TAMPA — Giancarlo Stanton could not be happier in his short time as a Yankee.

“It’s so cool, man, such a cool experience and I haven’t even experienced it yet,’’ Stanton told The Post with a big smile, putting his Yankees experience in perspective.

That was before Stanton crushed his first home run as a Yankee, a two-run shot to the right of the batters eye in center field at Steinbrenner Field on Saturday off a Matt Harvey fifth-inning fastball in the 10-3 win over the Mets.

Stanton’s 59 home runs last year are what people know. But it is the unique approach Stanton continues to perfect that makes him such a dangerous hitter as he pairs up with Aaron Judge to form

The Bronx Bashers.

Here is an inside look at Stanton’s mindset.

“I was a flawed hitter, for a few years in the league I was pretty much just a guy swinging at a ball,’’ Stanton, 28, told me. “I had a lot of battles with myself where I had to learn in the big leagues.

“I may have some unconventional things that I do but you are not supposed to do things to look good for other people, you do it to get your own feel and what works for you,’’ the 6-foot-6 Stanton said, noting his closed stance.

“Everyone’s opinion on how you look and how it should be done, they are not the ones in the box. It’s a lot of trial and error, mostly error to kind of help me to know what I need. You have the positives as a guideline.

“With the power and everything I can do things wrong and get away with it and people will say that it’s right, which is what took me a little longer to realize what I need to do.

“A lot of film on where is my contact point? Where are my feet? All of that, a lot of times no matter if I started open, straight up, a little closed my best striking position was closed.’’

The process began in 2012.

“I started straight and would come closed, that’s when I noticed it and I enjoyed that rhythm of it,’’ Stanton said. “In 2014, I said my legs are the slowest part of my body so let’s eliminate that.

“Now I don’t have the most power from this position but I have the most barrel accuracy, which in a sense is more power,’’ he explained. “I’m definitely more powerful straight up but I’m less consistent. I will take consistency and barrel accuracy.

“I want to let the ball get as deep as possible and put the best barrel onto the ball. It reminds my muscle memory how fast my hands are and how much time I have to get to a 98 mile an hour fastball.

“You can take 50 mph BP and hit a homer every time,’’ Stanton explained. “That ain’t going to help me when they are throwing 98 and a 93 mph slider.’’

Judge called Stanton’s approach and work “meticulous.’’

“You have to be precise with the things you know and you did something wrong, but it was right,’’ Stanton said. “You’ve got to know what you’re looking for and what you felt because the way you feel in the box could be different than the way it looks when you look at it. You have to remember the thought process. That’s what I can do, I can know exactly what I was thinking when I look back at a video whether it was a year ago or two years ago.’’

That is a gift.

“I figured all this out on my own,’’ Stanton said. “I can hit a ball in the cage and people will say, ‘Great job,’ but seriously, ‘Great job,’ that’s not the best.

“You can always be better.’’

Which brings us to Yankee Stadium, and some of the other AL East parks like Camden Yards that should make Stanton an even more productive hitter.

“There weren’t any cheap homers in Miami,’’ Stanton said. “That was a battle too not to just make everything a big swing. Now we can let the ball travel with the short porches. It should allow me to stay within myself.’’

Do that and baseballs will fly, and Stanton’s Yankees experience will be off the charts.
