The ball Barry Bonds hit for his record-breaking 756th home run will be branded with an asterisk and sent to the Baseball Hall of Fame.

A fashion designer, Marc Ecko, who bought the ball in an online auction, set up a Web site for fans to vote on the ball’s fate, and today announced the decision to brand it won out over the other options — sending it to Cooperstown unblemished or launching it into space.

Ecko said he believed the vote to brand the ball showed people thought “this was shrouded in a chapter of baseball history that wasn’t necessarily the clearest it could be.”

Ecko, whom Bonds called “an idiot” last week, had the winning bid September 15 in the online auction for the ball that Bonds hit August 7 to break Hank Aaron’s record of 755 home runs. The final selling price was $752,467, well above most predictions that assumed Bonds’ status as a lightning rod for the steroids debate in baseball would depress the value.

The asterisk suggests that Bonds’ record is tainted by alleged steroid use. The slugger has denied knowingly using performance-enhancing drugs. Fans brought signs with asterisks on them to ballparks as he neared Aaron’s hallowed mark.

A Bonds publicist, Rachael Vizcarra, did not immediately respond to an e-mail sent early today seeking comment about the ball’s fate.

The president of the Hall of Fame, Dale Petroskey, said accepting the ball did not mean the Hall in Cooperstown, N.Y., endorses the viewpoint that Barry Bonds used drugs.

“This ball wouldn’t be coming to Cooperstown if Marc hadn’t bought it from the fan who caught it and then let the fans have their say,” Petroskey said. “We’re delighted to have the ball. It’s a historic piece of baseball history.”

Hall of Fame officials and Ecko are discussing how to affix the asterisk on the ball. It’s not yet known when the ball will go on display.

The Giants announced Friday they will part with Bonds after this season, the seven-time NL MVP’s 15th in San Francisco and 22nd in the majors.

Ecko, known for his pop culture pranks, said he bought the ball and arranged to let the public decide its future online as a way to hold a conversation about a classic American sport in the digital world.

“This is obviously something that struck a chord with fans,” Ecko said.

Bonds broke the home run record with a shot into the right-center field seats off Washington Nationals pitcher Mike Bacsik at San Francisco’s AT&T Park.

Matt Murphy, a 21-year-old student and construction supervisor from New York, emerged from a scuffle holding the ball. He said he decided to sell it because he couldn’t afford to pay the taxes required to keep it.
