Pitch f/x

I don't have any analysis to add to this link just yet, but I just want to point out how cool it is. There is so much that can be gleaned from the information there. Just as a quick example of cool information I found within that database, did you know that the average velocity of a fastball leaving Joel Zumaya's hand last year was 97.85 mph? I haven't looked at every single pitcher in the database, but I suspect that is the highest number in the league. What could be even more interesting is the batter cards, which tell you what kinds of pitches were thrown to each batter so you can say things like "Alex Rodriguez saw more sliders than any other hitter in baseball." [Note: I have no idea if that is true or not.]
