A couple decades ago I played third base on a fast-pitch softball team. In fast pitch there is a lot of bunting and the third baseman has to play in shallow, close to the batter. I was never mistaken for an all-star, but I still have all my teeth, so I consider myself a success at that position.
One season, we had on our club a recent college graduate, who was a pitcher on her college softball team. The “her’ became the problem. There was controversy and outrage and meetings about whether she should be allowed to play. Keep in in mind this was a purportedly adult league. As we were in the Portland City League and played on Portland city-park fields, she played. And guess what happened: nothing. The league survived and the sports world kept going as usual.
Well into the twenty-first century, you would think this is not an issue. You would be wrong. Soccer teams in Phoenix are trying to maintain the purity of the sport.

Postscript:
The Sonoma Stompers minor-league baseball team made news 
this summer with a woman on the pitcher’s mound. Earlier this year, the Stompers were the first team with an openly-gay player on the field.
The last time I played fast pitch softball was at a psych dept. picnic out in Battleground WA in the early 60’s. Don’t recall why but people were disappearing rapidly, probably to go eat, but the pitcher stuck around and decided to whiz one more past me to strike me out but I hit it a ton. Longest homer I ever hit, lost the ball out in the forested area and no one but the pitcher was left to see my moment of glory. I stuck to golf after that and really sucked at that game.
