Below is KATOH’s 2018 top-100 prospect list. If you’re a regular FanGraphs reader, you likely know the drill by now. But in case you need a refresher, KATOH produces a WAR forecast for a player’s first six major-league seasons. It incorporates age, offensive performance, defensive performance, and other characteristics from the past two seasons. There are certainly drawbacks to scouting the stat line, but due to their objectivity, the projections can be useful in identifying prospects who might be overlooked or overrated.

I have made a few updates this time around. KATOH now features:

1. The batted-ball data (for both hitters and pitchers) available on our awesome leaderboards. Among other things, this helps KATOH differentiate between fluky and un-fluky high- and low-BABIP hitters.
2. A greater reliance on recent data for the construction of the model and less dependence on data points from 10-plus years ago.
3. Numbers from the Dominican Summer League, which was previously outside of KATOH’s scope

Astute readers might notice that this article does not include a top-100 for KATOH+, the version of KATOH that incorporates scouting grades in addition to the stats. Since Kiley and Eric are still working their way through the organizational lists, I don’t have up-to-date FV grades for every prospect. Rather than plugging in FV grades from a year ago (or more), I am holding off on KATOH+ for now.

The 2018 FAN Projection ballots are now open!

Before you can project any players, you’ll have to select the team you follow most closely towards the top of the screen. If you really don’t follow a team, just pick one. You’ll only have to do this once.

After you’ve selected a team, you can begin projecting players. There are nine categories of interest for pitchers and 10 categories for position players. Pick the values in the drop-down boxes closest to what you think the player will do in 2018. Hit the submit button and you’re done! If you made a mistake, you can always go back and change your selection at any time.

Please note that everything is a rate stat. You’re projecting 2B+3B, HR, SB, and Fielding as a measure of 150 games (basically a full season). The player’s previous stats are shown per 150 games in the projection ballot, too. This will make changing playing-time projections much easier, as you’ll only have to change the games played portion.

That’s really all there is to it. You can filter players by team or, if you go to the player pages, you can project players individually. If you want to see all the players you’ve projected, you can click on the “My Rankings” button, which will show you only what you specifically projected a player to do.

FAN Projections will show up on a player’s page after five ballots have been submitted for him.

If you do notice any issues, please let us know.

The Giants have acquired outfielder Andrew McCutchen in exchange for Kyle Crick and Bryan Reynolds. Below are the KATOH projections for Pittsburgh’s newest prospects.

The Astros have acquired right-hander Gerrit Cole (for real this time) from the Pirates in exchange for Michael Feliz, Joe Musgrove, and prospects Jason Martin and Colin Moran. Below are the KATOH projections for the latter two of those players.

Note that WAR figures account for each player’s first six major-league seasons. KATOH denotes the stats-only version of the projection system, while KATOH+ denotes the methodology that includes a player’s prospect rankings.

Colin Moran, 3B (Profile)
KATOH: 3.0 WAR
KATOH+: 2.8 WAR

The Marlins made Moran the sixth-overall pick back in 2013, but his stock has cratered since. His bat never developed the way scouts thought it would, culminating in a paltry .259/.329/.368 line in 2016. He showed signs of life last year, however, hitting .308/.373/.543 in his second crack at Triple-A. For the first time as a professional, he hit for power — largely by upping his fly-ball rate by 10 percentage points — while simultaneously cutting eight points off of his strikeout rate.

The Dodgers, Royals, and White Sox swung a three-team, six-player trade yesterday involving relievers Scott Alexander, Luis Avilan, and Joakim Soria plus three prospects: Trevor Oaks, Erick Mejia and Jake Peter.

Eric Longenhagen and Kiley McDaniel have provided scouting reports for the prospects changing hands. Below are the KATOH projections for those same players. WAR figures account for each player’s first six major-league seasons. KATOH denotes the stats-only version of the projection system, while KATOH+ denotes the methodology that includes a player’s prospect rankings.

Trevor Oaks, RHP, Kansas City (Profile)

KATOH: 3.4
KATOH+: 2.6

Oaks caught KATOH’s eye last year when he put up a 2.74 ERA with decent peripherals across 24 starts in the Dodgers system. An oblique injury effectively ended his 2017 season in July, but not before he recorded a 3.49 FIP and 21% strikeout rate in 84 Triple-A innings. Oaks turns 25 in March but has succeeded as a starter at the highest level of the minors.

The Giants have acquired Evan Longoria from the Rays in exchange for major leaguer Denard Span, plus prospects Christian Arroyo, Matt Krook, and Stephen Woods.

Below are the KATOH projections for the prospects received by Tampa Bay. WAR figures account for each player’s first six major-league seasons. KATOH denotes the stats-only version of the projection system, while KATOH+ denotes the methodology that includes a player’s prospect rankings. In total, my KATOH system projects these prospects for a combined 2.4 WAR (2.2 by KATOH+) over their first six years in the majors.

Christian Arroyo, IF (Profile)
KATOH: 1.5 WAR
KATOH+: 1.8 WAR

Arroyo missed a large chunk of 2017 due to multiple hand injuries and hit just .192/.244/.304 in 34 games with the Giants. Even without accounting for his small-sample big-league struggles, though, Arroyo’s track record doesn’t portend particularly great things. He hit a punchless .274/.316/.373 at Double-A in 2016 and his small-sample success at Triple-A last year was largely aided by his .427 BABIP. Arroyo’s youth and contact skills make him interesting, but he has very little power or speed and has already more or less moved off of shortstop.

