Recently some friends of mine and I decided we wanted to figure out baseball, and it seemed to us that the best way to do it would be by starting up a fantasy baseball league. As someone who has never had any experience with sports, Yahoo was able to make it easy for me to learn. I've really been enjoying my experience with them and would absolutely recommend it to anyone who wants to try and break into sports fandom.
This site just keeps getting better, with more and more features each year. Whether you're joining your first "Pick 'em" game or serving as commissioner of a fantasy baseball league, you'll love this user-friendly site. I've tried others - ESPN.com and CBSSports.com and Yahoo! is by far the best.
