game this season. And Foxborough goalie Kelli McCarthy was exceptional.
“It was really hard, but we kept our composure on the field,” Walsh said. “We were really supportive of each other, and that’s what helped us win.”
Cohasset 2, Bishop Stang 0 — With 1:30 left, the Skippers put the ball in the care of their fastest player, senior Elle Hansen.
“She’ll push that dribble, knowing she can outrun them,” Cohasset coach Laura Giuliano said.
Hansen snuck between two defenders and lunged past the Stang goalie in trying to put the ball in the net. “When she got knocked over, I was like ‘OK, well at least that took up some time,’ ” Giuliano said. “And then we realized it went in!”
Hansen netted the insurance goal to finish off a satisfying win for the Skippers (19-2-0). “I tried to just hit it as far in front of me as I could, so I could just run to it,” she said.
Sophomore Madie Donovan had given Cohasset a 1-0 lead in the first half.
