Atsunori Inaba already knows he'll be managing Samurai Japan during the 2020 Tokyo Olympics.
When it comes to Don Mattingly and Team USA, well, never say never.
Right now, the two managers are preparing to face off in the Japan All-Star Series which begins Friday and will see an MLB All-Star team managed by Mattingly, the current Miami Marlins skipper, take on Inaba's Samurai Japan team in a six-game series.
