WINCHESTER — In a battle of unbeatens at Knowlton Stadium, it was smooth sailing all the way for the Hingham boys lacrosse team.

Aedan Milligan scored just 13 seconds into the game and the Harbormen never looked back, clinching back-to-back Coaches Cup championships with a decisive 11-3 win over host Winchester.

Rocco Egan continued his dominance in the faceoff circle, winning 12 of 16 to help the Harbormen (5-0) maintain a huge advantage in time of possession and keep the Red and Black (6-1) at arms’ length throughout the game.

“We know that’s what he brings to the table,” Hingham coach John Todd said. “That’s the luxury of having a kid like Rocco.

“I’m just happy that he’s healthy. Last year was a mess for him, health wise, and he’s come back with a vengeance.”

Hingham didn’t let its senior faceoff specialist’s efforts go to waste. Michael Garrity set the pace with four goals and Owen Packard added two on an afternoon where seven different Harbormen found the back of the net.

When the Red and Black did have possession, they were consistently stifled by goalkeeper Nate Hoffman and a stout Hingham defense.

“Having a great goalie in Nate is another huge luxury,” Todd said. “You have kids taking great shots and he’s making great saves. It takes the air out of their offense.”

Milligan’s goal jump-started the offensive attack, and Hingham eventually raced out to a 6-1 lead a few minutes into the second. Gianni Deprimeo scored midway through the quarter to cut the Winchester deficit to 6-2, but the Harbormen responded with a flurry of offense to put the game out of reach for good.

Just 46 seconds after Diprimeo’s goal, Colin Lasch scored off a heads-up feed from Cam McKenna, and Patty Browne added another goal for Hingham 17 seconds later after Egan got the ball back at the face off circle yet again.

It was 9-2 by halftime and the Harbormen played the second half on cruise control to repeat as champions of the early-season Coaches Cup.

Despite a hot start to the season, Todd is focused on the long haul and hopes the tournament win will serve as a springboard for more success this year.

“We know that it’s a journey. It’s the whole season. You can’t get too down or too high,” Todd said. “(It’s) working on the small stuff. We did so many great small things today.”
