Jordan McLune burst over right tackle and into the secondary. He was gone, and so was Farmingdale.

The senior halfback scored his third touchdown of the first half on a 76-yard run and sent Farmingdale into halftime with a 28-point lead on its way to a 56-0 win over Massapequa in a Nassau I semifinal football game Thursday night at Hofstra’s Shuart Stadium.

If McLune’s first half seemed special, he topped it with an even better second half, which featured four more touchdowns — punctuated by a 96-yard run.

McLune finished with 390 yards on 16 carries and tied a Nassau playoff record with seven touchdowns. He has rushed for 1,527 yards and 32 touchdowns this season.

Top-seeded Farmingdale (10-0) will play Freeport for the Nassau I title at 7 p.m. next Thursday at Hofstra.

Farmingdale, which forced six turnovers and recorded five sacks, turned two of Massapequa’s three first-half turnovers into quick touchdowns and used big plays on both sides of the ball to dominate the half.

“We were definitely opportunistic,” coach Buddy Krumenacker said. “We had a big lead at the half and we let them know not to assume anything. We wanted them to come out and continue to fight the fight.”

And indeed they did. On Massapequa’s first possession of the third quarter, a big hit by linebacker Corey Bull forced a fumble at the Dalers’ 1-yard line and denied the Chiefs the chance to score. Defensive back Joe Quinn recovered and returned the ball to the Dalers’ 32.

After two runs by McLune netted 11 yards, Tom Donovan hit Anthony Burriesci for 32 yards to the Chiefs’ 25. McLune then went the rest of the way for his fourth TD and a 35-0 lead with 6:35 left in the third quarter.

“We were excellent up front on the line,” McLune said. “I wasn’t getting hit on some runs.”

He added scoring runs of 6, 48 and 96 yards. Two of those scores came after an interception by Mike Manetta and Quinn’s fumble recovery. Farmingdale scored 28 points after turnovers.

“We played tight defense and forced a lot of turnovers,” said Quinn, who had two interceptions and a fumble recovery. “After Corey’s hit at the goal line, I saw the ball pop loose and my eyes just widened. There was no whistle, so I picked it up and started running.”

Massapequa (7-3) struggled against the swarming Dalers defense from the start. On the Chiefs’ opening drive, defensive tackle Nick Milianta recovered a fumble at the Dalers’ 39. Four plays later, McLune ran 19 yards for a touchdown and Briant DeFelice added the extra-point kick to make it 7-0 with 9:51 left in the first quarter.

DeFelice, who kicked a winning 34-yard field goal in Farmingdale’s 45-42 regular-season victory over Massapequa, again was golden. He converted all eight extra points.

“We played a complete game,” Krumenacker said.

Farmingdale scored two touchdowns in the final 2:02 of the first half to forge the huge lead. Donovan hit a streaking Antonio Smikle Jr. in stride for an 87-yard touchdown and a 21-0 lead with 2:02 left. Quinn’s interception at the Farmingdale 24-yard line set up McLune’s 76-yard scoring dash with 1:01 left in the half.
