McGwire admitted Monday that he used steroids for a decade, including when he hit 70 homers in 1998, but denied Canseco’s claims that he injected himself and McGwire with steroids in bathroom stalls.

“I’ve defended Mark, I know a lot of good things about him,” Canseco told ESPN 1000 radio in Chicago on Tuesday. “I can’t believe he just called me a liar. Umm, there’s something very strange going on here.

Canseco is now calling manager (Tony La Russa) a liar because he didn’t know that McGwire used steroids.

“That’s a blatant lie,” Canseco said. “There are some things here that are so ridiculous, and so disrespectful for the public and the media to believe. I just can’t believe it. I’m in total shock. These guys remind me of politicians that go up and just lie to the public and expect to get elected.”

Canseco, who blew the whistle on many players in his 2005 book, “Juiced: Wild Times, Rampant ‘Roids, Smash Hits, and How Baseball Got Big,” is still trying to stay in the spotlight, but for all the wrong reasons.

Why would a steroids offender try to upset the baseball world? IMO he needs the money and the spotlight.

Sorry to say, but Jose walk away!

McGwire is bad for the game period! He hasn’t been honest with himself, Congress or his fans. McGwire has been unwilling to answer allegations about performance-enhancing drugs. Big Mac may have to answer questions now that he is back in the spotlight.

I am not a fan of any player that cheated during the steroid era. It is a shame that Mark McGwire was part of this era as he and Sammy Sosa in a way, saved baseball during the Home Run Derby of sorts.

La Russa must be dreaming or did he pass out in his car again? Stop hitting up happy hour Tony! Do you really want that kind of media attention considering that you have only named him and not introduced him publicly as your hitting coach?

Big Mac just needs to stay at home and hope he will be forgiven and maybe have a chance to be voted into the Hall of Fame.
