Marj Trifone guaranteed this would be a ‘mental’ meet.

But the veteran Darien High girls swimming and diving team coach didn’t say it would be flat out crazy.

Crazy it was though, for anyone within earshot of the raucous crowd at the Greenwich High School pool as the Blue Wave left, the once perennial champion hosts, capsized in its wake.

Pulling ahead late, the Wave won its first-ever Fairfield County Interscholastic Athletic Conference title meet tonight, outpacing the unseated defending champs-of-so-so-many-years, 374-366.

“I am very proud of my girls,” Trifone said. “We weren’t rested and we knew it was going to be a mental meet.”
