I was playing a pony league baseball game (13 YO) and had played P/C/SS for many years without a 'cup' on. I was slated to start behind the dish this game and when the umpire introduced himself he asked if I had a jock strap on. I said no and he smacked me in the nuts. I drop to the ground and my coach goes crazy. The old guy ump tells a story about how he lost a nut while playing baseball without one.
Rather idiotic way to check a 13 for one, I'd say...
Anyhow, I did not own one and after a few minutes the ump says he will not umpire unless both the P and C from each team wear one. We scrounge around and thankfully we find 2 jocks from teammates or older siblings that we can use. My 3 innings of catching were ok, but then I had to pitch and he would not let me pitch without one. I couldn't throw with the same motion and it was awful, same with the other pitchers. The final score was like 23-19 with about 30 walks and both teams were two of the better pitching staffs in the league. Thankfully both team's coaches protested and the game was wiped out and he did not umpire again.
