Bonds threatens boycott if Hall of Fame displays asterisk ball

The clock isn't yet ticking on his Hall of Fame candidacy, but Barry Bonds is already making waves in Cooperstown.

The former San Francisco Giants' slugger and current Major League Baseball home run king said Thursday night on MSNBC that he will not participate in any future Hall of Fame events, including his own induction ceremony, if the Hall displays his 756th home run ball -- a ball that has been emblazoned with an asterisk.
