I've seen the baseball diamonds near my house used exactly twice. Once involved using it for fireworks. It was built around the time of the 1964 olympics like nearly every baseball diamond in the country.
When a bat is going to cost you $300 and a full uniform and gear to play on a team is close to a $1000, there isn't much demand. The Melbourne girls baseball teams positions are more about forfeits than wins.
I don't know why the local baseball teams need such formal rules with such official imported uniforms. What ever happened to wearing a shirt the right colour?
