The Marlins drafted J.T. Realmuto in the Third Round in 2010, and after four years in the minors, the Catcher made it to the main roster, playing 11 Games in 2014.  The Marlins knew that Realmuto was the Catcher moving forward, and he took over behind the plate in 2015.

Realmuto struggled as a rookie, with an OBP under .300, though his arm defensively was an asset.  He was much better in 2016, batting .303 and hitting at least .277 the next two years.  Realmuto's power numbers grew, belting 17 in 2017 with 21 in 2018.  He went to his first All-Star Game in 2018, and was also a Silver Slugger, and to date, it was the best of his career.  

Since this was the Marlins, you know what happened next.

As typical with Miami, they traded Realmuto away when they decided he no longer fit their budget, and his play elevated in Philadelphia, matching the higher salary he made as a Phillie.  Realmuto had 555 Hits with Philadelphia and batted .279.

From the Dominican Republic, Marcell Ozuna was signed in 2008, and five years later debuted for the Miami Marlins.

Ozuna became a fixture in Rightfield as a sophomore, peppering 23 Home Runs in 2014, a number he duplicated in 2016, which was his first All-Star season.  Ozuna followed that with a breakout campaign, blasting 37 Home Runs with 123 RBIs with a .312 Batting Average.  In addition to obtaining his second All-Star invitation, he won his first Gold Glove and Silver Slugger.  

As typical with the Marlins, Ozuna was traded before he could be priced out, with the Cardinals being his landing place. With Miami, Ozuna batted .277 with 96 Home Runs.

Cliff Floyd began his baseball career with the Montreal Expos, a team he played four years before being traded to the Florida Marlins in 1997.

Floyd played mostly off the bench in his first year in Florida, but he did help them win their first World Series Championship.  He became a starter in Leftfield in 1998, smacking 22 Home Runs, a total he matched again in 2000 when he batted an even .300.  Floyd had his best year in a Marlins uniform in 2001, going to the All-Star Game and hitting 31 Home Runs, 103 RBIs with a .317 Batting Average.   Floyd had come into his own, but he was traded in July the following year, returning to the Expos.

With the Marlins, Floyd batted .294 with 110 Home Runs.

Charles Johnson was an original in the Florida Marlin organization, taken very late in the First Round of the very first Amateur Draft that the Marlins participated in.

Johnson appeared in four Games in 1994, and the defensive genius became a starter for the Marlins soon after.  He quickly became known for what he could do with his glove and how he understood his hurlers. Johnson was named an All-Star in 1997 and was a member of Florida's first World Series Championship Team.  

After the World Series win, Johnson was one of the many Marlins who was traded, with his destination, the Dodgers.  Johnson returned to Florida as a Free Agent in 2001 and was an All-Star again.  He left for Colorado in 2003, ending his playing career with the Marlins for good.

Johnson had 467 Hits for Florida and a Defensive bWAR of 8.6, which is a franchise record.
