To provide esoteric stats with esoteric names that can give more substance behind arguments on "who has the best pitch in baseball" and provide quantitative stats on the stuff of a pitcher.

All the stats are based off of Pitch f/x data from **last year**, except I included starts from Jeff Niemann and Clay Buchholz this year (prior to May 12th), since their curveballs are among
the best stuff-wise in baseball and there was only Futures Game data for the two last year.

The links containing the stats are below. The "Basic Data" gives stats like "contact rates" and "fish rates" for pitches of every single pitcher that had pitch f/x data last year (that's 625 pitchers). It also includes month-by-month pitch selection and pitch selection in certain situations such as "with bases loaded" or "in the 5th and 6th innings". The "Basic Raw Data" gives much of the same information as the basic data except in numbers and not percents, which would be particularly useful when looking at the pitch selection splits. The "Monthly/Locational Splits" gives contact rates and other stats for each month for the pitch and also how the pitch up in the zone or away from the hitter did. All three are .csv files and can be saved and opened in excel or can be opened in Zoho spreadsheets online for free by supplying the web address of the .csv files (the first and third are about 3 mb each so Zoho may crash your web server). The "leading pitches" links give the top 15 or so pitches per pitch type for the category and (for some categories) the worse pitches.

Be aware that the designating of changeups and fastballs and all else is not 100% correct, but it's not too far from it. The Pitch f/x data doesn't cover the whole 2007 season, but about half of the games and just about every game at the end of the season. There are certainly sampling issues with many of the pitchers and their pitches. In the "leading pitches" links I generally used a qualifier of 50 pitches, which is still a small sample. Lastly, stats may be called percents, but are actually left in ratio form in the way that SLG% or OBP are.

Leading pitches in terms of: Speed | Sink/Drop | Rise | Run/Cut | Total Spin | Downward Acceleration | Upward Accel. | Horizontal Accel. | Runs/100 | Contact Rate | BABIP | SLGBIP | Ground Out% | Air Out% | Swinging Strike% | Called Strike% | Strike% | Ball% | In Strike Zone% | Out of Strike Zone% | Fish Rate | Badball/ConOZ% | Swung at% | Command
