Facing elimination for the fourth time in a week and trailing Clarke by two runs before swinging a bat in the deciding Game 3 of Nassau’s Class A Baseball Championship Series, Calhoun staged one of his most big rounds of the season at the perfect time.

The top-seeded Colts exploded for nine runs on seven hits late in the second and never looked back on the way to winning their first county title since 2012 with a 12-6 win at Farmingdale State College. . Senior Alec Edwards scored two runs in the inning and drove in two, seniors Brian Chin and Andrew Schneir both had two hits, and junior Charlie Imhof scored twice and drove in a run.

“We’re a brotherhood and we always support each other,” said junior Matt Kalfas, who raked home plate in Calhoun’s two final wins with a 6-7 record. “This team has a lot of character,” a- he added. “We were behind in both heats, the semi-finals and the finals, and we stayed confident and focused.”

Junior PJ Kakalos pitched the final 2 1/3 innings in relief to senior starter Dan Bondi for Calhoun (24-3), who meets Rocky Point for the Long Island Class A Championship Saturday at 4 p.m. at St. Joseph’s College by Patchogue.

“It’s an incredible achievement,” Colts coach Art Canestro said. “Nassau Class A is the most difficult group there is and we had to fight after a game in the semi-finals [against Division] and against Clarke.

“We are a team capable of making a big run at any time,” he added. “We showed again today that our roster isn’t just a few guys, it’s all nine.”

Fourth-seeded Clarke, who made a comeback in ages against MacArthur in Game 2 of the semis with a five-point rally late in the seventh to keep his season alive, finished 22-7-1.

The Rams won the Finals opener, 3-1, last Saturday on a two-run brace from junior JJ Palumbo in the sixth. Chin and Clarke, sophomore Nick Berasti, both kicked the lights out. Berasti allowed just two hits and also scored the tying run on Nick Giardino’s single.

Calhoun won Game 2 of Memorial Day, 6-2, on three-run rallies high in the fifth and seventh innings. As the Colts clung to a one-run lead entering the seventh, Schneir provided the insurance with a three-run homer off the foul post in left field.

Schneir also had a sacrifice ball in the fifth as Calhoun broke a scoreless tie. Sophomore leadoff Joey Goodman and junior Ryan Pucella also had RBIs. Kalfas tripled, doubled and singles.

Calhoun senior Shane Linett threw well in the bottom of the fifth and lifted for Kakalos with the bases loaded. The Rams went through two runs, both charged to Linett, but left a pair of runners on base.

Clarke came out batting in Game 3 and had two runs to lead the first in RBI singles by second Giancarlo Rengifo and junior Zaim Deljanin.

But the Rams’ lead quickly evaporated.

It was still 2-0 with two out and Imhof on second base late in the second when the onslaught began. Edwards hit Imhof at home, then scored the tying run on junior Jordon Babbo’s single. Clarke’s first of five errors kept the inning alive, as did Kalfas beating an infield grounder to charge the bases. Chin then fouled several tough pitches before giving the nod in midfield for a 4-2 lead.

“We’re the heart kids,” said Chin, who Canestro named the starting pitcher to face Rocky Point.
