Outfield Defense Redux

I've made some changes to the SFR system for outfielders based on excellent feedback from readers and others that I discuss in today's column appropriately titled "Back to the Drawing Board". One of the things you'll notice is that my correlations for right fielders (primarily because of Brian Giles and Juan Encarnacion) with UZR for the 2003 through 2006 period are very poor. Not sure why but I noticed that Sean Smith apparently has similar issues. Overall, I like the system better and it seems to handle Manny Ramirez better and correlates pretty well with UZR overall.

As a bonus you can now download a spreadsheet with version 1.0 of SFR for the infielders that includes 2007 minor league data.

Very excited about the minor league data. Huge props for making it available and easily used.

Just have to add - the minor-league data absolutely makes you my hero, Dan. Thank you so much.
