The big news in the baseball world is Mark McGwire's admission that he used steroids, including in 1998 when he broke the MLB single-season home run record.

Anyone with a functioning brain and functioning eyes and even the most cursory knowledge of what steroids can do to a man's physiology already knew that McGwire was a user.

McGwire is doing an interview tonight with Bob Costas to discuss his admission. It will be broadcast on MLB Network at 7 p.m. ET and simulcast at MLB.com.

I hear Barry Bonds is planning to have his head shrunk and then do a similar interview in which he will obfuscate about every steroids-related question. (Okay, I made that last part up.)
