I thought I’d give everyone a little sneak peak at our long overdue leaderboards. The 4 different stat pages for batters and pitchers include pretty much all of the stats in the usual player pages. All the stats are sortable; just click on the stat name and it will sort in ascending order first and then if you click it again, it will sort in descending order.

The leaderboards are not integrated into the regular site navigation yet, but you can access them if you click here.

If you find any problems or errors, please let us know and feedback (bad or good) is always welcome.

Quite a few feature additions just went into production.

-First off, WPA is no longer expressed as a percentage. Every player still has the same value, it’s just 100 times less.

-WPA is now displayed in each player’s game log and all the dates in the game logs are linked back to the correct Win Probability graph.

-There’s a new table for both batters and pitchers in the player stat pages that include the following Win Probability & Leverage stats:

WPA: Win Probability Added.
-WPA: The total of a player’s negative contributions towards their team’s win/loss.
+WPA: The total of a player’s positive contributions towards their team’s win/loss.
pLI: Average Leverage on a plate-appearance basis.
inLI: Average Leverage when a pitcher starts an inning.
gmLI: Average Leverage when a pitcher enters the game.
exLI: Average Leverage when a pitcher exits the game (game ends not included).
Pulls: Number of times a pitcher has been pulled from a game before it ended.
G: The number of games pitched in.
phLI: Average Leverage when pinch-hitting.
PH: Pinch-hitting opportunities.
OBP Wins: Player’s wins in a context-neutral environment.
Clutchiness: Difference between WPA and a Leverage adjusted OBP Wins.

For more information about these stats, take a look at the following links:

If you notice any problems, please let us know and we’ll fix them as quickly as possible.

In the past, navigating you’re way through the Win Probability graphs was probably a bit of a pain since you had to go game by game until you got to the correct date. This was finally fixed today with the addition of a calendar where you can easily go directly to the game you’re looking for.

Additionally, the calendar is color coded so you can see which games were won (green) and lost (red) on each particular day they played. This may bring back some painful memories of some of the worst months in recent history like the Tigers’ 3-win April in 2003, or the Orioles 24-loss September back in 2002.

All the best months are in there too, such as the Athletics’ 17 straight wins to finish August in 2002 and the Red Sox’s 21-win August in 2004. Try it out and let us know what you think!

Update: It should be working for mac users now, but the formatting is going to be a bit off in safari until I can figure out what’s causing the issue.

You may have noticed that the Win Probability section has changed slightly. Thanks to our stats provider, Baseball Info Solutions (BIS), we now have 2002-2006 game logs, which we have used to compile the 2002-2006 Win Probability graphs and stats. Note that we were not using any of BIS’s data previously to compile Win Probability stats and you may notice that a few of the values have changed.

The data BIS provides is much more accurate than our previous data source and as a result there should be few-to-no errors. If you do happen to find an error, chances are it will be corrected the next day.

Hopefully there will be quite a few updates in the next week or two which should include:

– Play-by-Play for each game with Win Probability stats.

– Additional leverage statistics for relievers and pinch hitters.

– Win Probability +/- breakouts.

– Season Leaderboards. (FINALLY!)

– All Win Probability and Leverage stats in the regular player stats pages and game logs.

In the meantime, the 2002-2005 Win Probability data looks quite interesting, especially if you’re still debating the 2005 AL MVP race.

Tonight’s All-Star game was by far the lowest scoring All-Star game in the past 5 years, but it certainly did make for an exciting Win Probability graph thanks to Michael Young’s 2-out, 2-run triple in the top of the ninth. The National League was very close to pulling out a win, but in the end they still remain without a win in the past decade.

In today’s New York Times, Alan Schwarz takes a look at the All-Star selections by Win Probability Added.

“Most back-and-forths about All-Star selections focus on the player’s longtime all-starness (whatever that means) or, toward the statistical end of the spectrum, his runs batted in, his earned run average, even his on-base percentage plus slugging percentage. But if your image of an All-Star is his season-long contribution to victories, then the more blue-collar W.P.A. — Win Probability Added — could make your next All-Star symposium less, well, cheesy.”

As always, you can find the Win Probability sections here:

Win Probability: Individual Game Graphs & Stats
Win Probability: Team Stats

SportsIllustrated.com is currently running a feature on the great Albert Pujols. I was lucky enough to have my PitchZone charts included. You can find the article and all the PitchZone goodness here:

The Post-Gazette’s “Stats Geek” (Brian O’Neill) did a piece today on the Pirates lack of big hits in terms of Win Probability and Win Probability Added. If you’re a Pirates fan:

For further information on Win Probability and Leverage Index, you should head over to the Hardball Times:

Tom Tango: Critical Situations

Leverage Index (LI) is now available for all games and on a player-by-player basis. Much thanks to Tangotiger for letting us use his Leverage Index table to generate the graphs and player data. You can read more about Leverage Index here: Hardball Times: Critical Situations

There have also been some changes made to the Win Probability table which have resulted in some slight changes to Win Probability Added for each player. For the most part, all players should remain ranked the same in WPA, but pitchers should now have slightly more value than before and batters slightly less.

We’ve listened to your suggestions and have improved our Win Probability section by adding box scores, inning markers, and WPA season totals!
