After the sides were done scrapping Friday night following No. 11 Medfield’s 14-7 victory over No. 7 Dover-Sherborn in lacrosse, Warriors co-head coach John Isaf settled his players down and said two words: ‘‘Message sent.’’

The Warriors had been held to a season-low five goals while getting served their first loss of the season the last time these teams met in April. And a year ago, D-S had won its first Tri-Valley League title in school history. Medfield wasn’t going to let it happen again, and earned a share of the TVL with the victory at Medfield.

‘‘This feels amazing,’’ said Medfield senior attack Calvin Given, who notched a hat trick. ‘‘We were really focused on coming out and showing them we played a terrible game [the first time]. And we didn’t just want to beat them by a few goals. We wanted to step on the gas when we had it.”

Although the game looked like a wrestling match at times, the Warriors believe they were able to get into their opponents’ heads and run free.

Medfield’s midfield scooped up almost of the groundballs and worked seamlessly with the attacking unit to find clean looks on goal, while the Raiders appeared out of synch from the opening whistle.

Here was Medfield (14-3), playing one of its best games of the season (‘‘I hope we didn’t just peak,’’ co-head coach Mike Douglas said), while D-S (15-4) played one of its worst. D-S coach Brian McLaughlin said he’s never seen his squad make that many errant passes and sloppy turnovers.

The difference-maker might’ve been Warriors attackman Conor Roddy.

Roddy was forced to watch from the sideline with a concussion the first time these squads met, but on Friday he required constant attention from Raiders sophomore Zach Abrosino.

Roddy was electric off the ball and just as good with it, dishing out three gift-wrapped assists.

‘‘It was terrible watching from the sidelines the last time,’’ he said. ‘‘And everyone on this team wanted it really badly. This is probably the most intense game we’ve had in a while.’’

Warriors senior Chris Diana scored four goals and sophomore Matt Crowell added three.
