As is tradition at FanGraphs, we’re using the lead-up to the trade deadline to take stock of the top 50 players in baseball by trade value. For a more detailed introduction to this year’s exercise, as well as a look at the players who fell just short of the top 50, be sure to read the Introduction and Honorable Mentions piece, which can be found in the widget above.

For those of you who have been reading the Trade Value Series the last few seasons, the format should look familiar. For every player, you’ll see a table with the player’s projected five-year WAR from 2027-2031, courtesy of Dan Szymborski’s ZiPS projections. The table will also include the player’s guaranteed money (exclusive of any signing bonus), if any, the year through which their team has contractual control of them, last year’s rank (if applicable), and then projections, contract status, and age for each individual season through 2031 (assuming the player is under contract or team control for those seasons, or has a player option). Last year’s rank includes a link to the relevant 2025 post. Thanks are due to Sean Dolinar for his technical wizardry. At the bottom of the page, there is a grid showing all of the players who have been ranked up to this point. Read the rest of this entry »

The concept of trade likely predates written history. If one person has a thing, and another person has a different thing, you better believe that they’re both thinking about whether they’d be better off by swapping those things. That means that the concept of value is almost as old; if things can be swapped, then it’s important to rank them so that you don’t make a bad deal and end up with something worse than what you started with. In other words, trade value lists are one of the things we humans have done the longest. Or at least, that’s what I like to tell myself to feel better when it’s 11:47 PM and I’m wondering whether I’d rather have four years of a shortstop or three years of a mid-rotation starter.

Welcome to the 2026 FanGraphs Trade Value Series. Starting today and continuing through the end of the week, we’re releasing our list of the 50 most valuable players in baseball, taking player performance, age, and contract details into account. Dave Cameron, Kiley McDaniel, Craig Edwards, and Kevin Goldstein have all headlined this list before; this is my fifth year doing it on my own.

Of course, I really ought to put “on my own” in quotation marks. I start building this list by gathering every input I can think of. Age, contract status, current statistics, projected future performance, Statcast data, pitch- and arsenal-level modeling, scouting reports – if it can be written down, I try to consider it in my first pass. I use all of those inputs to come up with an initial set of rankings, then refine those rankings by diving deeper into individual player comparisons. After I have things in relatively good order, I consult with the FanGraphs staff to clarify my thinking further and get new opinions on tough decisions. Everyone is a big help, but special thanks are due to Dan Szymborski for supplying the ZiPS projections, Sean Dolinar for his technical assistance, and Meg Rowley for patiently shepherding the project from a spreadsheet to the final product. Next, I reach out to sources on the team side. Here, I try to gather perspectives from organizations with different methodological leanings, budgets, goals, and places in the competitive cycle; basically, as many differing viewpoints as possible.

Every July, we release our annual Trade Value Series highlighting the top 50 players in baseball, taking contract status and performance into account. For the past five years, I’ve been in charge of that exercise, with liberal amounts of help from the rest of the FanGraphs staff and some contacts on the team side. Last year, we added a new evaluator: You.

Today, we’re excited to announce the return of our crowdsourced trade value tool, which can be found here. Let’s review how it works, just in case you didn’t spend last year’s All-Star break furiously clicking through it when you should have been working. The tool, created by Keaton Arneson, and developed by Keaton and Sean Dolinar, aggregates simple “Which of these two players do you prefer?” questions to create a composite ranking. Using the tool is simple. When you pull it up, you’ll be presented with two players and asked to choose which one you think has a higher value in trade:

Ah, but what does “higher value” mean? Sometimes the simplest questions are the toughest. Having a higher value in trade isn’t the same as being better, or being younger, or having a more team-friendly contract. It might be some combination of those things, of course, and of other factors as well. In the real world, players have differing levels of value to teams based on a host of considerations, from how well they plug a hole left by a recently injured star to where the team finds itself in the playoff race. A promising prospect might mean more to a rebuilding club, just as a proven difference maker might move the needle for a team with October ambitions. We can’t tell you how to weigh these factors, which is part of the fun of constructing a trade value list in the first place. What we can do is provide some data that we consider useful in making such determinations and let you decide how to apply it. Read the rest of this entry »

It’s generally bad process to evaluate a player based on a hot or cold streak. Everyone has them, and if you only look at a guy’s best or worst stretches, you’re liable to see things that aren’t really there. That’s just how baseball works; no one plays at the same level all the time. Sometimes the ball looks like a grapefruit, sometimes it looks like a grape. Sometimes pitchers dot the corners with aplomb; sometimes their 3-0 offerings fly wide. No one’s ever as good as they look when they’re on top, or as bad as they look when things aren’t landing. But just because hot streaks are resistant to analysis doesn’t mean they aren’t fun. And for my money, there’s no player who’s more enjoyable to watch when he’s firing on all cylinders than Juan Soto.

In the aggregate, Soto is on track for another successful year, with numbers that look roughly in line with his career marks. His .414 OBP is a hair lower than his career number, but he’s hitting for a bit more power than normal, and striking out less, hence a .570 slugging percentage that would be one of the highest of his career. An early-season injury means he won’t hit his normal 700 plate appearances, and of course the Mets are a dumpster fire, but if I put a bunch of years of Soto’s rate statistics up, you’d struggle to separate this season’s numbers from the pack. That’s basically the idealized pitch for Soto: He can roll out of bed and post a 160 wRC+ with a .400 OBP.

