As I mentioned before, a deep pitching staff is critical. When it comes to hitting you need to pay attention to the power hitters. Some power hitters also hit for average and steal bases. Jeff Bagwell was a 5 catagory player last year. Some relief pitchers are also great strikeout artists but unfortunately, they usually only pitch around 70 innings a year.
Some relievers do get more strikeouts than many starters.
Billy Wagner got 124 K's in 74 innings last year. Ugueth Urbina also struck out 100 batters last year. Try to pick up two top notch relievers and two sleepers. Jock Rocker was a sleeper last year. Don't bother with middle relievers.