This year’s Rule 5 draft came and went yesterday, with 18 players selected in the major-league phase of the draft. All the players selected will need to spend the entire 2018 season on their new team’s active roster (or disabled list). Otherwise, they have to be offered back to their original team.

Since most of these players do not have any sort of prospect pedigree anyway, I utilized the stats-only version of KATOH. WAR figures represent projections for the first six years of a player’s major-league career. For a scouting companion to this post, read Eric Longenhagen’s analysis from earlier this afternoon.

Players listed in order of draft selection.

1. Detroit Tigers
Victor Reyes, OF, 1.9 WAR (from D-backs)

Reyes has long been a KATOH darling. Look no further than his player page to see the articles in which he has been tagged.

KATOH has always believed in Reyes’s blend of youth, contact, and speed — a skill set he carried into Double-A last year. Reyes showed everything except for power as 22-year-old in Double-A last year. Given his 6-foot-3 frame, I wouldn’t be surprised if more power eventually shows up.

The Yankees have acquired reigning National League MVP Giancarlo Stanton from the Marlins in exchange for Starlin Castro plus prospects Jorge Guzman and Jose Devers. A possible $30 million in cash would also be included in the event Stanton chooses not to opt out of his mega-contract following the 2020 season.

Below are the KATOH projections for the prospects received by Miami. WAR figures account for each player’s first six major-league seasons. KATOH denotes the stats-only version of the projection system, while KATOH+ denotes the methodology that includes a player’s prospect rankings. In total, my KATOH system projects these prospects for a combined 5.9 WAR (5.2 by KATOH+) over their first six years in the majors.

Jorge Guzman, RHP (Profile)
KATOH: 3.3 WAR
KATOH+: 3.2 WAR

Acquired from the Astros last winter in the Brian McCann trade, Guzman dominated the New York-Penn League in 2017. He struck out a league-leading 33% of opposing batters this past season and walked just 7%. The end result was a 2.30 ERA across 13 starts. At 21 years old, Guzman wasn’t particularly young for short-season ball — especially for an international signee — but his performance was off the charts. As a result, KATOH has him as a top-150 prospect. Guzman is obviously several levels away from the majors, but there is a lot to like.

At long last, the hot stove appears to be heating up. In something of a surprise move, the Mariners have swung a trade with the Marlins to acquire both (a) Dee Gordon, who will apparently play center field for Seattle, and (b) $1 million in international slot money. In exchange, the Marlins receive three lower-tier prospects: righties Robert Dugger and Nick Neidert, plus infielder Chris Torres.

Below are the KATOH projections for the players received by Miami. WAR figures account for each player’s first six major-league seasons. KATOH denotes the stats-only version of the projection system, while KATOH+ denotes the methodology that includes a player’s prospect rankings. In total, my KATOH system (both stats-only and KATOH+) projects this trio for 3.6 WAR over their first six years in the majors.

Nick Neidert, RHP (Profile)

KATOH: 2.2 WAR
KATOH+: 2.7 WAR

Seattle took Neidert in the second round out of high school back in 2015, and he promptly began mowing down low-minors hitters. Neidert opened 2017 as a 20-year-old in High-A, where he pitched excellently — his strikeout rate, walk rate, ERA, and xFIP were all top-five in the Cal League among pitchers with at least 80 innings pitched. Neidert’s performance cratered following a late-season promotion to Double-A, but his body of work is impressive. He rarely walks anyone and has shown an ability to miss bats against much older competition.

The deadline for teams to set their 40-man rosters in anticipation of the Rule 5 draft was Tuesday, November 21st. This means that all Rule 5-eligible players who aren’t currently on a 40-man roster will be available in the draft on December 14th at the Winter Meetings in Orlando. Here’s what makes a player Rule 5-eligible, according to MLB.com:

Players who were signed when they were 19 or older and have played in professional baseball for four years are eligible, as are players who were signed at 18 and have played for five years.

For the coming version of the Rule 5 draft, that’s generally any player drafted out of college in 2014 or earlier, drafted out of high school in 2013 or earlier, or signed as an international free agent in August 2013 or earlier. But that’s just a rule of thumb, and since very few things in life are simple, there are exceptions and loopholes.

Most of the players listed below aren’t good prospects. If they were, their teams would have protected them — or traded them to a team interested in stashing them. The baseball industry has effectively deemed each of these players to be a fringe prospect at best. Who cares about these mostly bad baseball players? Probably a very tiny sliver of the world’s population, if I’m being honest. But if you you’re still reading, I’m willing to bet you’re part of that small minority. And besides, several Rule 5 picks from recent memory have enjoyed immediate big-league success, including Joe Biagini, Matt Bowman, and Odubel Herrera.

Below, you’ll find a list of KATOH’s favorite Rule 5-eligible prospects, grouped by position. Due to the aforementioned loopholes, along with the fact that I checked each player’s eligibility manually, it is possible I omitted a noteworthy player along the way. All players with at least 200 professional plate appearances or batters faced in 2016 or 2017 were considered. Since most of these players do not have any sort of prospect pedigree anyway, I utilized the stats-only version of KATOH.
