PORT ST. LUCIE — During infield drills in Mets pre-camp Friday, David Wright was at third base while Daniel Murphy was at second.

In between, over at shortstop, was young Matt Reynolds.

Don’t be surprised if the Mets take the field at some point in 2015 with Reynolds at short. Reynolds continues to make the transition back to shortstop, where he played his entire baseball life before moving to third base at Arkansas.

Wilmer Flores is penciled in at short for the Mets with Ruben Tejada backing him up, but you can be sure Reynolds, 24, is in the middle of the Mets’ plans as he continues to improve at the position.

“I feel really comfortable at short,’’ said Reynolds, who hit an impressive .343 in 2014 at Double-A Binghamton and Triple-A Las Vegas, collecting 164 hits over 126 games.

That will get you noticed and get you moving up the line.

“I think I can definitely stay there and hopefully I can make a contribution to the team this year,’’ Reynolds said. “I feel like with a little more seasoning and experience, I can definitely help this team.’’

There is a sense about Reynolds that he belongs, that he is a good fit for a major league team.

Talk to anyone around the Mets about Reynolds and the first thing mentioned is the laser focus. He is locked in from the moment he walks onto the field.

Here’s one reason why: His dad was an Army ranger.

“My dad was an Army Ranger and my mom was a nurse, that’s how they met,’’ Reynolds said.

Reynolds grew up in Tulsa, Okla. After the Army, Gary Reynolds became a consultant who designed roofs for large buildings such as high schools and hospitals.

“My dad was always hard on me when I was younger,’’ Matt Reynolds said. “When I was young, I didn’t understand it. Now that I’m older and a little bit smarter, now I understand that without those experiences I wouldn’t be the person that I am today.

“It was nice because he works from home and he was able to work with me a lot,’’ Reynolds added. “He always taught me, ‘If you are going to do it, you might as well do it right, so why screw around and get worse when you have an opportunity to get better?’ ”

There you have that tremendous focus again.

Reynolds is friends with Flores and is rooting for him.

“I love working around Flo, he’s a great guy. He’s funny and he can really swing the bat,’’ Reynolds said of Flores. “Flo is a friend of mine and I want to see him succeed. Things will play itself out.’’

Spring training will be interesting.

From a distance, Reynolds looks a bit like Wright, especially when he is wearing No. 5 like last spring training, when he came up to play with the big club in games on about 10 different occasions.

Some fans thought Reynolds was Wright and clamored for his autograph.

“I’d say, ‘Sorry I’m not David. I’m Matt.’ I feel like some people got mad because I was wearing No. 5,’’ he said with a smile.

Wright has helped Reynolds along.

“To have a guy of that status to be so down to earth and talk to, I guess, little people like us who are still in the minor leagues, it just shows his character, what type of guy he is, what kind of leader he is for the team,’’ Reynolds said of Wright. “That helps everyone because it helps you relax and just be yourself.’’

After the minor league season, Reynolds played shortstop in the Arizona Fall League and impressed the scouts.

“I’m just trying to become more consistent with everything,’’ said Reynolds, a second-round pick in 2012. He attended the Barwis workout camp, run by trainer Mike Barwis, in Florida for the second straight offseason, as did Flores.

“It’s the best money I spent in my entire life,’’ Reynolds said of the camp. “It’s an investment in your career.’’

Reynolds’ career is quickly moving forward.
