I have messed around with Fantasy Baseball in the past and joined a league my coworker started up this year. I have always played Fantasy Football and the strategy seems much more clear. The league I joined this year is a weekly head-to-head league with 8 scoring categories: 4 offensive (HR, RBI, SB, AVG) and 4 pitching (K, W, SV, ERA). 

Do any of you play Fantasy Baseball? If so, what's your strategy? Are there certain scoring categories you try to concentrate on instead of all of them?
