For you pitching mechanics freaks out there, the cover story of this week's Sports Illustrated by Tom Verducci looks at The Freak himself, Tim Lincecum, and how his father helped him developed his crazy motion.  

Verducci also discusses mechanics in general, and there's some interesting stuff from Rick Petersen, who won't be out of a job for too long. 

It's a good read, check it out:
