As Director of Pro Scouting, I lead a talented group of evaluators as we break down future stars. You can find me at random California League games throughout the season!
The Marlins are no longer having pitchers call pitches, and this has caused a stir. However, this goes to show that the Marlins are trying out new things and striving to be at the cutting edge of what is happening in the sport of baseball. The Marlins system is headlined by one of the game's premier left-handed pitching prospects, Thomas White, who is right on the doorsteps of the majors. The Marlins have quite a few talents close to the majors, such as Joe Mack and Robby Snelling. The Marlins are known for their pitching development, but their hitting development looks to be slowly but surely catching up. The Marlins invested heavily in hitters in their 2025 draft class, as they were able to bring aboard Aiva Arquette, Brandon Compton, and Max Williams into the fold. The Marlins are in a good spot at the major league level, as long as you don't watch Agustin Ramirez catch and you believe in the Kyle Stowers breakout. For the first time in a while, the Marlins might be a bit frisky, and a large part of that will be with prospects on this list coming up and playing meaningful roles.
About Our Top 20 Lists
Prospects Live, led by its evaluating team & Director of Scouting Rhys White, is proud to begin rolling out its annual offseason system reports. The team combines industry feedback, our live looks, film, and available data to compile each org. We believe this effort has enabled us to present you, the reader, with our best possible view of the prospects in the organization.
We have constructed this list using the Overall Future Potential (OFP) scale. There is no perfect equation for ranking prospects or assigning value to them, but we believe this method is the best possible approach. Every prospect on this list has been graded based on the tried and true 20-80 scouting scale. An 80 is the highest tool and OFP grade on the scale, reserved for MVP-caliber players or tools. Conversely, a 20 is reserved for non-prospects (NPs). A 50 OFP falls in the middle, indicating our evaluators deem this player a future average major league player. Below the 50 OFP tier are the 45s and 40s, comprising a large majority of players on each list. These are specific-role players, such as platoon hitters, utility players, or low-leverage relievers. Above the 50 OFP tier are the 55s and 60s. A 55 represents a future above-average player, and a 60 OFP designation is reserved for future All-Star caliber players.
In addition to the tool grades and OFP, we will also include a 'Risk' associated with each prospect. We use this to better communicate to you, the reader, whether a grade is more aggressive or conservative in nature. The evaluation team has worked hard to apply both the grades and risk components to better illustrate how each individual prospect stacks up in their respective system and in the baseball ecosystem.
Thomas White is one of the best left-handed pitching prospects in the entire sport, and he is on the doorsteps of the major leagues. Thomas White looks the part, having the prototypical starter's frame; he stands tall and has good weight. White’s delivery isn't the most fluid, as he tends to be upright during the follow-through of his delivery. The arm slot is unconventional as he almost gets that invisible look from his high three-quarters arm-slot paired with him being upright. Everything plays well out of the hand for Thomas White. White plays around with a four-pitch mix that all play off one another. The fastball is a comfortable mid-90s offering, averaging around 95 mph with about 16 inches of induced vertical break from that high arm-slot. The fastball sets everything up, as he uses it just about 50% of the time. The best secondary pitch, and maybe the highlight of the entire arsenal, is a changeup with ample tumble and fade. It averages about 12 inches of arm-side fade and is a real weapon against right-handed batters when spotted low and away. He plays around with two shapes of the slider: a harder sweeper with some bend and a more vertical breaking slider that he mixes in more to left-handed batters. His fastball-sweeper-changeup to right-handed batters is a good trio that is hard for right-handed batters to do anything with when White's command is working. The lefty approach needs a touch of work as he scraps the changeup for the slider. The biggest red flag for White has been strike-throwing and command. The command and control tend to come and go during the outing. This leads to bouts of ineffectiveness as well as inefficient innings that lead to him getting pulled early. White has potential front-of-the-rotation stuff, but the command at times makes everything play down. If he can get the command to even a 45, he has a chance to be one of the better left-handed starters in the sport. - Rhys White
