I have always believed that gambling wwebsites are an under appreciated source of fantasy information. Helpful for spot starters by looking at the lines. They can also help chose which position players to start by looking at over unders. Granted, it's not gospel, but when you have two really close players it sometimes helps me make a decision.
I have a link to umpire stats at home, but here
is one I just found quickly. It looks as if Diaz has a wider strike zone, calling 15.6 SO per game (7th of 50 or so).
From what I remember of the Lincecum debut game, his strike zone was tight the first few innings and then really expanded after that. I think he started calling a lot more high strikes past teh half way point of the game.