That’s just in the aggregate, though. In the last 30 days, he’s batting .325/.472/.578, good for a 190 wRC+, and walking nearly three times as often as he strikes out. Are these arbitrary endpoints? Of course, and Soto’s not even the best hitter in baseball over that stretch. Batters can do almost anything for a month at a time. Pete Crow-Armstrong is slugging nearly .800 over the last 30 days. Heck, Soto is flanked by Luis García Jr. and Kyle Karros on the wRC+ leaderboard over the last month. It’s not about the raw production. But the way he does it? Man, I can’t get enough.

Today at FanGraphs, we’re introducing an updated approach to prospect valuation. You can read the announcement here, and also see the new Farm System Rankings for 2026 on The Board. This post is a detailed methodological examination of how we’ve produced our new estimates. It goes over each step of the process in order, and concludes with a sensitivity analysis. If you’re interested in the broad strokes of our new approach, the introductory post will likely suffice. But if you want to see how the sausage is made, read on.

Prospect Classes
We began with Baseball America’s annual Top 100 prospect lists for each year from 2005-2016, plus FanGraphs’ lists for 2017 and 2018. The BA lists serve as a publicly accessible bridge to the current era of FanGraphs prospect writing, and provide a nice through line with Craig Edwards’ earlier research. We took all instances of a prospect being ranked, including duplicates of the same prospect in multiple years. We converted those ordinal rankings into Future Value grades using a two-step process. First, we separated the rankings into pitchers and hitters and created two separate ordinal lists for each year. Second, we adjusted those ordinal rankings between years by a regressed factor based on that class’ major league production. This allowed us to differentiate between classes – without some type of delineation between years, every top overall hitter would receive the same grade, which is contrary to the way we grade prospects.

This method introduces some potential bias. Judging prospects based on how they turned out inherently brings some information from the future into the mix. We decided that this was the best possible way to systematically introduce varying year-over-year quality to an otherwise ordinal-only set of values, and that it also did a good job of replicating the way that grades might have actually been assigned in the past. The top pitching prospect on the 2010 list was Stephen Strasburg. The top pitching prospect on the 2011 list was Julio Teheran. It’s important to differentiate between the likely grade that they would have received. There’s some volatility in relative value assignment at the very top end of the scale based on this methodology, which is addressed in the sensitivity analysis. Read the rest of this entry »

Seven years ago, Craig Edwards published a landmark study on prospect valuation. Craig’s work built on previous studies by Victor Wang, Scott McKinney, Kevin Creagh, Steve DiMiceli, and our own Jeff Zimmerman, as well as a few prior ad hoc attempts here at FanGraphs; subsequent work on the subject was done by the team at Driveline Baseball. These studies have been hugely important both for FanGraphs’ own evaluation of prospects — among other things, Craig’s work has helped to feed the Farm System Rankings over on The Board — and for the broader public study of the minor leagues.

The reasoning behind these studies is clear and simple. If you want to evaluate a prospect-for-big-leaguer trade, you’ll need to know the expected value of the prospect in the trade. If you want to evaluate how much help is waiting in a given team’s farm system, a quantitative assessment of the talent there is necessary. Even if you’re just wondering how likely your team is to find the next big thing, again, you’ll need some type of framework to understand how often that’s happened in the past.

The previous studies of prospect valuation are still excellent, but they’re all very much of their time. Since Craig published his study in November 2018, the league has changed significantly. The COVID-abbreviated 2020 season changed minor league timelines across the board. The league contracted the number of minor league franchises significantly in 2021. A new CBA, signed before the 2022 season, changed compensation structures and competitive balance tax levels, and introduced the Prospect Promotion Incentive. The cost of a win in free agency has skyrocketed; league-wide payrolls are up more than 30%, and free agent salaries are up by more than that. Read the rest of this entry »

Right off the bat, I have to tell you that I don’t love the name I gave the statistic I created last week. RE-RA9 doesn’t exactly roll off the tongue. The concept – adjusting run-scoring statistics to account for inherited runners – is easy to get your head around, and I think it’s clearly interesting. But while I had fun writing that article, I wasn’t quite happy with where I left off, either on the name front or on the analysis front.

The name thing probably can’t be fixed. I’m not a great namer of things, historically, and I don’t think that’s going to change today. But while I can’t do anything about that, I quickly expanded my coverage from 2026 to, well, as much of baseball as I could. If this statistic is interesting, it’s interesting as much for its application throughout history as for who’s good and bad at it this year. So with the help of the FanGraphs play-by-play database, which stretches back to 1974, I built RE-RA9 for the vast majority of the era where there were enough relief appearances for this statistic to even make sense. Forget Grant Anderson and Chase Silseth, the two poster boys from my first article. Let’s get some famous guys and seasons in here.

For example, here are the 10 pitchers who have done the most to prevent inherited runners from scoring (RE-RA9 lower than actual RA9), minimum 1,000 innings pitched:
