It's got a page for every player, team, manager, league, and postseason in history. Do you want to know who was the active leader in home runs in 1943? It's got it (Jimmie Foxx). Do you want to find all baseball related attractions within 50 miles of Wahoo, Nebraska? It's got it (the Omaha GoldenSpikes are 35 miles away). Do you want to find a random player? No problem (I got Scott Medvin, who went 3-2 for the Pirates and Mariners between 1988 and 1990).

In essence, it's the (duh) best baseball reference site on the web. For each player, it gives you their season-by-season numbers (hitting, pitching and fielding), their postseason stats, a chart of all their awards and top ten finishes in statistical categories, and a list of players with the most similar statistics. I could spend all day playing with this site, but then I'd get fired from my job, and I'd have to sell my computer for food money, so that would kind of defeat the purpose.

These guys write a yearly book (which is excellent), as well as write some top-notch articles throughout the year on their site. Things get a little slower on the web-page front this time of year, since they're actually writing the book now, but they've got an excellent staff of writers and statisticians. If you've never checked out their book, it contains blurbs on pretty much every major leaguer and significant minor leaguers in baseball. It's always my first reference when someone is traded for prospects that I'm not familiar with. But back to the web site - the Baseball Prospectus guys can fill all your baseball needs, whether they be statistical studies, articles on the economics of baseball (their some of the few people who get it right, in my opinion) - basically they cover it all.

Everyone has their favorite sports news source, but I've always stuck with ESPN, primarily for two reason. One is Rob Neyer, who writes a very good column, and two is Peter Gammons, who is always entertaining (by which I mean we can laugh at him, if not always informative). But besides the columnists, I like to have a web page open all day, so I can keep up with whatever's happening - especially this time of year, with all the signings and trades going on. The Baseball Prospectus staff occasionally has columns on ESPN as well, and John Sickels, the minor league guru, has an ongoing column. I usually find a few new things on here to read each day, whether they be new columns, or just news events.

Another good daily column - Strikethree rotates their column between a few different people, but the columns are all always interesting, and usually poke fun at someone (Bud Selig, Rey Ordonez) who really deserves it. It's on my list of web pages I look at each morning.

That's the best of the best - have fun checking them out! <!-- Article Ends Here --!>
