Miami Marlins Top 57 Prospects

Sam Navarro-Imagn Images

Below is an analysis of the prospects in the farm system of the Miami Marlins. Scouting reports were compiled with information provided by industry sources as well as my own observations. This is the fifth year we’re delineating between two anticipated relief roles, the abbreviations for which you’ll see in the “position” column below: MIRP for multi-inning relief pitchers, and SIRP for single-inning relief pitchers. The ETAs listed generally correspond to the year a player has to be added to the 40-man roster to avoid being made eligible for the Rule 5 draft. Manual adjustments are made where they seem appropriate, but we use that as a rule of thumb.

A quick overview of what FV (Future Value) means can be found here. A much deeper overview can be found here.

All of the ranked prospects below also appear on The Board, a resource the site offers featuring sortable scouting information for every organization. It has more details (and updated TrackMan data from various sources) than this article and integrates every team’s list so readers can compare prospects across farm systems. It can be found here.

Eric Longenhagen Prospects Chat: 6/13/25

12:06
Eric A Longenhagen: Good morning from dangerously hot Tempe, where I am coffee’ing at the kitchen island getting ready to work on Red Sox and Twins lists while prepping for the Combine.

12:07
Eric A Longenhagen: FOr those who missed it, please go read the Rangers list:

Eric A Longenhagen: And the Mariners list: Seattle Mariners Top 29 Prospects | FanGraphs Baseball

12:08
Ken: Has Jack Perkins’ performance so far in Vegas moved the needle for you at all in terms of how you view his ability to remain a starting pitcher?

12:11
Eric A Longenhagen: Yes. Ran into him last week as I was working on Mariners and he carved. Physicality looks like he’ll be able to handle it even if he isn’t the most efficient strike thrower. Let’s keep in mind, though, that he’s looked like this (sitting 95-96 t98, plus slider, strikes) for like five weeks, six weeks? It’s not as strong a look as if he’d been doing it since April.

Eric Longenhagen Prospects Chat: 6/6/25

12:02
Eric A Longenhagen: Howdy from Tempe, where it seems like it’s time to pay the price for living here yet again. First day of the Combine is currently forecast for 115 degrees. I might be brief today to go finish up the Rangers list. Padres list went up this week, go check that out.

12:02
Matt: Any ETAs for the 2025 draft BOARD update and mock draft(s)?

12:02
Eric A Longenhagen: Post Combine most likely

12:02
Takao: This is more a “organizational question” than a prospect question, but Baseball America has ranked the Reds minor league hitting development the worst in baseball 3 of the past 4 years (with a bottom 5 showing in year 4). In your opinion, does that ranking accurately reflect the overall system outside of the obvious names (Collier, Stewart, etc.)? Worth noting, Reds fan here and I’d tend to agree that our hitting dev has been atrocious since roughly 2021.

12:05
Eric A Longenhagen: I think they’ve accidentally ended up with a lot of chase-prone hitters, or hitters with a consistently exploitable weakness that would make it hard for them to have sustained success. Lots of guys with “inside out” styles of contact there, too. Would I say their hitting dev is bad though? I think that’s as much of a black box as anything in dev, tough to say from the outside.

12:05
Nervous Flyball Pitcher: I’ve seen reporting that FCL Orioles’ Joshua Liranzo’s max EV is up to 106.8 mph, but I don’t really have context for that. Is that number good/average/bad for an 18-year-old? Do you know if he has good EV90 or contact data so far?

Eric Longenhagen Prospects Chat: 5/30/25

11:57
Eric A Longenhagen: Good noon from the Cardinals backfields in Florida. I’m getting started a few minutes early so I can focus on the game a little sooner, as we’re about to get underway. Plus, there are already a ton of questions in the queue.

11:58
Eric A Longenhagen: I’m hotspotting, so apologies if things are spotty, internet-wise.

11:58
Eric A Longenhagen: In any case, thans for being here.

11:59
Guest: Any advice on how to get into/improve scouting abilities? Any resources that have been imperative in your learning?

11:59
Eric A Longenhagen: I would read Jason Parks’ chapters in the second edition of Extra Innings, I would read Dollar Sign on the Muscle, Future Value, and go see bad baseball at your local colleges.

12:00
Dallas: What’s the balance between actual production vs. K rates? I look at guys like Esmerlyn Valdez and Konnor Griffin, each have performed admirably this season and have up arrows, however both of their K rates are relatively high. Is the production legit or is the K rates red flags for long term success?
