The baseball career of Pete Alonso has been short, but it has been potent.

Alonso won the National League Rookie of the Year in 2019, while leading the NL in Home Runs (53) and Extra Base Hits (85) while going to the All-Star Game and earning All-MLB 1 honors.  It was a great start, but it also exposed that the First Baseman was prone to striking out often, was slow, and was not a great defensive player, yet his power made Pitchers shiver.

Since that time, Alonso finished third in Home Runs in 2020 and 2021, and was second in 2022 year (40) in a year where he won his first RBI Title (131).  The power kept on gushing from Alonso's bat last year with 46 Home Runs and 118 RBIs, but his .217 Batting Average was his lowest to date.

The two-time Home Run Derby winner is one fo the top power hitters in Baseball and will rocket up this list if he stays a Met for years to come.  Alonso enters 2025 with 226 Home Runs, and will break 250 this year.

Sandy Alcantara is the perfect example of why you can’t judge a Pitcher solely on their record.

As of this writing, Alcantara has been with the Marlins for four years after being traded from St. Louis, where he played in only eight Games.  Alcantara mainly played in the Minors but became a permanent starter the year after.  It was bittersweet for Alcantara, who became Miami's best hurler, but due to a lack of run support, he led the NL in Losses (14).  He had a good 2020 (3-2 3.00 ERA) but again had a poor record (9-15) in 2021 though he had a nice ERA of 3.19.

Alcantara won the Cy Young in 2022, making him the first Marling to do so.  He also went to his second All-Star, and had a 14-9 Record with a 2.28 ERA and 0.998 WHIP.  He did not follow that with another Cy Young caliber year (7-12, 4.14 ERA, 151 SO), but he missed the entire 2024 Season recovering from Tommy John Suregery.

If he returns healthy and becomes one of the few players who stays in Miami for a long time, he could reach the top of this list.

Robb Nen played nine Games for the Texas Rangers before being traded to the Marlins in their expansion year.  

Nen was not very good the rest of the year, as his ERA was 7.01, but he got significantly better, and would be promoted to the team's closer during the following season.  In 1995, Nen had an abysmal 0-7 record, but had a respectable 3.29 ERA, with 23 Saves.  His best year in Florida came after, with 35 Saves and a 1.95 ERA, and though his ERA went back up over three in 1997, he equaled his 35 Saves from the year before.  The Marlins went to the postseason, and Nen had four Saves in the Playoffs, and the Marlins won it all, but that was the end for him in Florida.

Following the World Series win, Nen was one of the many players traded, with San Francisco being his destination.  He Saved 108 Games as a Marlin.

A.J. Ramos was a late round selection (21^st) in 2009, and the Texan Pitcher was a Miami Marlin for the first five years and change of his career.

Ramos was never a starter, and he began his MLB career in middle relief, which included a 7-0 season in 2014 where he had a 2.11 ERA over 68 Games.  He did so well that year that the Marlins promoted him to be their closer, and he shut the door with 32 Saves in 2015 and 40 Saves in 2016.  Ramos was especially good that year, going to the All-Star Game and posting career-highs in Saves.  

The Marlins did what they always did during the 2017 Season and traded him when his contact would eventually become due.  Ramos would finish 175 Games for Miami and Save 92.
