Free agent catcher Kenji Jojima revealed Sunday he has formally signed a contract with U.S. sports management firm CSMG.

CSMG Chairman Alan Nero will take charge of negotiations with major league teams over Jojima, who declared free agency from the Softbank Hawks on Oct. 31.

New York Yankees left-hander Randy Johnson and St. Louis Cardinals outfielder So Taguchi are among CSMG's clients.

"I just got my agent. So I haven't heard anything concrete," Jojima said. Teams can start talks with the 29-year-old from Wednesday.

Jojima also mentioned the possibility that he will stay with the Hawks. "To declare free agency is usually taken as a move to some other team. But it only makes more options available to me," he said.
