By now you’ve heard that Mark McGwire has copped to using steroids during his career, but more specifically when he broke Roger Maris’ HR record in 1998. Shocking, I know. McGwire issued this admission to the Associated Press, but it will be MLB Network and Bob Costas that gets the first interview this evening….

MLB Network’s Bob Costas will have an exclusive in-depth television interview with Mark McGwire tonight on MLB Network live at 7:00 p.m. ET about McGwire’s admission of using performance enhancing drugs during his career. This is the first television interview granted by McGwire since he admitted using PEDs in a statement earlier today.

Following the exclusive interview, MLB Network’s Matt Vasgersian, Mitch Williams, Joe Magrane, Tom Verducci and Ken Rosenthal will discuss their reactions to the conversation. Costas will provide reaction from location in California and MLB Network’s Harold Reynolds and Peter Gammons will also provide commentary.

I’m one of the many people that followed McGwire’s every at-bat during that season, and while I don’t necessarily blame him for using steroids, this is something that should have come out years ago. Hiding that fact just makes me think he’s a scumbag. I’m hoping that Bob Costas conducts a better interview than Peter Gammons’ sitdown with A-Rod last year, but I doubt much of what McGwire says is going to make me change my views on him.
