IT MAKES STEPS TOWARDS QUANTIFYING CATCHER DEFENSE.
TOO COOL.

Still unquantifiable: Erick Aybar's socks.
Yes, that’s a random photo. But it’s a neat image. So there.
Try to survive the night.
(Aaaaahhhhh someone is quantifying catcher defense!!!)
Oh, and, uh, guys? I promise I’ll say something interesting over the weekend. Just a thought to get you excited for my upcoming angry ramblings and rants: Who do you think is having the best season? Andy LaRoche, Jason Bay, or Manny Ramirez?
Crane, yet again you’re awesome. The stats still make my head swim but I know a bunch of people will appreciate the info.
And despite his recent slump, I’d have to say Jason Bay.
Andy LaRoche. Only because his last name sounds vaguely French and I like to think he croons as a side project.
Don’t land on Joe Mauer! My poor team doesn’t need any more help in failing at life, and if the M&M boys were to get hurt, think it would be just too much.
PS, I also vote for Jason Bay.
