Below is our list of the top-100 prospects in baseball. The scouting summaries were compiled with information provided by available data, industry sources, as well as from our own observations.

Note that prospects are ranked by number but also lie within tiers demarcated by their Future Value grades. The FV grade is more important than the ordinal rankings. For example, the gap between prospect No. 5 on this list, Victor Robles, and prospect No. 35, Sean Murphy, is 30 spots, and there’s a substantial difference in talent there. The gap between Travis Swaggerty (No. 56) and Adrian Morejon (No. 86), meanwhile, is also 30 numerical places, but the difference in talent is relatively small. You may have noticed that there are more than 100 prospects in the table below, and more than 100 scouting summaries. That’s because we have also included 50 FV prospects who didn’t make the 100; their reports appear below, under the “Other 50 FV Prospects” header. The same comparative principle applies to them.

As a quick explanation, variance means the range of possible outcomes in the big leagues, in terms of peak season. If we feel a prospect could reasonably have a best big league season of anywhere from one to five WAR, that would be “high” variance, whereas someone like Colin Moran, whose range is something like two to three WAR, would be “low” variance. High variance can be read as a good thing, since it allows for lots of ceiling, or a bad thing, since it allows for a lower floor. Your risk tolerance could lead you to sort by variance within a given FV tier if you feel strongly about it. Here is a primer explaining the connection between FV and WAR. For further explanation of the merits and drawbacks of Future Value, read this.

You’ll also notice that this year, we’ve added probable FV outcome distribution graphs for each prospect on our list. This is our attempt to graphically represent how likely each FV outcome is for each prospect. Using the work of Craig Edwards, we found the base rates for each FV tier of prospect (separately for hitters and pitchers), and the likelihood of each FV of outcome. For example, based on Craig’s research, the average 60 FV hitter on a list becomes a perennial 5+ WAR player over his six controlled years 26% of the time, and a 27% chance of accumulating, at most, a couple WAR during his six controlled years. We started with these base rates for every player, then manually tweaked them to reflect how we think the player differs from the average player in that FV tier, since a player in rookie ball and a player in Triple-A with the same FV grade obviously don’t have exactly the same odds of success. So, these graphs are based on empirical findings, but with the subjectivity of our opinions included to more specifically reflect what we think the odds are of various outcomes. This is just a concept we’ve been kicking around for a while, one we hope to continue to refine to try to better communicate things about prospects.

What follows is simply a list of prospects who exceeded rookie-eligibility requirements in 2018. They are sorted into FV tiers (as listed at time of graduation) but not ranked within those tiers. Note the players whom we missed in the “Not Ranked” section at the bottom of the list. Lou Trivino (dominant reliever, probably should have been a 45 FV) and Niko Goodrum (a multipositional bat, typically a 45 FV for us) are prominent whiffs. Several of the 35 FV players were graded more highly in previous years (Fletcher, Laureano, O’Hearn, Palka) and they are a lesson in impatience and over-correction. Also take a gander at this piece from last winter, which I think has aged pretty well, especially the list of middle infielders.

It’s been a while since we posted anything comprehensive and transparent about how we draw our conclusions about prospects. Player evaluation and development are changing very quickly in the game, and those changes obviously influence how we think about prospects here at FanGraphs, enough to merit a refreshing primer before we start publishing this offseason’s organizational lists. In addition to teeing up the lists, this post is meant to act as a central hub that can serve to answer commonly asked questions about prospects and how they’re evaluated, specifically for those in the near future who want to start swimming in the deep end of the prospect pool. As we continue to augment our thinking and methodology, so too will we update this document, which will live in The Essentials section of the Prospects Coverage landing page. Feel free to direct any applicable correspondence to prospects@fangraphs.com. Common queries sent our way may find their way onto this webpage.

What information drives your opinions on prospects?

We see a lot of players ourselves. We talk to scouts from amateur, pro, and international departments about players they’ve seen. We talk to in-office analysts, front-office executives, and people in player development. We also use publicly available data we think is relevant. Some combination of these things fuels each player’s evaluation.

What are some of your shortcomings as far as information is concerned?

Increasingly, teams are using proprietary data as part of the player-evaluation process. TrackMan and Yakkertech aid evaluations on many different components of pitching and hitting, high-speed video of players from Edgertronic cameras allows clubs to better understand and alter hitting and pitching mechanics, and Motus sleeves and Rapsodo are used in pitch engineering. The mere existence and demonstrable efficacy of this stuff has altered the way we’re projecting players, but we don’t have access to the data generated by these devices across the entire population or prospects.

What is FV?

FV stands for Future Value, and it’s the way we distill each player’s scouting evaluation into a single expression. Broadly stated, Future Value is a grade on the 20-80 scale that maps to anticipated annual WAR production during the player’s first six years of service. But there’s also quite a bit of nuance underlying that definition, so let’s break down its components.

There are 6,000 or so minor-league baseball players at any given moment. By definition, meanwhile, there are only 100 minor-league ballplayers on any given top-100 prospect list. That means there are also around 6,000 minor leaguers not on top-100 lists — all 6,000 of them still intent on reaching the major leagues.

