I've never really used the Wikipedia as a baseball reference, but there's some good stuff there. One neat thing is that if you click on the Dodgers article and scroll down, you get the current roster. Okay, that's not the neat part. You can find the roster in lots of places, and it'll likely be more up to date in lots of them. The neat part is that this one has little flags in front of each player's name showing his country of origin. Turns out Edwin Jackson was born in Germany (his dad was in the US Army, and was stationed there at the time).
There's also a brief article on the Dodgers-Giants rivalry. Good stuff.
