Baseball

Baseball is an Earth bat-and-ball game played between two teams of nine players each who take turns batting and fielding.

The offense attempts to score runs by hitting a ball that is thrown by the pitcher with a bat swung by the batter, then running counter-clockwise around a series of four bases: first, second, third, and home plate. A run is scored when a player advances around the bases and returns to home plate.

As humanity colonized other planets, some colonies began developing their own baseball leagues.
