FORT MYERS, Fla. — Hey, Pablo Sandoval, you only need to look a couple of lockers down to know what being in shape means.

Pablo, meet Chris Young.

When it comes to body types, they’re polar opposites.

Young, Boston’s free agent pickup, is as fit as any Red Sox player has been in years. Sandoval is as out of shape as any Red Sox player in years. As he walked into camp Sunday morning Sandoval’s appearance was rather shocking.

Who knows the reasons one player feels so compelled to be in great shape and another doesn’t.

Sandoval, who will get a paycheck that amounts to more than $45,000 a day in 2016, has normally had the ability to overcome his body.

Young has always had to fight for his place on a team and felt conditioning was vital to his success as a defender and as an offensive contributor, which he has been throughout a career that has taken him through Arizona, Oakland, both New York teams, and now with the Red Sox.

Young, 32, had a very good season with the Yankees in 2015, serving as the fourth outfielder. He batted .252 with a .320 on base percentage, a .453 slugging percentage in 356 plate appearances and 140 games.

Manager John Farrell said the righthanded-hitting Young is “gonna get every lefthanded starter we see.’’ Farrell didn’t specify how he felt Young would be utilized, but the only lefthanded-hitting outfielder is Jackie Bradley Jr., who happened to hit .306 with a .918 OPS against lefties and .221 with a .791 OPS against righthanders.

“In fairness to Chris, there has to be some action against righthanded pitching to keep timing,’’ Farrell said. “It’s clear his strength is hitting against lefthanded pitching. We also have to consider what’s the best combination of a lineup on that given day.’’

The Yankees wanted him back, but couldn’t fit him into the budget they had appropriated for a fourth outfielder. So they traded for a less experienced but better defensive choice in Minnesota’s Aaron Hicks, while the Red Sox signed Young to a two-year, $13 million deal. Young said he harbors no bad feelings toward the Yankees.

“No, not really,’’ Young said. “I don’t get surprised by anything. Every team has the right to make moves that they think make them better. No hard feelings there at all. I had a great opportunity there and had a lot of fun.’’

Coming to Boston was a sign of how much the Red Sox respected his play.

“I’m excited,’’ Young said. “Ever since I started talking to Boston in the offseason I decided it was an opportunity I’d be really interested in. It’s a great spot. My role has been the same for the last couple of years, and I need to be ready for whatever. I may come in as the fourth outfielder, but I need to be ready for anything.’’

Four times in his seven years in Arizona, he hit 20 or more homers, including 32 in 2007. He played regularly with Arizona until his role diminished starting in 2012, his final season with the Diamondbacks.

Young became a platoon outfielder after that, first with the A’s in 2013, the Mets in 2014, and the Yankees in 2014 and 2015.

Young hit 14 homers for the Yankees last season, but that number could easily go up as Young is a dead-pull hitter and likes the Green Monster. He has developed into a player who can sit for a while and then play without losing timing at the plate.

“I don’t think you ever get mentally adjusted to it,’’ Young said of the platoon role. “You keep the competitive mind-set and help the team every day. And you want to do that as regularly as possible. If you’re producing you want the opportunity to go out there and produce. Just go out and play hard, and whatever happens, happens.’’

Young’s best position is probably left field. He was a very good center fielder earlier in his career, but the corners are his new strength. He thinks the Red Sox have great talent with the young outfielders who he said he watched closely when he was a Yankee.

“Their athleticism is something special,’’ Young said.

Among the things Young is looking forward to is his second “farewell’’ tour for a teammate. He experienced the Derek Jeter farewell tour last season and found it “energizing’’ and special. He said David Ortiz, playing his final season in 2016, is one of the most beloved players in baseball and a mentor to many.

“You can see how players just gravitate toward him. He’s like a big brother to them. It’s going to be a fun season and the players are really going to give him a special sendoff,’’ Young said.

Young said he had other chances to go to teams who had starting situations for him, but he really likes the competitiveness of the AL East. He’s also enjoyed his time in the Northeast and loved the passion he experienced being a Yankee. He said he’ll have no issues crossing sides of the Red Sox-Yankees rivalry, even though he loved his time in the Bronx.

Young feels the Red Sox did a lot of good things to vault them back into the pennant race.

“I saw the [Craig] Kimbrel trade and then as I was in the process of signing I had an inkling about DP [David Price]’’ he said. “And [Carson] Smith, I faced him last year. All those moves to the bullpen are important and starting pitching is important. Hopefully I can add something to the lineup.’’

On this date, he at least adds a player to the roster who is in tip-top shape, a far cry from the guy a couple of lockers down from him.

If you need motivation, Pablo, look at Young. Watch, look, learn how it’s done.