And many of them do reach the majors. For half-a-dozen years, Carson Cistulli has highlighted a number of prospects who failed to make a top-100 list by means of his Fringe Five series, and some of those players — like Mookie Betts and Jose Ramirez — have gone on to become stars. There should be little doubt that prospects outside the standard top-100 lists have value. Determining how much value, however, is a different and more involved question.

When I attempted to determine a value for prospects who’d appeared on top-100 lists, I was working with a relatively small pool of players. Even 15 years’ worth of lists equates to 1,500 players at most. Attempting to determine the value for every prospect, meanwhile, would appear to be a much larger task. Does one look at the roughly 90,000 minor-league seasons over the same period? That seems daunting. Looking at Baseball America’s team-level prospects lists, which feature 10 players per organization, would provide a more manageable 200 prospects per season outside the top-100 list, but that wouldn’t quite get us where we need to be, either.

And yet, as I’ve noted, these prospects have value. On THE BOARD, for example, there are currently 689 prospects with grades (a) of at least 40 but (b) less than 50 (the lowest grade earned by players on a top-100 lists, typically). It’s these prospects in whom I’m interested. What follows represents my attempt to place a value on them, as well.

Today, I’ve published a pair of posts in which I attempt to estimate the present-day value of prospects, both in terms of WAR and dollars. With that work complete, the logical next step is to turn away from the value of specific prospects and towards farm systems as a whole.

One can get a sense of the stronger and weaker systems just by eyeballing the rankings produced by Eric Longenhagen and Kiley McDaniel. What the prospect-valuation data allows us to do, however, is to place a figure on baseball’s top-800 or so prospects, creating a more objective ranking based on the grades assessed to each player here at FanGraphs.

These rankings provide a current snapshot of the farm systems before Longenhagen and McDaniel embark on their winter-long reveal of team prospect rankings. (The first post in their offseason series will appear this week.) As noted, the methodology for valuing prospects based on their grades is explained in my last two posts on the subjects:

• An Update to Prospect Valuation
• Putting a Dollar Value on Prospects Outside the Top 100

Keep in mind, these values are based on the current CBA, where players receive a minimum salary for roughly three years and then have three (or four) years of arbitration before reaching free agency after six full MLB seasons. Players are generally underpaid compared to their value on the field during these seasons, which is what creates the high present-day values and partially justifies the high value placed by teams on prospects when executing trades.

Over the years, a good deal of effort has been put into determining the value of prospects. Victor Wang, Scott McKinney (updated here), Kevin Creagh and Steve DiMiceli together, and Jeff Zimmerman have all published work on the subject, roughly in that order.

The reasoning behind such efforts is fairly obvious: teams trade prospects for proven players all the time. Finding an objective way to evaluate those trades is useful to better understanding how the sport operates. Indeed, FanGraphs has benefited from those prospect-valuation studies on multiple occasions.

With another year having passed, I’ve attempted to build on the work of others and produce updated valuations of my own. Previous efforts have been very helpful in the process, while the input of prospect analysts Eric Longenhagen and Kiley McDaniel has helped me find results that would be most useful.

In building this study, I set out with the following aims:

• To separate players into as many useful tiers as possible without creating unnecessary distinctions.
• To use as much data as possible so long as it was useful and likely still relevant today.
• To make the valuations as forward-looking as possible.
• To recognize that player development is not linear and that players appearing on prospect lists vary from major-league-ready to raw, Rookie-level talents.

To those various ends, here are some of the parameters of this study:

1. Baseball America’s top-100 lists from 1996 to 2010 serve as the foundation for prospect grades.
When I started the study, I looked at the lists dating back to 1990, separating out position players from pitchers and organizing by year. I found that the evaluations from the earlier part of the 90s — especially those for pitchers — had considerably worse outcomes than those that came after. I debated whether or not to throw out the data. Eventually, though, I decided that since 15 years of prospect numbers were showing decidedly different results, and that there was considerable turmoil occurring within the sport during that time — expansion, a strike, and a lockout — it seemed reasonable to toss the earlier years and go with the assumption that the 1996-2010 lists more accurately represented prospect evaluation today and going forward than the rankings of 25 years ago.

The 2018 trade deadline has passed and, with it, dozens of prospects have begun a new journey toward the major league with a different organization. We have the prospects traded since the Manny Machado deal ranked below, with brief scouting snippets for each of them. Players highlighted in blue are not technically prospects, having exhausted rookie eligibility, but we felt they fell under our umbrella of evaluation anyway as they’ve spent a lot of time up and down in the minors this year. Plus, it’s just interesting to think about where they fit. Scouting info comes from both in-person looks and also a combination of scouts and front-office personnel to whom we are eternally grateful.

Because they feature such a high concentration of pitching talent and because everyone’s stuff plays up in short stints, Futures Games are often fast-moving, low-scoring affairs. Since the game’s inception in 1999, for example, a team has scored three or fewer runs on 18 occasions. That was not the case on Sunday, however, as baseball’s top prospects combined for eight home runs. In the end, Team USA defeated Team World by a score of 10 to 6.

