The division reports debuted last year. The goal of this article series is to provide a quick overview of all dynasty-relevant information from each division. Each team has multiple minor league levels, each containing plenty of impactful prospects which can feel impossible to keep up with. This article series, which will be updated once per month, will help dynasty managers stay up-to-date on performances, injuries, promotions, and more. New this season is the inclusion of tiers in the rankings. Next to their rank, each prospect is assigned a tier. The tier range is 1-5.
- Tier 1: A potential difference-making dynasty prospect. Somebody who would rank in the top-20ish prospects for dynasty baseball
- Tier 2: A still very good dynasty prospect who holds plenty of value. This prospect would typically rank in the 21-75 range
- Tier 3: A mid-tier prospect who could be valuable but has questions and concerns present in his profile ranking in the 76-150 range
- Tier 4: A prospect who is worth knowing, but is reserved for deeper leagues. This prospect would rank 151-250
- Tier 5: The rest of the prospects fall into Tier 5
The Marlins are going to need to hit on several of the prospects below if they want to get out of the cellar in the NL East. Agustin Ramirez is already with the Major League club, but they are going to need more than that. Deyvsion De Los Santos and Joe Mack are knocking on the door of the Major Leagues, but besides that, most of Miami’s top-end talent is in the lower level of the Minor Leagues. Several prospects filling up the back of this top ten list are off to slow starts, including Carter Johnson, Andres Valor, and Starlyn Caba. Keep reading for the latest on Miam’s farm system.
Notable Prospect Performances:
- With their second-round pick in 2024, the Marlins took a shot on a prep bat with big-time athletic upside in Carter Johnson. Unfortunately, Johnson’s professional career has not gotten off to a strong start. In Low-A, he is batting just .175 with one homer and six stolen bases. Johnson’s swing has looked too long at times, leaving him overmatched even against low-level pitching. His batted ball data has been underwhelming, and his hit tool has been especially concerning. Johnson’s professional career is still incredibly fresh, but after slashing .161/.259/.247 in May, he moves down to ninth on this list.
- Echedry Vargas was viewed by many to be the main piece going back to Miami in the trade, sending Jake Burger to Texas. While Burger has certainly had his struggles to start 2025, Vargas is looking less and less like an impactful prospect. Vargas’ aggressive approach has been exploited in High-A and the power/speed potential he showed off with Texas has seemingly disappeared. On the season as a whole, Vargas is batting just .171 with two home runs and four stolen bases. He owns a 33 wRC+ and is no longer considered to be a prospect worth rostering in dynasty formats. Notably, his two home runs did come in the past week which is hopefully a sign of things to come.
- Joe Mack’s numbers have slowed down since joining Triple-A. Mack is the biggest mover on this prospect ranking list thanks to an excellent start to the 2025 season. Last month’s article hit on his promotion from Double to Triple-A, and this month we can look at how he is performing. The reason for not moving Mack further up this list is his hit tool. Mack has always struggled with strikeouts in his professional career. Since joining Triple-A, his contact rate has dipped down to 70.2% while he continues to chase a high rate of pitches out of the strike zone. His batted ball data has also been underwhelming as he appears to fit more into the Isaac Paredes mold of pulling for power. This is not necessarily a bad thing, but it is fair to wonder how this will translate to playing his home games in Miami.
Notable Promotions and News:
- PJ Morlando is hurt yet again. Just last month, Morlando was noted in this section for having returned to game action, but he is already back on the IL after suffering a leg injury. The severity of the injury has not been disclosed. Injuries have become an unfortunate theme early in Morlando’s career. He has appeared in just nine professional games since being drafted 16th overall by Miami last season. Morlando has the raw skills and attributes to turn into a significant dynasty prospect, but there remain too many unknowns to push him into the top ten of a quietly deep Miami farm system.
- Deyvison De Los Santos suffered a quad strain during the game on May 16. He has not appeared in a game since. De Los Santos was up to five homers and four stolen bases through 40 games at Triple-A this season. Strikeouts continue to be a problem this season as his strikeout rate sits at 30.5%, which is the highest rate of his professional career. This, combined with his tendency to hit ground balls, makes it difficult to rely on his massive raw power ever resulting in fantasy relevance.
- Thomas White has been dealing with a finger injury. White missed a handful of starts nursing this injury, but returned to the mound last Friday. White continued to throw on the side throughout the injury and this is not expected to cause issues moving forward. Through seven starts, White has continued to strike batters out at a high rate this season. His 33.9% strikeout rate is the main reason he remains one of the game’s top pitching prospects. Developing more control and consistency over his plus stuff will be key to help him achieve his potential.
