I don't know how Steamer uses FIP,

[...]

It's not, because it doesn't account for Darvish's SBs and WPs,

These would seem to be mutually exclusive statements. You can't claim to not know the math behind Steamer and simultaneously claim it doesn't take into account SB's and WP's.

Thanks for the info on SIERA, I'll take a look.

Each pitch doesn't tie to a runner advancing.WPs and SBs do.In addition to his WPs, he gave up 30% of the Rangers' stolen bases.Together, they make a significant impact on his ERA.It could easily be 15%.

According to Tom Tango's run expectancy charts Darvish's SB - CS added ~3 runs to his season total last year. Finishing the math that means if Darvish didn't allow any SB's last season (nor any CS) he would have had an ERA of 3.71. When you do the math on WP's (which was ~3 runs as well) it works out to an ERA of 3.69.Combined they lower his ERA to 3.55.Or a difference of 8%.

I'm not sure what this has to do with the larger point though.Darvish > Lynn.

Edit:I hate not being able to put in 2 spaces after periods.
