I added a couple of links today that you might enjoy.
Baseball Guru is a fantastic site that contains a treasure-trove of information. The Major Leagues, Japanese and Latin baseball, the Negro Leagues, original research, downloads-all kinds of good stuff can be found at Baseball Guru. I've had the site bookmarked for well over a year and just forgot to link to it. Consider the situation rectified.
Bill Burgess is one of the Gurus (and I checked and the genitive plural of guru is gurua but give me a break). If you want to know anything about Ty Cobb, check out Bill's page.
By the way, in case you're interested, the nominative plural of guru is gurui.
