In an earlier entry, we mentioned that Luis Castillo is one of three Marlins to have won both of the Marlins’ World Series titles, but only one of the three was a starter in both.  That man is Jeff Conine.

Conine would become an original Marlin, taken in the Expansion Draft from Kansas City after appearing in 37 Games for the Royals.  In 1993, Conine demonstrated his high-frequency reliability by playing in all 162 games, finishing third in the Rookie of the Year voting after a standout 4-for-4 debut on Opening Day. He quickly became a professional mainstay, earning back-to-back All-Star selections in 1994 and 1995, including a high-stakes moment where he was named the 1995 All-Star Game MVP after a go-ahead pinch-hit home run. 

Between 1995 and 1996, COnine had consecutive seasons with at least 25 home runs and set a career-high 105 RBIs in 1995. He demonstrated specialized versatility by alternating between first base and left field to accommodate the team’s evolving rosters of high-caliber players. During the 1997 World Series, although his regular-season performance declined, he remained a valuable technical asset in the clubhouse. He played a crucial role in the franchise's first championship, offering the veteran presence necessary to guide the team through a seven-game series against Cleveland.  Ironically, he would be part of the Marlins’ first fire sale and was shipped back to Kansas City after their championship.

Conine's time in South Florida wasn't over, as he made a notable comeback in late 2003. He was acquired from the Orioles on the last day of August and became a key player the Marlins needed for their second championship run. Demonstrating a unique resilience, he quickly returned to left field, enabling a young Miguel Cabrera to move to third base. His exceptional performance in the 2003 postseason was impressive, batting .458 in the NLCS and .333 in the World Series against the Yankees. Conine stayed with the Marlins until he signed with the Orioles after the 2005 season.

With the Marlins, Conine had 1,005 Hits, 120 Home Runs with a Slash Line of .290/.358/.455.

The trade that brought Gary Sheffield from San Diego in June 1993 was a high-voltage acquisition during the franchise's inaugural season, signaling the Marlins were ready to compete with the established giants.

Despite early injuries, he demonstrated a unique talent for controlling the strike zone, blending power with focus. By the mid-90s, he was a reliable force for the Marlins, anchoring the lineup with unmatched intensity.  In 1996, Sheffield had one of his best seasons in baseball, belting 42 home runs with 120 RBIs while leading the National League in On-Base Percentage (.465), OPS (1.090), and OPS+ (189). He earned a Silver Slugger and finished sixth in the MVP voting.

The year after, Sheffield was not as productive, but it was arguably the most important campaign of his long career.  He was the power man for the Marlins' historic World Series run, hitting a home run in every postseason series—the NLDS, NLCS, and the Fall Classic.  It was the quickest run from infancy to championship for a franchise, but the season after would show baseball fans what the Marlins’ identity really was.

Following the championship, the organization entered a tactical rebuild, and Sheffield was traded to the Los Angeles Dodgers in May 1998 as part of a blockbuster deal for Mike Piazza, who would himself be traded days later to the New York Mets.  A member of the 500 home run club, Sheffield hit 122 of them as a Marlin.  He also had an OPS for the team.

Mike Lowell arrived in South Florida in early 1999 as a trade acquisition from the Yankees, a local product who had briefly tasted the Bronx spotlight before being moved to his hometown team. While he joined a club still finding its post-1997 identity, he quickly established himself as a professional mainstay at the hot corner.

After securing the starting job in 1999, Lowell demonstrated a high-frequency ability to drive in runs, recording his first 20-home-run season in 2000, and earned three consecutive All-Star selections between 2002 and 2004.  The meat of his All-Star sandwich (2003) was Lowell’s best season in the Majors.  He posted career-highs in home runs (32), RBIs (105), and slugging percentage (.530). He earned a Silver Slugger Award and finished 11th in the MVP voting, providing the high-caliber offensive engine that pushed Florida toward a Wild Card berth. Despite a localized setback late in the year with a broken hand, he returned to provide a veteran presence that aided the Marlins in capturing their second World Series title.

Lowell was also excellent defensively. Between 1999 and 2005, he was a fixture at third base, consistently hovering near the top of the defensive leaderboards. While his offensive volume dipped in 2005, he showed the organization he was still a high-caliber asset by winning his first career Gold Glove Award.

As is almost always the case with veterans, Lowell was traded to the Boston Red Sox alongside Josh Beckett.  With the Marlins, Lowell had 965 hits, 143 home runs, and a career .272 batting average.

When Jose Fernandez was 15, he and his mother successfully defected from Cuba (on their fourth attempt) and settled in Florida.  A baseball prodigy, Fernandez would become a first-round pick in the Amateur Draft in 2011, and two years later, he was a Miami Marlin.

At only 20 years old, Fernández showcased a unique talent for overpowering top Major League hitters. His debut in 2013 remains one of the most impressive in history. That season, he went 12-6 with a 2.19 ERA, led the league in hits allowed per nine innings (5.8), and earned the National League Rookie of the Year Award. He was also third in Cy Young Award voting, establishing himself as a potential top pitcher of his generation. However, fate had other plans.

Fernandez, the youngest Opening Day Pitcher since Dwight Gooden, had his second MLB season derailed in May by a torn UCL. He underwent Tommy John Surgery and made a late July 2015 comeback. Between his recovery and his record-breaking 2016 season, Fernandez was in top form. He earned his second All-Star nod and struck out a career-high 253 batters in just 182.1 innings. During this period, he was a consistent force on the mound, giving fans a compelling reason to attend every five-day game. His blend of a specialized "slurve" and a powerful fastball made each start feel like a potential no-hitter.

Sadly, the end for Fernandez far too soon.  He died in a boating accident on September 25, 2016, at the age of 24, ending what could have been one of been a spectacular career.  As it stood, Fernandez left us with what might have been.

Fernández compiled a 38-17 record, a 2.58 ERA, and 589 strikeouts.
