Amateur baseball, sabermetrics, active/passive investing, gambling, game theory.
I write for The Hardball Times. I own Driveline Baseball, where I coach some baseball players. I've written some web applications for baseball (Advanced Injury Database, Minor League Splits redux).
And once upon a time, I learned how to throw the gyroball and shared this with SoSH. That was quite some time ago. Let's forget about that.
