Nippon Professional Baseball Commissioner Ryozo Kato will visit his major league counterpart Bud Selig next month to discuss a proposed club championship between the two sides, baseball sources said Friday.

The former ambassador to the United States is scheduled to meet with Selig when the 2010 All-Star Game is held at Angel Stadium on July 13.

Selig had been invited to the two-game NPB All-Star series in late July, but he has decided to attend the National Baseball Hall of Fame induction around that time.
