"But, good luck convincing THT's Harry Pavlidis or Lucas Apostoleris to tag three and a half million pitches, because that would be insane. What’s that you say? They’ve actually done that?! By that, I mean individually tagged every pitch. This isn’t a very efficient solution, but it escapes the problems above by putting a human hand on the classification problem. Your mission, if you choose to accept us: Help us validate. How: 1) Run around like children in Wonka’s chocolate factory and consume as much data as possible (do not drink directly from the waterfall). 2) Using your knowledge of pitchers that you watch every day, let us know what looks wrong by starting threads on the BrooksBaseball.net Forums (we’ll have a thread for each pitcher, there are examples already there). 3) Use these graphs and tables however you want in any of your favorite blogs. Consult legal counsel first, and sign this waiver releasing us from liability. 4) Help us by sponsoring your favorite pitcher or two if you think what we’ve done is cool. This is an important step. Just like on Baseball Reference, you can add your own witty message to appear every time someone pulls up a card." Just amazing stuff from Dan Brooks, Harry Pavlidis, and Lucas Apostoleris.
