Wilton High boys swimming and diving head coach Todd Stevens knew his team would have some big holes to fill this season. He just didn’t figure there would be so many.

With three top swimmers having graduated and several expected returners opting not to swim this season, the Warriors will be very young and not as deep as hoped.

“Our depth is compromised more than I thought it would be. We have a young team,” said Stevens, whose squad opens the season today. “We have some good returning athletes, and we have some good freshmen coming in.”

Freshmen (six) and sophomores (six) make up 12 of the team’s 19 swimmers.

The Warriors are coming off a season that saw them finish at 5-5 and place sixth at the FCIAC championships, fourth at the Class L state championships, and 13th at the State Open.

The team graduated distance freestyler Will Suchy, a first-team all-FCIAC swimmer in the 200- and 500-yard freestyle; Harrison McCool, one of its top freestylers; and Kyle Wilson, the team’s top breaststroker who also swam the 200-yard individual medley.

The Warriors this year will be led by its three senior captains, Jack Lewis, Jackson Dill and Jason Cai.

Lewis, the team’s top returner, is one of the state’s top sprint freestylers. He placed seventh last year at the State Open in the 50 freestyle and was fourth at FCIACs and sixth at the Class L meet in the 100 freestyle. He also took ninth at FCIACs in the 100 backstroke.

Dill is another returning sprint freestyler, while Cai swam the breaststroke and 100 freestyle last season.

The four-member junior class has returners in James Steward (diving, butterfly), Dylan Flanagan (butterfly, breaststroke), Ryan Looney (backstroke, 200 IM) and Alex Li (200 IM, breaststroke).

The sophomore class returns Matt Schaller (500 free, 200 IM), Nate Snyder (backstroke, butterfly), Maxwell Downing (butterfly, backstroke), Jubair Huq (50 free, 100 free), Matthew Lamanna (butterfly, breaststroke) and Will Trentos (100 free, backstroke).

The team’s six freshman are Rory Hess, Kevin Hu, Alexander McDonnell, Nathaniel Newcomer, Michael Pien and Christopher Zhou.

“It’s a good group of kids. I’m excited about the freshmen,” said Stevens, who feels the Warriors’ best-case scenario is to finish fifth in the FCIAC and compile a 5-5 dual meet record. “We’ll be a middle-of-the-pack team.”

Stevens said Ridgefield, Greenwich and Staples should be the top three teams this season, with New Canaan, McMahon/Norwalk and Wilton vying for the next three spots.

The Warriors will hit the pool running, with three meets in four days to open the season, starting with today’s meet at McMahon/Norwalk.
