Sacred Heart Greenwich’s lacrosse team was determined to jump out to a fast start in its home-opener against School of the Holy Child and set the tone of the game quickly.

Mission accomplished, in a big way.

Host Sacred Heart scored the game’s first eight goals, tallied 13 times in the first half and rolled to a resounding 19-4 win over Holy Child on Wednesday.

Senior midfielder/co-captain Franny O’Brien helped pace the Tigers, recording a hat trick with two assists in the winning effort.

“I’m really proud of how we played today, it was definitely a team effort,” O’Brien said. “We came out really strong, really hard and I’m really proud of how we performed today. It was our first home game, so we wanted to come out strong, start the season strong and I think we did that.”

Junior attack Kelly Haggerty registered two goals and five assists, junior attack Karina Sethi tallied three goals and one assist and Mackenzie Coleman, also a junior attack, had a hat trick for the victors.

The first half began with the Tigers posting five shots on goal, all of which were saved by Holy Child’s goalie. The home team then found its mark when sophomore midfielder/attack Payton Sfreddo converted a shot with 21:01 remaining in the opening half, making it 1-0.

“Their goalie had several saves right off the bat, she had five saves to start the game,” Sacred Heart co-head coach Sharon Robinson said. “Our girls did a good job of generating possession and getting those shots. Then we got into our groove and we started finishing our shots. We are hoping for a nice balanced attack and I thin we had about 11 players score.”

Sfreddo, sophomore midfielder Maggie Baciagalupo and freshman attack Charley Baciagalupo added two goals apiece for Sacred Heart, which entered halftime with a commanding 13-1 advantage. Sophomore midfielder Kaitlin Robinson and senior attack Abby Barnett had one goal apiece for the Tigers, who controlled possession throughout.

“I think it was great, we came out with a lot of energy and ready to go,” Sfreddo said. “I think everyone here is really excited to play and be a part of this team and we showed that by coming out this strong in our first home game.”

O’Brien scored off a pass from Sethi, Robinson tallied off a catch-and-shoot and Charley Bacigalupo found the back of the net with a shot, putting the Tigers on top, 4-0, at the 19:39 mark of the first half.

A nice spin move resulted in another tally by O’Brien, who added another goal in transition, putting Holy Child in a 6-0 hole with 16:31 to go in the opening half. Charley Bacigalupo scored in transition and Sfreddo tallied off the draw for the Tigers, who seized the momentum from the start.

“We have a lot of potential that we’re working on every day in practice,” Kaitlin Robinson said. “Throughout the season we’re going to make a lot of progress. To work together and always give 110 percent.”

Laura O’Connor, a junior, and Isabella Berkey shared the goalkeeping duties, with O’Connor making two first-half saves in the victory. When Sacred Heart’s defenders were tested, they provided effective play.

“A lot of our defense started on the offensive end, so our rides were looking good,” Sacred Heart senior defender/co-captain Lauren Giuriceo said. “We caused a lot of turnovers in midfield, so we were able to capitalize on that.”

Senior attack Abby Barnett and sophomore Wowie Walker added one assist apiece for Sacred Heart, which hosts Rye (N.Y.) High School on Monday at 4 p.m.

“I think it’s a great team, because we have a lot of depth all the way from our freshmen to our seniors,” Sacred Heart senior attack Dylan Drury said. ‘We’re a really strong team and everyone plays really mature no matter what their age.”

Drury appreciates the time she’s spent on the Tigers’ successful squad.

“The four years on the team have flown by,” Drury said. “Every year we’ve had really awesome leadership with captains in coaches. We’ve had different a lot of different coaches every year, but it’s made us grown even more as a team.”

Wednesday’s game marked one of the couple of games the Tigers will play against FAA teams. They are no longer in the FAA, after winning the FAA Tournament title three consecutive seasons.

“It’s something new for us, being out of the FAA and playing new teams,” Sfreddo said. “With all the tough competition coming up, it pushes us to work harder in practice and have high intensity and coming out ready to face our next hard opponent.”

“We looked really good, we were creating a lot of opportunities and we were finishing on a lot of those opportunities,” O’Brien added.
