It was a better-than-average night for three off-duty NYPD cops — who saved a man’s life while competing in a bowling league on Staten Island.

The officers were easing into their first game on league night at Rab’s Country Lanes in South Beach around 7 p.m. Sunday when one of the cops, Giovanni Cucuzza, 28, noticed a fellow bowler falling to his knees.

Cucuzza and his NYPD teammates then sprang into action.

Officer John Desiderio, 34, began CPR, while fellow Finest Joseph Glorioso kept the unidentified man’s airways open.

“You go into autopilot,’’ Glorioso said Tuesday at a press conference at police headquarters in Manhattan.

Meanwhile, Cucuzza bolted to the reception desk where, because of the team’s weekly visits to Country Lanes for practice, he knew there would be a defibrillator kit.

Desiderio continued CPR after Cucuzza brought the downed bowler’s pulse back with a shock with the defibrillator.

The victim was taken to Staten Island University Hospital, where he is now in stable condition.

“To know that he gets to spend more time with his family, I’m grateful for that,” Desiderio said.

Cucuzza added, “I definitely felt like I needed to rise up and serve, because this is exactly what I signed to do, to help.’’

The officers go by the name “Blues on Strike” when bowling.

They resumed their competition at the alley after the ailing man had been taken away by ambulance — and won.

“It was probably the best game of my life,” Desiderio said.
