ESPN - Bonds will boycott Hall of Fame if ball has asterisk - MLB
NEW YORK -- Barry Bonds would boycott Cooperstown if the Hall of Fame displays his record-breaking home run ball with an asterisk.

That includes skipping his potential induction ceremony.
"I won't go. I won't be part of it," Bonds said in an interview with MSNBC that aired Thursday night. "You can call me, but I won't be there."
The ball Bonds hit for home run No. 756 this season will be branded with an asterisk and sent to the Hall. Fashion designer Marc Ecko bought the ball in an online auction and set up a Web site for fans to vote on its fate. In late September, he announced fans voted to send the ball to Cooperstown with an asterisk.
Of course, the asterisk suggests Bonds' record is tainted by alleged steroid use. The slugger has denied knowingly using performance-enhancing drugs. Fans brought signs with asterisks to ballparks this season as he neared Hank Aaron's career home run mark.
Bonds has called Ecko "an idiot."
