What does baseball and softball have in common?

Answer 1

They have almost everything in common. The only differences are:

A softball is bigger, but it isn't as hard as a Baseball.

Softball games are usually six or seven innings.

Unlike the American League in pro baseball, there are no designated hitters in softball.

Answer 2

The basic rules of the game. 3 strikes, 4 ball, same positions, same ways to get out. But that pretty much is it.
