SB Nation has come up with their own version of fantasy baseball. It's called 'Pick 6' and it is totally different from the traditional way of playing the normal style of what was originally called Rotisserie Baseball. 'Pick 6' is a free game that you can play with your own group of friends, or even by each website like Baltimore Beatdown.
Just click on the link above to get to the site and "draft" your own team managing the $120 salary cap. Then 'Pick 6' automatically tracks your players' stats and comes up with a point total for the day's final score. Each day's games start anew with the key players from each team available to be part of your team and their "salaries" for that day must total no more than your $120 salary cap (too bad MLB doesn't have a salary cap!).
I tried it when it was still in it's development, or "beta" stage, and it was really cool. Give it a shot.
