The Miami Marlins added some arms to the bullpen and had some issues with health as well unfortunately. The bullpen will consist of A.J. Puk (LHP), Dylan Floro (RHP), Tanner Scott (LHP), Matt Barnes (RHP), Huascar Brazoban (RHP), Tommy Nance (RHP), JT Chargois (RHP), Andrew Nardi (LHP) and Nic Enright (RHP). It's possible that some of these relievers won't be on the Opening Day roster, but let's look at these guys and see how the whole group looks at the moment.
The Miami Marlins bullpen looks solid.
Dylan Floro is very underrated, coming off of a 3.02 ERA/3.13 FIP with 8.0 K/9 and 2.5 BB/9 in 56 games and 53.2 innings pitched. I don't know why he's constantly overlooked, but he's a solid arm to have , considering he had a 2.81 ERA/2.81 FIP in 68 games and 64.0 innings pitched just last season.
New acquisition A.J. Puk delivered a 3.12 ERA/3.68 FIP with 10.3 K/9 and 3.1 BB/9 in 62 games and 66.1 innings pitched for the Oakland Athletics in 2022. He could end up as The Fish's closer when all is said and done. Tanner Scott has a great strikeout ability (12.9 K/9 in 2022 and 12.3 K/9 career), but has a career 4.61 ERA/3.91 FIP. He had a 4.31 ERA/3.67 FIP in 67 games and 62.2 innings pitched. Scott is volatile with high upside, but also a high downside (6.6 BB/9 in 2022 and 5.8 BB/9 career).
Another new bullpen acquisition is Matt Barnes. Similarly to Scott, Barnes has a high strikeout rate (11.6 K/9 career) and high walk rate (4.2 BB/9 career). He had a 4.31 ERA/3.87 FIP in 44 games and 39.2 innings pitched in 2022. Like Scott, there's high upside and high downside with him. Tommy Nance interestingly fits the same profile as Barnes and Scott, he had 11.7 K/9 and 4.3 BB/9 in 2022 along with a 4.33 ERA/3.71 FIP in 35 games and 43.2 innings pitched in 2023.
Nic Enright has not pitched in the Majors at all and has a career 2.80 ERA with 12.8 K/9 and 2.2 BB/9. Huascar Brazoban is a late-bloomer, having pitched his first season in the Majors last season at 32 years old. He delivered a 3.09 ERA/3.99 FIP with 11.3 K/9 and 5.9 BB/9. You may have noticed a trend by now, high strikeout pitchers with high walk rates. JT Chargois had a 2.42 ERA/4.28 FIP with 6.9 K/9 and 2.0 BB/9 for the Tampa Bay Rays in 2022. He has a career 3.54 ERA/3.87 FIP with 9.1 K/9 and 3.4 BB/9 in 162 games and 152.2 innings pitched. In Chargois's case we have a promising reliever with problematic advanced metrics.
The Miami Marlins bullpen has high upside but also high downside. If Tanner Scott, Matt Barnes and Huascar Brazoban struggle with walks that severely hurts the group. Of course if they control their walks, they can be pretty dominant relievers. I'm of course specifically focusing on Scott and Barnes. Overall, it's a solid bullpen that has the potential to be pretty dominant.
