My father never coached me. I always had someone else's dad. I got virtually no instruction. I still remember being a catcher and our pitcher (coach's son) started throwing curve balls at some point (age 11/12??) and I had to guess at what that wobbly thing was. Finally the umpire told me.
We didn't call pitches, I never knew it was coming...whenever it did.
I learned most things from listening to my dad at home, and watching the Big Red Machine and trying to imitate what they did. I was a pretty good player - and later a very good mens softball league player. Oh what coulda been if I'd just had some coaching!
