Softball is directly descended from baseball and thus contains many similarities, however there are several pronounced differences. The primary reason for these differences is that softball was originally intended to be played indoors.
Most of the differences between fastpitch softball and slowpitch softball are designed to give batters more dominance and make offense more important.
