I apologize for the confusion, but as an AI language model, I don't have access to real-time information or future events. The date you provided, 2025-04-26, is in the future from the current date, which is April 2023. Additionally, as Pickleball is a relatively new sport that has gained popularity in recent years, there may not be a significant historical event specifically tied to April 26th in Pickleball history.

However, I can provide you with some general information about Pickleball's history and its growing popularity:

Pickleball was invented in 1965 by three friends - Joel Pritchard, Bill Bell, and Barney McCallum - on Bainbridge Island, Washington. They created the game as a fun activity for their families, using ping-pong paddles, a wiffle ball, and a lowered badminton net.

The sport gained popularity throughout the 1970s and 1980s, particularly among seniors in retirement communities. In 1984, the United States Amateur Pickleball Association (USAPA) was formed to promote and govern the sport.

In recent years, Pickleball has experienced a surge in popularity, with an estimated 4.8 million players in the United States alone as of 2021. The sport has attracted players of all ages and skill levels, from casual enthusiasts to competitive athletes.

While I cannot provide a specific historical event for April 26th in Pickleball history, the sport continues to grow and evolve, with tournaments, clubs, and leagues popping up around the world. As Pickleball's popularity continues to rise, it's likely that we will see more significant milestones and events in the future.
