Baseball-Reference I take the raw data and input into an Excel Spreadsheet. I have all the stats ready to auto-compute, including RC, FIP and xFIP. It isn't hard once you know the formulas. It just takes time to input all the data. I usually start once the season is over and sometime complete it before Spring Training, in time to set up any fantasy teams I have. I have on spreadsheet for pitching and one for hitting.
ESPN is good for quick player splits.

Just go to a player's profile page. Go to splits and change the dropdown to the last 3 years.
Fangraphs can be used also, especially when viewing large amount of players at one time.
