Pitching a fit

Red Sox fan Bill de Blasio, who’s let more than a few balls roll between his legs, must still be sore about the 1986 World Series. That’s the only sane explanation for why a mayor grappling with a city in crisis is wasting time and energy trying to scuttle the $2.4 billion sale of the Mets to Steve Cohen by using, or rather, misusing, a provision of the lease on the public land on which sits Citi Field. It lets the city bar those convicted of a felony or “a crime involving moral turpitude” or anyone who’s an organized crime figure or reputed to be.

Cohen is none of those; he has never been charged or convicted of anything. But he is a billionaire hedge funder whose former firm pleaded guilty to securities and wire fraud, thus making him a juicy target for class warrior de Blasio.

Cohen has the dough to spend big on the Mets and just maybe make them contenders, which is why we hope the Wilpon family’s sale to him is unanimously approved today by Major League Baseball’s owners.

If the mayor is really that interested in what is happening at Willets Point, there’s a better way for him to throw his weight around: He should refuse to bypass the city’s land-use approval process on the foolish multi-seat ride AirTrain the Port Authority wants at LaGuardia.

Building this wasteful $2 billion thing requires relocating Citi Field parking spaces from under the No. 7 tracks to vacant parcels. That necessitates a zoning change. Proponents would have de Blasio issue a mayoral zoning override. Huh? There’s nothing in any law about zoning overrides.

Of course, taking aim at the AirTrain would require de Blasio facing off against AirTrain superfan Gov. Cuomo, a far tougher foe than Steve Cohen.
