The player pages now have some some additional usability features.

– You can now hover over any stat header and get the definition of the stat. This will soon make its way to all sections of the site.

– Seasons, Teams, and Positions are now linked back to the leaderboards. For instance if you are perusing Mike Trout’s page and you click on the Angels link in his 2011 season, it will bring you to the 2011 Angels leaderboards for the corresponding section.

There’s a new positional option for the leaderboards labeled NP (Non-Pitchers). This will exclude all players that qualify as pitchers from any of the batting leaderboards.

This works at both the team and league levels as well, making it easier to compare teams across leagues.

To better isolate batting and base running skills, SB and CS have been removed from wOBA and given their own category wSB.

What’s Changed?

wOBA, wRAA, wRC, wRC+ – These all no longer include SB and CS. SB and CS have been removed entirely from the wOBA calculation include the weights calculation.

Batting – Batting in the Value section no longer includes SB and CS.

Base Running – Base Running in the Value section now includes SB and CS.

FanGraphs Guts! – Our Guts! section now has updated weights and the SB and CS weights for use in wOBA have been replaced with the raw run values.

What’s New?

wSB – how many runs above or below average a player is at stealing bases.

UBR – (miscellaneous baserunning / advancement) is now broken out into a separate category which is in the Advanced section. This contains all the information that was formerly just in Base Running.

The Value (WAR) section for pitchers has been updated to help further break out a pitcher’s value. These stats are now available in the leaderboards and player pages.

We’ve added the following stats:

RA9-Wins – Wins above replacement calculated with RA9. This is both park adjusted and league adjusted.

BIP-Wins – Wins above average based on BABIP. This is both park and league adjusted.

LOB-Wins – Sequencing (and miscellaneous) wins above average calculated as RA9Wins – WAR – BIPWins.

FDP-Wins (Fielder Dependent Wins) – This is the full difference between RA9Wins and WAR, or BIPWins + LOBWins.

WAR – Wins Above Replacement remains unchanged.

Dave Cameron will have two posts with more details about these new stats at 9:00am and 10:00am and will be answering questions during his 12:00pm chat.

You can now filter your results on the FanGraphs leaderboards!

For instance, if you’re looking at the career leaderboards and you want to know which players had a career .300/.400/.500 slash line, this is now possible.

This also works out great for comparisons. For instance, here’s a single season list of starting pitchers since 1990 who had peripherals similar to Stephen Strasburg.

The filter feature allows for lots of flexibility and even more complex filters.

For the moment we didn’t include every stat we have and just some of the more common ones, but if there are stats you feel you must be able to filter on, let us know and we’ll try and add them to the list.

The PITCHf/x section for pitchers now contains splits by pitch type. You can now see all the usual stats for how a batters does against a pitcher’s individual pitches.

The splits are sorted by season and then by most pitches thrown, but you can also break things down by individual pitch, if you only want to view a particular pitch type.

I’m pleased to announce that The Hardball Times will be joining the FanGraphs family.

The Hardball Times has a long-standing tradition of excellent baseball writing and research, and we’re extremely happy to have them as part of our team. Dave Studeman and I plan on continuing the excellent tradition of bringing talented researchers to a broader audience.

THT will continue to operate as a separate site, keeping intact the strong THT brand. Over time we’ll make some changes and more tightly integrate the two sites as we see fit.

We’re really excited about the great work that will come out of our combined organizations.

Dave Studeman’s THT announcement can be found here.

FanGraphs has had some sort of user forums since it started and generally it’s a place where people go to ask questions about either the site, fantasy baseball, or sabermetrics in general.

Today we’re launching FanGraphs Q&A, which will hopefully allow for better discussion and allow for good answers to questions to be found much more easily than in the past.

To kick things off, we’re moving our RotoGraphs fantasy mailbag to FanGraphs Q&A where our RotoGraphs team will continue to answer questions and the rest of the FanGraphs community will also be able to chime in and help too.

Our game logs have been updated to include all the stats sections available on FanGraphs!

Here’s the full rundown of the new features:

– Includes the majority of our stats sections including the Dashboard, Standard, Advanced, Batted Ball, More Batted Ball, Win Probability, Pitch Type, Pitch Value, Plate Discipline and all PITCHf/x sections.

– Date filtering allows you to select the exact time range of a player’s career (dating back to 1974) that you want to see, even spanning multiple seasons.

– Minor League game logs are available for all players dating back to 2006.

In the FanGraphs Guts! page, you’ll now find a bunch of component park factors, included park factors by handedness.

All park factors are calculated using this 5 year regressed version.