The end result of a prospect showcase like the Futures Game is essentially meaningless. Batting practice and infield/outfield drills, which occur before the cameras even turn on, are more informative. But, to me, the scouting-related feats of strength and athleticism seen throughout Sunday’s festivities (which I promise to address further down) were secondary to another development — namely, the number of and the performances by the game’s African-American players.

Only 7% of big leaguers are African-American, which is way down from about 27% during much of the 1970s. Articles about the declining number of black athletes in baseball have been written so frequently over the last half-decade that I assume readers are at least somewhat familiar with the issue, but if you’d like background, USA Today conducts the annual census. Like any shift of this magnitude, a confluence of variables is probably at the heart of what has caused this decline. Some of those are probably cultural, and this aspect of the decline is one about which people are quick to speculate , but, as a 29-year-old white guy, I’m not exactly qualified to discuss the African-American experience and how it does or does not intersect with baseball.

But I know the scouting process and, like many systems and processes in the United States, it has grown increasingly less suited for economically disadvantaged people — and people of color in this country are disproportionately poor. Showcases and travel ball are becoming a more significant aspect of scouting and player development in youth baseball. These cost money for the participants — to say nothing of flights to and from places like Florida and Arizona for several tournaments a year, mandated hotels in these locations, and the cost of breakable wood bats and other equipment. To take one example, each of the 328 teams participating in this week’s 2021 Class/Under 15 World Wood Bat Association Championship in Atlanta had a $2,500 entry fee, and it costs spectators $55 for a tournament pass and $5 to park. Baseball is a skill-based game and those skills are best refined against high levels of competition, but it’s expensive for an individual kid to play the kind of high-level baseball that helps develop those skills.

When I broach this subject with people in baseball, I’m met with some resistance from individuals who think the game is incentivized to mine as much talent as possible and that, poor or not, talent will be discovered. And while I agree with this premise, I think there are young athletes in this country who have the physical capability to play professional baseball but whom the scouting industry will never discover because that talent is never cultivated.

The 2018 MLB Draft’s signing deadline passed last week, and more teams failed to sign their early picks than is typical. Ultimately, four of the top 36 selections opted not to enter professional ball, all from the prep ranks. Those players are as follows: RHP Carter Stewart (Atlanta’s pick at No. 8), SS Matt McLain (Arizona at No. 25), RHP J.T. Ginn (Dodgers at No. 30), and Gunnar Hoglund (Pirates at No. 36). Scouting details on those individuals can be found on THE BOARD.

This has left those teams with one fewer prospect in their system than anticipated (all four teams get a compensation pick in next year’s draft), but more significantly, it moves a handful of premium talent into future draft classes. This year’s crop of unsigned high schoolers now serves as a preview of the college talent pool for the 2021 draft, but there are also a few 2020 prospects who are eligible early because they’re old for their class. There’s also a possibility that some could find their way into the 2019 draft class if they opt to attend junior college. We’ll reclassify players on THE BOARD as they change.

With that in mind, we thought it reasonable to present snapshots of each of the next three draft classes based on how we have the players graded right now. The industry’s evaluation of the 2019 class is already underway in earnest (Team USA, Cape Cod, and prep showcases are all occurring as we speak), and we’ve lined up a short list of the class’s top names thus far over on THE BOARD. Our 2020 list is mostly composed of the players we regarded as the best college freshmen this year, though we know of a few high schoolers who look like early first-round talents, too. The 2021 list is just a ranking of the high schoolers who didn’t sign in this year’s draft, exactly as they appeared on our 2018 draft board. We’re skeptical of prep players who have popped up this early because it’s often the result of physical maturity, but we don’t think that’s the case for Pennsylvania high school RHP Kevin Bitsko, whom we have evaluated similarly to the lean projection arms who are 40 FVs on the July 2 list.

We’re still too early in the process to make conclusive statements about the talent level of the 2019 draft class as a whole, much less the 2020 or 2021 varieties, so all this could change. As it stands now, however, the 2019 class collectively appears to lack the depth of the 2018 crop. By this time last year, we had a rough idea of how deep the high-school pitching was and knew that the Southeast had an overwhelming volume of talent. College hitting is the strength of next year’s draft class, and there’s lots of depth to the college crop in general, but the prep class lacks the quantity of players who are regarded as in-a-vacuum first rounders that one customarily sees at this point. Moreover, the college pitching class lacks a guy who looks like a top-five or -10 selection right now, though Casey Mize didn’t fit that criteria last summer and then ended up going first overall to Detroit in June.

We present the July 2, 2018 Board. It features scouting reports on players we have evaluated as a 40 FV prospect or better at the current moment (and we might add more reports over the weekend) as well as tool grades and some video. Specifics on the players in the class are reserved for the board itself, so head there if that’s all you’re looking for.

This is the second year of international amateur free agency under the current CBA, the rules of which were discussed here after they were first implemented. In short, teams now have a finite amount of money to spend on players. Here is each club’s cap for the period. The total pool space across baseball is about $159,000,000, or roughly $6 million above last year’s total.
