I'm sure someone else here will go a little more in depth on this later (okay, I'm not so sure), but (shoulda-been-a)Hall of Fame Cubs third baseman and broadcaster Ron Santo has passed away:

I'm not going to lie - the last few years of Santo's broadcasting career made me hope he'd retire, but I'm pretty sad he's gone. Listening to him call a game was like watching it with one of your uncles - sure he'd lose track of who was up or what happened, but he definitely loved the Cubs and the sport of baseball - apparently in that order. And that has to count for something.

EDIT: You know, this upsets me more than I think I realized. Ron Santo is dead and Hawk Harrelson still walks the earth? No justice.
