SACO — Freshmen Courtney Sullivan and Bridget Roberts powered Greely to a 4-2 girls’ hockey victory Saturday over Scarborough.

Sullivan’s goal with 10:22 remaining gave Greely a 3-1 lead. Roberts won a faceoff in the offensive zone back to Sara Johnson, who sent the puck to Sullivan, her defensive partner. Sullivan’s low shot from the right point sneaked between the pads of Scarborough goalie Lucca Sterrer.

Roberts scored twice, including the game’s first goal with 4:33 left in the first period.

Sullivan gained control of the puck in Greely’s defensive zone and raced up the ice, cutting from right to left. She gathered speed along the left boards and drove toward the net before passing to Roberts for a one-timer.

“I just had an opening and I could hear (Roberts) yelling, so I hit it to the front of the net and luckily she was able to put it in,” said Sullivan.

“She’s awesome, just dominant,” Greely Coach Nate Guerin said of Sullivan. “She’s a freshman, we’ve asked her to do everything: forward, defense, special teams, and you saw it tonight. She can take over when she needs to. She shows a lot of poise for a freshman and she has great hockey sense.”

The teams combined for only one penalty, committed by Scarborough (4-2), the reigning state champion. Greely (5-1) outshot the Red Storm 23-19.

“We just didn’t play Scarborough hockey. We gave them way too much space, way too much respect,” said Scarborough Coach Caitlin Cashman. “When you give that to a team like Greely, they will walk all over you. And that’s what they did.”

“It wasn’t our best game, but it was a great effort. The girls worked really hard,” said Guerin.

Greely maintained its 1-0 lead until the third period, when the game opened up. Just 36 seconds into the third, Sami Shoebottom tied the game with a rebound goal off Ellie Smith’s breakaway that was stopped by Greely goalie Nica Todd.

Just 1:33 after Shoebottom’s goal, Greely took the lead again on a goal by Victoria Lattanzi. Less than three minutes later, Sullivan delivered the winner.

“Obviously we don’t want to give up a goal to start the third period. But I think that the girls showed some good character to respond and finish,” said Guerin.

“We’re still looking for that 45-minute effort,” said Guerin.

Shoebottom scored again with 1:45 remaining to pull Scarborough within a goal, but Roberts scored with 22 seconds left to clinch the victory.

“(Greely) played really well, they played tough and hard. We played tentative,” said Cashman. “We were running around and not playing our game. Hopefully we learn from this and we come prepared and competitive every game.”

Maura Verrill, Emilee McGillicuddy, Maura Perry and Erin Molloy each had an assist for Greely.

Hannah Snyder and Megan Doak chipped in with an assist apiece for Scarborough.
