I've been messing around with a baseball statistics database I downloaded the other day (http://www.baseball-databank.org). I have a searchable, by player name, section done. It's at http://stats.baseball-wiki.com if anybody wants to check it out.
I plan on expanding it so that top # lists for various stats can be pulled from it, along with team stats and various other things. Its very much a work in progress, so if it's acting up when you check it I'm probably debugging some mistake I made .
Thanks to Cyclone for helping me along with some of the formulae.
