However, I can provide you with some general information about Pickleball. Pickleball is a relatively new sport that was invented in 1965 by Joel Pritchard, Bill Bell, and Barney McCallum on Bainbridge Island, Washington, USA. It is a paddle sport that combines elements of tennis, badminton, and table tennis. The game is played on a badminton-sized court with a slightly modified tennis net, using solid paddles made of wood or composite materials to hit a perforated plastic ball.

Pickleball has gained popularity in recent years, especially among older adults, as it is a low-impact sport that provides a good workout and social interaction. The sport has its own governing body, the USA Pickleball Association (USAPA), which organizes tournaments and promotes the growth of the sport.

As for any significant events or milestones that may occur on July 12 in the future, we'll have to wait and see what the world of Pickleball has in store!
