More Win Probability!

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.
