Adding to the blogroll...

After a summer of apparently watching soccer, Voros McCracken has come back with a new blog. Voros is a baseball sabermatrician who has worked with the Boston Red Sox, and the creator of DIPS (Defense Independent Pitching Statistics). (I'll link to the studies once I find copies out here on the interweb. EDIT: Your first link, a summary of the theory and why it works by David Gassko.)

It's a must read for anybody interested in baseball.
