Could the New York Mets have a potential problem with Matt Harvey?

There are already signs of him being high maintenance … signs he enjoys the trappings of New York too much … signs he doesn’t handle injuries well … signs of being too sensitive … signs he knows he’s good and isn’t afraid to let you know.

Harvey has never pitched a complete season and is 12-10 lifetime. While we’re not talking about the second coming of Tom Seaver, Harvey seems to be carrying himself with a sense of entitlement and a “you can’t touch me’’ aura.

The latest is his reported reluctance to want to undergo his rehab in Port St. Lucie, which the Mets prefer, and desire to work out in New York.

After Harvey threw for the first time Saturday, general manager Sandy Alderson backed off saying where the 24-year-old 2010 will rehab, but made clear his preference.

“As a general rule, our players rehab in Florida,’’ Alderson said Saturday. “But that’s not a decision we’re going to make or mandate [now]. When we get to the end of spring training we’ll see where he is, and I’m sure there will be discussion between now and then.’’

MattHarvey1For somebody with 36 career starts, why should there even be discussion? If Port St. Lucie was good enough for David Wright and Pedro Martinez to rehab, it should be good enough for Harvey.

In fairness, we haven’t heard Harvey’s reasoning for his preference of New York, which leads to speculation, with little of it showing him in a good light.

Making this more touchy is this could go before the Players Association, as the collective bargaining agreement mandates a player can refuse his rehab in a spring training locale during the season for longer than 20 days.

“The CBA imposes limitations. Yeah,’’ Alderson said. “But in the past, for the most part, our players have been here and it’s been a good situation.’’

We know New York is Harvey’s home, has superior Italian food and a better nightlife than Port St. Lucie.

But, what’s the purpose here?

New York’s nightlife makes one wonder, as Harvey clearly enjoys the perks of being a star – even though that might be a premature characterization of his professional status. Harvey likes the clubs and openly spoke about his drinking in a Men’s Journal magazine piece.

“I’m young, I’m single,’’ he was quoted as saying. “I want to be in the mix. … I have a 48-hour rule. No drinking two days before a start. But, those other days? Yes, I’m gonna go out.’’

The bottom line: If you’re 24 and a high-profile figure, you shouldn’t need a rule about drinking. If he finds it necessary to have a rule, he shouldn’t be drinking in the first place.

Everybody these days has a phone with a camera. Harvey has already been caught several times in incidents of public displays of affection with his former supermodel girlfriend, Anne V. at Rangers and Knicks games, where he is gifted the tickets. More trappings.

He’s now seeing another model, Ashley Haas, which has his comments of wanting to be like Derek Jeter resurface. Of course, It is doubtful Jeter would have ever posed nude.

“That guy is the model,’’ he said. “I mean, first off, let’s just look at the women he’s dated. Obviously, he goes out – he’s meeting these girls somewhere – but you never hear about it. That’s where I want to be.’’

New York’s nightlife has burned out dozens of athletes. Look what it did for Dwight Gooden and Darryl Strawberry. Imagine what Mickey Mantle would have been able to accomplish with a little less drinking and womanizing.

And, as for Jeter, he’s not the Teflon he’s made out to be. Stories of sending his conquests home with a gift basket of memorabilia and forcing house guests to surrender their cell phones don’t portray him in a flattering light. Mom must be so proud.

Shortly after the magazine piece came out, Harvey complained about being misquoted and taken out of context. A reporter for a magazine profile records everything, so it is doubtful the quotes were manufactured. Backing off his comments shows a lack of accountability.

Harvey also got into it with WFAN talk-show host Joe Beningo, ripping him on Twitter and then deleting the post.

When it comes to fighting with a radio personality or the media in general, it is futile as it comes off as petty and unprofessional, plus, he’ll never have the last word.

The media isn’t as easy to bully as was former teammate Jon Rauch, whom Harvey forced out of town after challenging the former Mets reliever to a fight because he didn’t appreciate the rookie hazing, which included getting doused with water while sleeping on the trainer’s table.

If Harvey had a problem he could have confronted Rauch in private rather than making for a very uncomfortable clubhouse scene. That’s something somebody with a professional grasp on things would have done. Instead, he came off as behaving like Jordany Valdespin.

That’s not the only thing Harvey hasn’t handled well. Twice he wasn’t immediately forthcoming in disclosing injuries to the training staff, and arguably it led to his elbow surgery.

I want the best for Harvey. I want him to have a long and brilliant career. However, he has a long way to go, on and off the field. He hasn’t always shown good judgment and a case can be made it cost him this season.

He needs to reign himself in off the field, and that includes not making a big deal about where he rehabs. If reflects poorly on him and makes one wonder if this isn’t about carousing the bars with Haas and watching the Rangers.

If he maintains this course, instead of a franchise pitcher, he could end being a high maintenance super nova.
