Aníbal Sánchez arrived in Florida as a central piece of the franchise-altering trade that sent Josh Beckett and Mike Lowell to Boston. A highly regarded arm from Venezuela, he was expected to join a new wave of young talent that could stabilize the rotation for the next generation.

In 2006, Sánchez demonstrated his raw ability by going 10-3 with a 2.83 ERA, but his crowning achievement came on September 6 against the Arizona Diamondbacks. He authored the first major league no-hitter in over two years, a specialized performance that snapped the longest drought in the sport's history at the time. This breakout season earned him a top-ten finish in the Rookie of the Year voting.

Between 2010 and 2011, Sánchez made a comeback after years of localized shoulder struggles. In 2010, he demonstrated full mastery of his repertoire, recording 13 wins and 157 strikeouts while pitching nearly 200 innings for the first time. In 2011, he continued his strong performance, finishing sixth in the league with 202 strikeouts and third in strikeouts per nine innings.

Sanchez was traded to Detroit during the 2012 season, and later in his career, he would win a World Series with Washington in 2019.  With the Marlins, he had a 44-45 record, a 3.75 ERA, and 676 strikeouts.

While still in the Minors, Ricky Nolasco arrived in Florida after a 2005 trade with the Cubs. A right-hander whose value lay in a tireless arm rather than flashy, top-of-the-rotation results, he rarely operated as a definitive ace but became a symbol of durability for a franchise often defined by rapid turnover.

In 2006, Nolasco demonstrated his readiness by winning 11 games, anchoring a young staff that famously featured four rookie starters with double-digit wins. After an injury-shortened 2007, he returned to the mound in 2008 with his most dominant statistical campaign, racking up 15 wins and a then-franchise record 186 strikeouts.

Between 2008 and 2012, he consistently won at least 10 games in five seasons. Despite giving up many hits and a high ERA, he was efficient by avoiding walks, ending with a 3.51 strikeout-to-walk ratio, one of the highest in franchise history.  During the 2013 season, he was traded to the Los Angeles Dodgers and departed as the franchise’s absolute leader in nearly every major longevity category, a legacy of service that eclipsed the records of more famous names like Dontrelle Willis.

Nolasco compiled an 81-72 record, a 4.44 ERA, and 1,001 strikeouts.

J.T. Realmuto was a third-round selection by the Marlins in 2010, an athletic former quarterback who transitioned from shortstop to catcher with surprising speed. After a brief 11-game look in 2014, he seized the starting job behind the plate in 2015.

The early days of his run were marked by a steep learning curve and a fierce commitment to defense. While his rookie season saw an on-base percentage stay under .300, Realmuto immediately turned heads with his pop time and mobility. He found his rhythm in 2016, posting a .303 average and proving that his athleticism was a massive asset on both sides of the ball.

Realmuto reached a career peak in Miami during 2018, a year in which he secured all major positional awards. He hit 21 home runs, was selected for his first All-Star game, and received a Silver Slugger. By that time, he had built a reputation as a versatile player who could hit for average, hit for power, and suppress the opposing team's running game. His 2018 season remains one of the best seasons ever by a catcher in team history, confirming the scouts’ belief that he was a future superstar during his minor league days.

The exit from Miami arrived in February 2019, as the Marlins moved their biggest remaining star to the Philadelphia Phillies in exchange for a package that included Sixto Sanchez and Jorge Alfaro.  With the Marlins, Realmuto had 555 hits, 59 home runs, and a .279 batting average.

Marcell Ozuna came to the Marlins in 2013 as a high-voltage talent from the Dominican Republic, a player whose raw power and "cannon" for an arm made him an immediate tactical asset. After signing as an international free agent in 2008, he steadily climbed the ranks to become the high-caliber center fielder the organization had been searching for.

After debuting promisingly in 2013, Ozuna showed strong batting in 2014, hitting 23 home runs with 85 RBIs. Following a slump, including a 1-for-36 stretch, the Marlins demoted him to Triple-A New Orleans in July. His agent, Scott Boras, accused the team of delaying his service time to manipulate arbitration eligibility. Ozuna called the 33-day demotion a "jail sentence," and although he returned in August, his relationship with the front office remained tense.

Despite last year's challenges, Ozuna demonstrated remarkable resilience in 2016. He rejoined the lineup as a key player and delivered an impressive first half, hitting .307 with 17 home runs before the All-Star break. This performance earned him his first All-Star nod, where he was chosen as the starting center fielder for the National League. Although his effectiveness waned somewhat in the second half, he concluded the season with 23 home runs and 76 RBIs.

Ozuna then had his best season (2017), finishing the year with a .312 average, 37 home runs, and 124 RBIs. This high-stakes production earned him his second consecutive All-Star nod, along with his first Silver Slugger.  As par for the course, Ozuna was traded for four players (one of whom was Sandy Alcantara) to St. Louis.  With Miami, Ozuna had 683 hits, 96 home runs, 376 RBIs, and a .277 batting average.
