Bill James Projections

In addition to the Marcel & CHONE projections, the projections from the Bill James Handbook are now available in the stats pages courtesy of Baseball Info Solutions. They will not be available in the leaderboard format on FanGraphs, but you can purchase them from Baseball Info Solutions here.

Just a quick note about how the projections are integrated: Batting Average, On-Base Percentage, Slugging Percentage, ERA, Runs Created, and Runs Created/27 were left as-is from the Bill James Handbook and were not calculated using the projected raw statistics; unlike the Marcel and CHONE projections.

This will probably be the last set of projections we add, unless someone else volunteers to throw their hat in the ring.


Stats Pages Updated

The 2007 Marcel & CHONE projections are now available in the regular stat pages. They will remain there until the 2007 regular season starts and will then be hidden to make way for the real 2007 stats. You’ll still be able to use the “Show Projections” button to see the stats after they are hidden; they just won’t be visible by default.

We’ve also added Balls and Strikes for batters, and corrected a bug in the daily split graphs.

Hopefully you won’t find the projections intrusive to your usual stat browsing. Please let us know what you think, especially if you don’t like it.


CHONE & Marcel Projections

Both Tom Tango and Chone Smith were both kind enough to let me post their 2007 player projections.

The Marcel (the Monkey) Forecasts are “the minimum level of competence that you should expect from any forecaster.” You can read exactly how they’re computed here: Marcel Methodology.

Chone Smith, on the other hand, has put a great deal of time and effort into his CHONE Projections. You can read more about his projection system and efforts here: Chone Projections.

There are two things I should make note of: I have used the FanGraphs positions for filtering by position where we have the player in our database. There are a number of minor league players in CHONE that aren’t in our database (yet) and for their positions we use those supplied in CHONE’s original file. And for the Marcels, we took the average of projected earned runs and base runs-earned runs and used that to display ER. This was how ERA was calculated in the original file anyway.

While I’m at it, there have been a few excellent discussions of projection systems recently:

The Hardball Times’ David Gassko did five part, Projection Roundtable, II, III, IV, V.

And Tom Tango recently asked “Who’s Smarter Than a Monkey?” followed by an insightful discussion in the comments.


Current Happenings at FanGraphs

Happy (belated) New Year everyone. If you haven’t noticed, FanGraphs now has all historical players dating back to 1871 after heavily massaging the data found at baseball-databank.org. More on that later.

With the 2007 season sneaking up on us, I thought I’d announce two things that FanGraphs has in store for next season that I’m very excited about.

1. FanGraphs will have nightly, accurate, minor league stats updates for all affiliated minor league teams. Sometime this month the 2006 minor league stats will be up on the site and we’ll continue to backdate minor league stats for as many players as possible in the hopes of having a complete as possible minor league database.

2. Real Time Win Probability will be available for all major league games. We’ll possibly have a beta/preview version up and running midway through spring training and try and squish all the bugs by the time the season starts.

On a side note, we’ve stopped collecting news data from blogs for the time being. I was not happy with how things were being categorized and found the whole thing not that useful. I’m hoping to have a new and improved system in place eventually.

In the meantime, enjoy the new historical stats & graphs and feel free to give us your feedback.


Baseball Analysts: Expanding the Strike Zone

There’s another article of mine up on Baseball Analysts about how the strike zone expands/contracts as the count changes and how different some pitchers take advantage of it.

“Ideally, a pitcher is going to try and get ahead in the count and when this happens the pitcher has effectively “expanded the strike zone” since the batter is now on the defensive and will be more prone to chase pitches outside the strike zone. Conversely, when a pitcher is behind in the count, a batter will be less prone to chasing bad pitches. Looking at OSwing by count this becomes fairly evident.”

You can find the rest of the article here: Expanding the Strike Zone


The FanGraphs Linkifyer!

I figured I’d share a little tool that FanGraphs and Baseball Analysts have been using internally for a little while now. Basically you paste the text of an article into the text box, select whatever parameters you want, and then hit the link button.

All the properly spelled, full player names will have hyperlinks to the stats pages on FanGraphs, giving your readers the option to see more detailed stats about that particular player.

Feel free to send us your suggestions and if you have any special requests that would make using the tool easier for your particular site, don’t hesitate to ask.

Postseason Stats

Career postseason stats have been added to the stats pages and 2002-2005 postseason game logs have been added to the game log pages

Post season stats will be updated throughout the playoffs with a 24-48 hour delay.


Sorry So!

A number of Win Probability aficionados have pointed out that So Taguchi was inacurately credited with -0.193 wins for his 8th inning lead-off walk. The problem has now been fixed and he has been accurately credited with 0.096 wins.

It’s worth noting that in this same game, Albert Pujols‘ home run was worth 0.624 wins and it was the 4th time this season he’s had a single at-bat worth more than 0.5 wins. He’s the only player, in the five years of win probability data I have, that has 4 hits worth over 0.5 wins in a single season. Since 2002, he’s had 6 such regular season hits, which is also the most in the majors. Make it 7 if you count his one post-season hit worth 0.716 wins:

Playoff Graphs!

Playoff Win Probability graphs have been added for the 2002-2005 seasons. Relive the joy/pain of the 2003 Aaron Boone home run, or see just how close the Giants were to winning it all in 2002.

From now until the playoffs we’ll be updating the various sections of the site with playoff stats to compliment our regular season stats. Also, don’t forget that FanGraphs will continue to have daily updated Win Probability graphs and all the usual stats throughout the 2006 playoffs.
