At least SOME part of Mark McGwire belongs in the Hall of Fame ... so says Big Mac himself, who believes his 70th home run ball should be in Cooperstown STAT!!
"Bottom line," McGwire said out at LAX this week, "it should have been put in the Hall of Fame."
Of course, the ball can't exactly go there at the moment ... Todd McFarlane -- a legendary comic book artist -- famously bought it for over $3 MILLION just a few months after McGwire made history in 1998.
