Like baseball, softball is derived from the English game of rounders. At the Olympics, it's a women only sport.
Softball shares many similarities with baseball. It's a nine-a-side game played on a grass diamond, with a batter attempting to hit pitches and get onto base.
The main differences are that the softball is larger than a baseball, and the game is played with a smaller bat. Unlike baseball, the pitcher throws the ball underarm.
It may be a women only sport at The Olympics, but back here softball is open to everyone.
