PORT ST. LUCIE — Strategically speaking, Mickey Callaway will lean firmly on the side of analytics in managing the Mets, but he also plans to bring a human touch.

It’s an approach Callaway developed in five seasons sitting alongside a future Hall of Fame manager, Terry Francona, while serving as pitching coach in an Indians organization deep into statistical analysis.

Callaway recently sat with The Post and outlined his managerial philosophy on several topics, as he continues through spring training and prepares for his first Opening Day as a manager.

— Callaway embraces the shift, but won’t force it on his pitchers.

“We are going to explain to the pitchers that they are going to know ahead of time if we are going to shift a batter,” Callaway said. “The reason we are going to be shifting is for 50 different reasons: How this guy hits off every right-hander, how he hits off guys like you, so it’s not just he hits the ball over there and we are going to shift him. We are going to dig deeper.”

When Callaway was Indians pitching coach, Corey Kluber made it clear he disliked the shift and exceptions were made. Callaway will solicit the same kind of input from the Mets pitchers.

“We are going to tell them, ‘You have to tell us beforehand if you don’t want the shift,’ ” Callaway said. “You can’t let a bleeder go through and then go, ‘What are we doing shifting?’ But we are going to do some shifting.”

— Bunting is not taboo, but Callaway will try to avoid it.

“Our pitchers can hit a little bit, so the numbers say one thing,” Callaway said. “But first and second, nobody out, our pitcher is going to be bunting if that makes sense. But every time there’s a man on first and nobody out we might let them swing, because they can swing a little bit.”

Callaway is more likely to ask a starting pitcher to bunt deeper into a game.

“Let’s say [Jacob] deGrom has gone six innings and he’s dealing,” Callaway said.

“His spot comes up and there is a man on first, I am going to have him bunt. Get him off his feet. Get the bunt down, jog to first, get back in the dugout and go back out and pitch the seventh.

“I don’t want him hitting a double. If we are winning 3-1 and he’s throwing a gem, I am not worried about him driving in runs. I want him to get the guy over, get him rest and go pitch the seventh and save one of our bullpen arms. It will look inconsistent, but there will be a reason behind it.”

— Starting pitchers are pretty much finished at 100 pitches.

“It’s a case-by-case basis: What has he done his last couple of outings?” Callaway said. “We have to take that into account. Another thing we really have to take into account this season is the amount of innings guys have thrown in the past. To expect them to go out and throw 110 pitches, 110, 110, all of a sudden their workload is going to go way up. One hundred is alarming, and then we will start, ‘We’ve got to get somebody going.’ But I think guys can handle, 108, 106. You won’t really see anybody throw over 115 pitches, that is just silly.”

Even if the pitcher is throwing a no-hitter?

“We are not going to throw a 130-pitch no-hitter,” Callaway said. “They are just out. They can hate me.”

— Three straight days of work is possible for relievers.

“I won’t shy away from that if they are feeling OK,” Callaway said. “Three would be the max. I know [Joe] Girardi never did three, that was the rule. I remember [Andrew] Miller coming over and saying they had that steadfast rule about it. If [Jeurys] Familia gets an out one day and then the next day clean inning, 16 pitches, he is definitely going to be available.”

— The Mets aren’t constructed to steal bases, so Callaway will pick his spots.

“It has to be a very successful rate for us to start stealing bags,” Callaway said. “It’s got to be 85, 90 percent, but I think if we get aggressive leads and we prepare on guys that don’t have great times, catchers that can’t throw, I think if we have all those factors lined up, we are going to take some shots at it with guys that can run.”

“If you are putting one of your better hitters batting second, it makes sense to bat the pitcher eighth, so you have another guy in front of that guy when he comes around,” Callaway said. “Between the eighth and ninth spot if that pitcher is getting a third at-bat, he is dealing anyway so we are in a good spot. If not, the pitcher is going to get two at-bats and get out.”

— Even with a potentially short bench, Callaway isn’t a fan of using pitchers as pinch hitters.

“There might be a time or two if we know he is feeling OK and we have a 2¹/₂ innings heads-up where we can get him loose,” Callaway said. “We will never go, ‘Hey, go pinch hit,’ without getting him loose. Now we might do that just to get a bunt over if it made sense to do it at the time, but we’ll have to see. And pitchers will never pinch run. That’s silly, in my mind.”
