The World Baseball Classic champions are in Japan and now the World Series winners are coming, too.

For the first time, the reigning World Series champions will play in Japan when the Boston Red Sox meet the Oakland Athletics in the Ricoh Japan Opening Series 2008 on March 25 and 26 at Tokyo Dome.

Boston President and CEO Larry Lucchino, Oakland manager Bob Geren and MLB Players Association COO Eugene Orza were among the MLB and Japanese officials on hand at a news conference Tuesday at a Tokyo hotel to promote the event.
