Coaching on pitcher F settings

F8 Lewis
F7
F6
F5
F4 Lackey
F3
F2
F1
F0 Greinke

I tried to search this a couple times and didn't come up with anything concrete as to how these work. My guess is that if you have a great pitcher or reliever, you can tolerate even a F1, but for middle of the road guys (aka. $4M SPs) a setting of F4 is probably more appropriate, $4M RPs would be F1s too. Has anyone written anything definitive on this? Any rule of thumbs to use?

John, who holds a blog on this forum, one of the employee of SOM, had this post a few weeks ago:

I also wrote on this topic not so long ago.

In my opinion, F0 means the pitcher has nothing left in the tank. I think it's too low even for a pitcher like Greinke.

Hope it helps.

Thank you very much.

No F0 for me now...I think I'll tweak things a little for my one high quality starter and my closer...but keep it at that...leave the others blank.
