The owners of professional baseball clubs approved a plan Wednesday to hold interleague regular-season games next year for the fist time ever.

The owners gave the go-ahead to the interleague game plan worked out by Nippon Professional Baseball officials earlier this week, in which each team will play 36 games during the 2005 regular season assuming that each league continues to have six teams.

Each Central and Pacific league team will play six games against each team in the other league. The number of interleague games will be reviewed on the basis of next year's results.
