At FanGraphs we’re big fans of the heat map. And now customizable heat maps are now available in the pitchf/x sections for all pitchers. Much thanks to Dave Allen for helping me out!

The thing about heat maps is that one size does not always fit all. Depending on the density of pitches and how many pitches are thrown, it’s not always a clear cut case how to display the data. Sometimes you want the points bigger, sometimes you want the “intensity” of each point to be more and sometimes you really want a different color scheme. For instance here’s the same chart, but with the settings changed.

And here is a third chart, with the settings changed one more time, where the points are made smaller but very intense in monochrome.

There’s a lot to play around with here and a lot of options to try and get the best picture possible.

There have been a couple updates made to a couple of the stats on the site and some new data for 2010 added.

1. Total Zone and Total Zone with Location Data (TZL) are now available for the 2010 season. They’re in all the fielding sections, leaderboards, etc….

2. wRC+ has been updated to fix an issue with the league baselines. As a result for 2010, all NL players are now -4.01 and all AL players are -2.58. This will have some effect on all seasons with a similar uniform effect for AL and NL players. Big thanks to Kincaid for alerting us to the issue.

3. Pitcher BABIP has been updated to use TBF instead of estimating AB through IP. This has been a long time point of contention with our BABIP calculation. For years where TBF is unavailable, the old method is still being used (years prior to 1916 and most projection systems). As a result, BABIP’s for pitchers will show as lower than they were, but the baseline is also lower. The ordering of players remains extremely similar and the correlation between estimating AB’s using IP*2.82 and using TBF is about .99. The BABIP formula we are currently using for pitchers is (H – HR) / (TBF – BB – HBP – HR – SO).

Bill Baer of Crashburn Alley yesterday wrote an article titled, “FanGraphs Fan Projections Are Craaaaazy”. And there certainly was something crazy going on with some players on the Braves.

Long story short: I’ve made some updates and the Braves projections have returned to sanity and now look like this:

I’m pleased to announce that Joshua Maciel’s original WAR Grids are now automated for you to create your very own. Also a big thanks to Dave Allen for his help.

Here’s what one looks like for the top 25 WAR leaders since the year 2000.

I’d like to solicit the help of our community in building a useful fantasy player valuations guide. When we have the parameters set, I’ll code it and put it up on FanGraphs.

There are a couple goals here:

1. Building a useful and easy to use fantasy player valuation guide.
2. Full transparency in how all the rankings work.

I’ve dabbled in this a bit, so I will first give a starting point:

The selection of multiple seasons that was made available in the leaderboards section has now been rolled out to the team pages and My Team section sof the site.

Now it’s easy to find which Yankees player had the most WAR since 1996.

Or, which team had the worst offense since 2006.

On the leaderboards you can now filter by multiple seasons going all the way back to 1871.

There are a couple caveats, in that some sections of the leaderboard only go back so far. The Batted Ball, Pitch Type, Pitch Value and Plate Discipline sections can only go back to 2002, and the Win Probability section only goes back to 1974. Splits will also only go back to 2002 and monthly splits currently only for single seasons right now. I’ve included a label which shows exactly which seasons you’re looking at, even if you’ve selected something else.

For instance, if you’ve selected dates between 1980 and 2004 and you go the the Batted Ball section, you’ll only see the dates between 2002 and 2004.

If you’re filtering huge date ranges, please be a little more patient than usual because it may take a few seconds more to grab all the data.

This feature will be making its way to the other sortable stats sections fairly soon.

On all the leaderboards pages, you can now filter by all sorts of splits, including handedness, batted ball type, home/away, leverage, etc…

Want to know who the 4th best qualified pull hitter was last season according to wRC+? No problem; it was Paul Konerko.

How about which second baseman hit the most home runs against right handed pitchers?

Or even which pitcher had the lowest FIP on the road?

Splits filtering can also be done at the full team level, in the team pages, and in the My Team sections of the site.

The 2011 Fan Projections ballots are now open for you to project your favorite players!

Last year we ran the first annual Fan Projection ballot here on FanGraphs and you responded with over 50,000 ballots to make the project a huge success! According to Tangotiger’s Forecaster Challenge you collectively ranked 10th out of 21 overall. Not a bad showing for the first time around.

Here’s a quick look at the projection ballot:

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, there are 9 categories 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 2010, 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 this year 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 the player pages after there have been 15 ballots submitted.

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

For a limited time the FanGraphs iPhone app is on sale for $0.99.

Existing and new owners of the app will also find the 2011 Bill James projections in the player pages. I can also confirm that the app will include live and updated data for the 2011 season.
