The relief corp for the Marlins features closers and a lot of them. Almost the entire list is comprised of closers or relief pitchers that turned into closers. Robb Nen headlines the list and Ugueth Urbina makes the cut even though he spend less than half a season with the Fish.
Robb Nen easily makes the cut because he was the closer when the Marlins captured their first title. He saved 108 games total for Florida and 35 in 1997 when they won the title. He had two saves against the Indians in the World Series that year. He went on to have several more successful seasons in San Francisco, but it was all started with the Marlins.
Antonio Alfonseca makes the list began his career with the Marlins in 1997 and ended it just before the next Marlins title—in 2001. He led the league in 2000 with 45 saves for the Marlins and finished with 102 saves for the team, overall.
Braden Looper may be a starter for the Brewers now, but he was a valuable reliever for Florida for five years. He saved 28 games in the title season of 2003 and had 46 overall in his stay in Florida. He was 2-0 pitching in relief in the World Series in 2003 and had a 3.69 ERA in his career in a Marlins uniform.
Armando Benitez makes the cut here even though his stay was brief in Florida. He played just the 2004 season in Miami, but what a season it was. In the All-Star year, he went 2-2 and led the league with 47 saves and also had a minuscule 1.29 ERA. It was arguably the best season of his solid career.
Ugueth Urbina came over to the Marlins in a deadline deal in 2003 to bolster the bullpen. He went 3-0 and saved six games down the stretch in helping the team win the wild card. He then matched that in the post-season by saving six games including two in the series against the Yankees. He barely used his locker in Miami, but he was a valuable addition to the team and rightfully earned a ring with the team.
Bryan Harvey. The last name may have many saying, "Who?" Harvey, a closer with the Angels for a few years, was the first true closer for the Marlins as he saved 45 games (with a 1.70 ERA) in the Marlins inaugural season (not bad). He fizzled out after that and only pitched in 13 games the rest of his career after the 45-save season, but that one season was a memorable one and perhaps his great season paved the way for other closers like Robb Nen.
There have been some nice arms in the pen in the brief history of the Marlins. Nen, Alfonseca, Urbina and others certainly won't be forgotten (or will) anytime soon.
