FAIRFIELD — They stand, potentially, three wins away from the promised land. Three wins from fulfilling a goal that started last summer after Fairfield American’s dream was dashed in Bristol at the New England Regional instead of Williamsport, Pa., and the Little League World Series.

Last summer, Fairfield American needed just one win to punch their golden ticket to Williamsport, but Rhode Island took the ticket and made the dream a nightmare in the championship game. This time, however, Fairfield American is hoping that it will write a different ending — a winning ending — and make the World Series for the third time since 2010.

“I know they’re excited. The coaches are excited; the families are excited. I’m nervous. Absolutely. If I’m not nervous, I don’t think I’m into it,” Fairfield American manager Mike Ransazzo said this week during a practice at Mill Hill School. “These boys are prepared, they’re ready. Excited? You bet.”

Over the course of nine district games, three sectional games and three state championship games, Fairfield American has found a way to win each time, standing at 15-0 heading into Monday’s New England Regional opener against the winner of Maine and Vermont (who play today) at 1 p.m. at the Giamatti Little League complex in Bristol (ESPN3). They’ve won with pitching. They’ve won with defense. They’ve won with power. They’ve blown teams out and won heart-stopping nail-biters.

“You would think that we’re battle-tested and I’d say we’re prepared,” Randazzo said. “We know these games are going to be tight. Five of the last six games we’ve played have been close. It’s going to come down to pitchers getting ahead in the count, hitting their spots, and when the ball’s hit, because it will be hit, guys making the plays, particularly late in the game. You need to get outs.”

You also need to score runs, and that’s one thing Fairfield American has excelled at over the summer. In those 15 games, they have scored 174 runs — an 11.6 runs-per-game average — hitting 53 home runs, 13 of those coming off the bat of Michael Iannozza.

“We’re solid from top to bottom and our subs can put the bat on the ball and make a play for the team and help us out,” said Iannozza, who’s hitting .617. “Everyone is handling their role well and getting good at-bats and everyone’s producing runs for the team.”

And that has been the key to Fairfield’s success. Everyone on the roster, from starter to sub, has contributed during this undefeated run. Owen Kalagher had a game-winning two-run double in the bottom of the sixth to beat Newington 5-4; Christian Smith went 3-for-3 with a home run and three RBIs in a 22-9 win over North Branford; Anthony Pollack had a home run in the 8-6 win over Wallingford; Sean O’Neil had a two-run triple in the win over Ridgefield; Griffin Dodder had a double and two RBIs versus North Branford, just to name a few.

“Everyone can hit the ball, up and down the lineup, whether they’re starting or not. I think a lot of it has to do with confidence,” pitcher Ethan Righter said. “It’s fun to see everyone contributing and knowing that not just the top of the lineup has to hit the ball every game.”

“Let’s be honest, you can’t get this far without 14 people contributing when you have a 14-person team,” Randazzo said. “We practice a lot of different situations. Everyone gets the same amount of reps. We have guys playing different positions and we need to make sure that they’re getting enough reps at those positions. We put everyone in situations in practice, so when they have to deal with them during games, they know what to do. That’s a big part of it, whether that’s the defensive side or the offensive side.”

And it’s a credit to players like Anthony Falletta and Andrew Cutler, O’Neil, Smith and Dodder, who not only know but accept their roles and are ready to deliver at a moment’s notice.

“From Day 1 in practice, that’s what we talked about. We told the boys and we reinforced it over the summer that it’s the next man up, you have to be ready because everyone is going to play,” Randazzo said. “You need to be focused and you need to be ready and come to practice and work and prepare yourself for when you’re called on.”

And you can bet that all 14 players on the roster will be tested over the course of the regional tournament.

“Those three state tournament games, we really had to battle,” Randazzo said. “Now, heading into the regionals, we can draw off those experiences. I can remind them that we did this, we did that, we’ve been through this before.”
