FALMOUTH — St. Dominic scored three power-play goals in the first period Saturday night and went on to a 9-2 victory against Greely in a girls’ hockey opener at Family Ice Center.

Kristina Cornelio (three goals) opened the scoring on a five-on-three advantage with 5:35 left in the first period on a pass from Emma Theriault for the Saints.

On the ensuing faceoff, the puck bounced straight to Theriault, who skated down the slot and scored on a wrist shot to make it 2-0.

St. Dom’s tacked on its third power-play goal of the period with 2:43 remaining, when Theriault connected with Isabelle Frenette, who finished for a three-goal lead.

“This was a tough first test and against this team, that basically made it impossible,” said Greely Coach Nate Guerin. “You’re going to struggle to keep up with them five-on-five, so if it’s five-on-four or five-on three, you have almost no chance. We spent a lot of energy killing penalties, so by the time we were back to five-on-five our girls were pretty beat.”

The Saints opened the second period still on a power play following a Greely boarding penalty late in the first, and notched their fourth power-play goal just over a minute in. Bugsy Hammerton scored from Avery Lutraykowski and Frenette.

Three minutes later, Hammerton made 5-0, scoring off a pass from Lutraykowski. Cornelio was also credited with an assist.

Cornelio then scored with 2:06 left from Lutraykowski and Frenette.

Greely scored with 13:13 remaining when Courtney Sullivan used impressive stickhandling to maneuver around the last line of the Saints defense. Her wrist shot found the top right corner.

St. Dom’s added a goal with just over 11 minutes to play when a Frenette slap shot found its way over the blocker of goalie Nica Todd, who turned away 38 shots, including 15 in the second period.

“Unbelievable effort,” said Guerin. “She was our best player tonight, even if the scoreboard didn’t necessarily show it. She made a lot of quality saves against tough chances.

“Even when we were down 4-0, with the way she was playing, we felt like if we could get the next one we’d be right back in it. Going back in the (penalty) box took the wind out of our sails more than once.”

Cornelio tacked on a score with just over five minutes to play for the Saints, and Sullivan notched a breakaway goal for the Rangers less than a minute later.

Hammerton completed a hat trick with just under a minute to play, scoring on Lutraykowski’s fourth assist.

NEW ENGLAND CROSS COUNTRY

Seniors Abby Hamilton of Yarmouth High and Katherine Leggat-Barr of Greely placed 20th and 25th, respectively, at the Foot Locker Northeast regional cross country championship race Saturday at Van Cortlandt Park in New York.

Among the boys, Yarmouth junior Luke Laverdiere placed 38th. The top 10 finishers in each race earned trips to San Diego for the national championships.

Hamilton finished in 18:51 with Leggat-Barr six seconds back. Emily Carty, a Fryeburg Academy junior, placed 60th in 20:03 among a field of 92.

Laverdiere said he was among the top six or seven through two miles of the 3.1-mile race before fading. “At the two-mile mark everyone kind of surged,” he said. “There was a big downhill and I couldn’t respond. I’m kind of bummed but I think I ran all right.”

Laverdiere finished in 16:35. Henry Jaques of Freeport placed 54th among 139 boys in 16:50.
