Customers waited in line at Lord & Taylor on Fifth Avenue Thursday night for a chance to pose with an All-Star righty with signature flowing hair.

There was talk Jacob deGrom would get it cut this offseason. But he delivered a breaking news flash:

“It’s probably going to stay now,” deGrom told Newsday, declining to elaborate.

The Mets provided two breaking news flashes Wednesday, acquiring second baseman Neil Walker from Pittsburgh and agreeing to a two-year deal with shortstop Asdrubal Cabrera.

“It’s exciting,” deGrom said. “ . . . I’m looking forward to getting to know those guys in spring training and having them play behind me.”

The price tag for Walker was Jon Niese. It also meant Daniel Murphy won’t be back.

“Those are both great guys that I enjoyed playing with,” deGrom said. “I think everybody knows how this game works, so it’s all part of it.”

So can the Mets return to the World Series?

“I definitely think so,” deGrom said. “We’ve got a good rotation. I think it all starts with good pitching.”
