Success in baseball usually comes down to one thing: pitching.

Which is why expectations are high for the Wilton Little League 12U all-star team, which opens the District 1 tournament tonight at home.

“The key to winning, in my opinion, is defense and pitching, and we’re rich in both,” said team manager Mike Daversa, who has four or five solid pitchers he can put on the mound with confidence at any time.

“You go as far as your pitching takes you,” he said, adding that Wilton has an excellent defensive squad, as well. “Because we’re so solid defensively and pitching I do expect to go deep in the tournament. I don’t expect to be three and done.”

Wilton’s first game, tonight at the Wilton Y, is against Stamford American at 7. The team plays at Darien on Friday at 5:45 and finishes pool play on Sunday with a game at Ridgefield at noon. The top three teams in each pool will advance to the double-elimination playoff round.

Daversa, who is assisted by coaches Mike Sherrick, John Fischetti and Chris Tournas, said Wilton’s depth is a plus going into the district tournament.

The pitching staff features five solid hurlers in Justin Lewis, Cole Silvia, Michael Fischetti, Max Jarvie and Nicholas Tournas.

Behind the plate, Jarvie and Jackson Duncan will share catching duties.

The first base rotation features Lewis, Duncan and Nick Forgione, while at second base the team will have Jason Sherrick and Adam Daversa.

Cole Silvia will play shortstop along with Sherrick, while third base will be manned by Tournas, Jarvae and Colin Randol.

In the outfield, Wilton will have Daversa, Fischetti, Forgione, Jackson Carbonier, Gavin Lowne and Charlie Caporrino.

Daversa said that Silvia, Fischetti, Jarvie and Duncan will make up the “meat of the order” offensively, but that all the players can produce at the plate.

“All 13 kids can hit. We go 13 deep,” he said. “It’s a really strong team, deep in pitching. The kids are excited because we’ve got a lot of potential.”
