NEW CANAAN — In front of a crowd so loud that it shook the inside of the New Canaan YMCA swimming pool Darien was able to outlast New Canaan 102-82 to stay undefeated.

“We always have a really competitive meet against New Canaan,” Darien (5-0) coach Marj Trifone said. “I always look forward to some very fast times here because they seem to always rise to the occasion and I thought we had some really good challenges.”

Darien’s pure depth proved to be the unraveling of New Canaan, as despite an impressive performance the Rams couldn’t quite overtake their rivals.

New Canaan faced the same issue against Greenwich on Tuesday, notching fast times but being outlasted by the Cardinals; something coach David Fine said must improve to stay with teams at the top of the FCIAC.

“The last few years I’ve had a lot of depth on the team, so that’s helped us,” Trifone said. “But this was the first meet that we got challenged in that way; Monday, we swim against Greenwich; they’re very deep and very good, so that’ll show how much depth we actually have.”

New Canaan took the 100-meter breaststroke behind Libby O’Hare, who made up one-quarter of the 400 freestyle relay team that also won, alongside of Meghan Egan and Katie and Lizzy Calwell.

“We did very well,” Fine said. “It’s a tough combo to swim Greenwich Tuesday and come back and swim today, and the girls rose to the occasion. They swam a lot better today than Tuesday, you can’t ask for more when you go faster. That’s all we can control.”

The Rams (3-2) mixed things up a little Thursday, and Fine was happy with the results. Freshman Audrey Adl led New Canaan to its first win, and junior Gwenyth Thalacker swam well in her first 50 freestyle while also leading the 400 freestyle relay.

For Darien, the quartet of Rachel Stobbie, Isabel Blaze, Phoebe Slaughter and Lauren Rutledge took the 200 freestyle relay, and Catherine Gorey took the longest, and maybe the toughest, event, the 500 freestyle.

After the meet, Trifone, who is married to Darien football coach Rob Trifone, said she had a little to do with the crowd noise.

“My twins (Bobby and Christian) are on the (football) team,” Trifone said. “So I told them you better come support the swim team, and they did, and brought others.”
