VIERA, Fla. — The World According to Bryce: No limits.

NL MVP Bryce Harper, in saying Monday that the Mets are the team to beat in the NL East, noted he will be with the Nationals — at least for the next three years.

But baseball’s best player can be a free agent after the 2018 season. Continue to save all your pinstripe pennies, Yankees. Every one of them.

Asked directly by The Post about possibly being a Yankee in the free-agent future, the Washington outfielder said: “I have the ‘W’ on my chest for the next three years. I’m very humbled to put the ‘W’ on my chest each and every day. I love the nation’s capital. I love DC. It gives me chills thinking about it right now. It’s such a monumental town, and I look forward to playing there every single day for the next three years. That’s what’s on my mind right now.’’

In three years, though, sounds like that free-agent door is wide open for the Yankees.

Harper is only 23. These three years will fly by.

“Everybody is talking about a sum of money, but you can’t put limit on players, you can’t put limit on what they do,’’ Harper said as he sat in the first-base dugout at Space Coast Stadium, one day after visiting the Daytona 500. “Everybody says, ‘The sky’s the limit, the sky’s the limit,’ and we’ve been on the moon. Let it play out. I’ve got three years to play. I’ve got three years to do everything I can to play this game.’’

He will continue to shoot for the moon.

Harper hit .330 in 2015 while leading the majors in home runs (42), runs (118), on-base percentage (.460), slugging percentage (.649), OPS (1.109) and OPS-plus (195). He is a new version of Mickey Mantle, his dad’s hero, and has more home runs than Mantle had through the age of 22 (97 to 84).

Harper will be a $400 million player. At least.

As for the 2016 season, Harper said: “The team to beat are the Mets. That’s what it is right now. They kicked the crap out of our division last year. Hopefully we can come in this year and do what we can.

“You don’t want to give them too much credit. But they’re incredible. They have great young guys who are going to be tough for years to come. Hopefully we come in here this year and do what we can do and knock them off, knock everyone else off. Play our game.’’

Harper also said all is good regarding the Jonathan Papelbon choking incident last September. The closer recently apologized for his role in the dugout scuffle.

“That is something that just happens,’’ Harper said. “It was squashed that day. We’re going to go about it the right way as a team this year and come together. That’s all that matters. All I want to do is win.’’

Harper insisted he is not a vocal leader, but a leader by example.

“Let him be Bryce, that should be enough,” new Nationals manager Dusty Baker said. “I expect him to continue to grow as a player and a man, how many people at 23 years old have been where Bryce has been?

“The great ones have great vision, they see things other people don’t see and they have tremendous drive, never satisfied. I once asked Sadaharu Oh how he stayed motivated as an eight-time MVP [in Japan]. He said he wanted the ninth.’’

Harper appears to be on the same page with Baker.

“Dusty is a player’s manager for sure and he understands the game,’’ Harper said. “He understands the grind, the mentality. There’s nothing better than having a manager who understands the game of baseball.

“All I care about is winning. I don’t care about MVPs or accolades. I’m very humbled by the award I got last year. I just want to stay healthy and play the game hard. I was thrilled to be MVP. I can’t thank the writers enough, but whatever, last year is in the past. The 42 homers, the .330 average, I’m not worried about that.

“We have such great young talent here and I’m excited about [ex-Met Daniel] Murphy hitting home runs off lefties, hopefully.

“I feel great coming into spring, my body feels great, the swing feels awesome, I made no changes with that,’’ Harper said. “The sky is the limit. I just want to stay healthy.’’

Superman has three more years with that “W” on his chest to battle the Mets in the NL East. Save all your pinstripe pennies, Yankees.
