With the pitch clock and a slew of other rule changes now in effect in the majors, we’ve added a section to the leaderboards dedicated to tracking all manner of rule violations and their run values.

Some important notes:

– The violations include Pitcher Pitch Timer Violations, Catcher Pitch Timer Violations, Disengagement Violations, Defensive Shift Violations, Batter Pitch Timer Violations, and Batter Timeout Violations. Read the rest of this entry »

I’m happy to announce that we now have two pitch quality models, PitchingBot and Stuff+, available for your perusal on the FanGraphs Leaderboards.

PitchingBot is the brainchild of Cameron Grove. We worked with Cameron to be able to run and maintain his model in-house at FanGraphs; he has since joined an MLB front office. You can read all about PitchingBot in the FanGraphs Library here.

In short, PitchingBot takes inputs such as pitcher handedness, batter handedness, strike zone height, count, velocity, spin rate, movement, release point, extension, and location to determine the quality of a pitch, as well as its possible outcomes. Those outcomes are then aggregated and normalized on a 20-80 scouting scale, which is what is displayed on the leaderboards. Read the rest of this entry »

We’re excited to announce that Negro Leagues data is now available on the FanGraphs player pages and leaderboards! In addition, Negro Leagues players now have FanGraphs player pages. All data is provided by The Seamheads Negro Leagues Database powered by Agate Type Research. Special thanks are due to Gary Ashwill and Kevin Johnson for their assistance as we incorporated the data into the site.

The seven Black baseball leagues included in our data mirror those at Baseball Reference and are consistent with the recommendations of SABR’s Negro Leagues Task Force and Major League Baseball’s announcement recognizing these leagues as being major leagues.

FanGraphs is now accepting applications to join our staff as a contributing writer.

Contributors typically write two to three times a week. Familiarity and comfort with the data here on FanGraphs is a requirement, but just as importantly, we’re looking for writers who can generate their own ideas and questions while providing interesting analysis or commentary on the game of baseball. From free agent signings to statistical analysis, teams’ top prospects to in-game strategy, highlights to lowlights, we want to cover it all. Sometimes we do that with a bit of silliness; other times, we’re more serious. But what all of our work has in common is a commitment to asking interesting questions and using rigor, creativity, and the latest analytical tools to find the answers for our readers.

4/23 Update: It has come to our attention that in the switch to Statcast Fielding Runs Prevented (RAA), outfield positional adjustments were being improperly applied. This has now been corrected by zeroing out RAA for each individual position, on a seasonal basis, specifically for use in WAR. The tables below have been updated to include this correction.

Since we launched FanGraphs WAR in 2008, we have used various components of Ultimate Zone Rating (UZR) such as Range, Outfield Arm, and Double Play Conversion to evaluate position player fielding. Today, we’re changing one of those components. Retroactive to the 2016 season, we have swapped out the Range component of UZR for the Statcast metric Fielding Runs Prevented, which is Outs Above Average (OAA) converted to runs above average. The UZR Outfield Arm and Double Play Conversion components of WAR remain unchanged.

We believe the additional data points available in Statcast, such as a fielder’s starting location, help to improve the measurement of a player’s range, especially in situations where players are shifted.

The vast majority of players’ new WAR calculations fall within a +/-1 WAR range of their previous WAR figures. Since 2016, there are 49 individual seasons that have changed by more than one win, and 14 players whose WAR has changed by more than three wins for the entire six year span starting in 2016.

Weather data is now available on the FanGraphs Splits Leaderboards.

You can filter any data since 2010 by temperature, barometric pressure, elevation, wind speed, wind direction, and air density. To make the weather data more useful, you can also filter on the specific ballpark, roof type, and the roof open/closed status.
