2025 WORLD CHAMPIONSHIP
TOURNAMENT
October 3rd - 5th
WellSpan Park | York, PA
The Tradition
Continues
2025 marks the 36th anniversary of the first Fast Pitch National Wiffle®Ball Championship, which was held in Boston, Massachusetts in August of 1989. In 2022 — United Wiffle®Ball’s 3rd year of organizing the National Championship — the tournament expanded globally for the first time with the inclusion of the Samurai Tigers from Saitama, Japan. Now officially a World Championship for the third year, the 2025 version of the tournament is the 32nd overall Championship.
The legacy of competitive Wiffle®Ball is rich, layered, and ever evolving. The players of past generations have paved the way for today’s crop, which is considered by most to be the deepest and most competitive in the sport’s history. And there is more to come. This year’s iteration of the Championship promises to be deep in young talent, including teams that have graduated and aged out of the landmark MLW U17 National Championship.
United Wiffle®Ball is proud to feed off the traditions established by multiple predecessor organizers in establishing a season-long component to and eligibility requirements for the Championship. At the same time, we recognize the desire to provide flexibility for October rosters and as a result, United Wiffle®Ball is continuing with the “3-player core” concept in 2025 that was first established in 2022. Please see below for additional information about the eligibility criteria.
The World Championship has hosted layers from 29 of the 50 U.S. states over the past 5 years and expects to add to that number in 2025. Competitive Wiffle®Ball has always been at its best when it includes talent from all over the country. Among the crowning achievements of that first Championship Tournament back in 1989 was its inclusion of teams from as far away from Massachusetts as California. UWIFF has been proud to carry on that tradition, not only by attracting teams all across the United States, but also globally. Please see below for logistical details on the tournament.
Wiffle®Ball is a a niche sport with a long and proud history. Competing in a UWIFF World Championship is more than a weekend activity. It is a chance to become part of a deep and rich history spanning almost 40 years. We hope that you will join us this October.
ABOUT
Where: WellSpan Park (5 Brooks Robinson Way, York, PA)
When: Saturday October 4th, 2025 and Sunday October 5th, 2025 (Friday FanFest on October 3rd)
Who: 32-40 competitive fast pitch Wiffle®Ball teams (4-5 player teams). Every team must meet the eligibility criteria described in detail below.
Registration Process: To register, teams must meet and be able to provide proof of meeting the eligibility criteria as described below. Teams must have 4 players when registering. Any entries with “TBA” or other filler positions will be rejected. Changes to a team’s roster after an approved registration are subject to UWIFF committee approval.
In order to ensure the highest quality format possible given the expected interest, the tournament will either be a 32-team of 40-team event. Only the first 32 teams to register and meet the eligibility/registration criteria will be guaranteed a spot in the tournament. After 32 teams have registered, an 8-team waitlist will open. Once the waitlist has filled up and the 8 teams have completed their final registration, registration will close. In the event that 8 teams are not on the waitlist by September 1st, the tournament field will revert to 32 teams and those on the waitlist will be issued a refund. We fully expect to reach 40 teams. However, the waitlist is necessary as a precaution to ensure a high-level tournament format.
Eligibility Criteria
United Wiffle®Ball prides itself as being not just a standalone tournament, but the culmination of the annual Wiffle®Ball calendar. To preserve the integrity of the tournament as a World Championship and the biggest prize in the sport, teams must become eligible through a simple & broad eligibility process. Any teams that have become met the eligibility requirements or will meet the eligibility requirements before the tournament are eligible to register when registration opens.
Eligibility steps:
(1) Enter a team in a league OR a standalone tournament;
(2) Compete in the league OR standalone tournament with 3-5 of the players on your planned World Championship Team;
(3) When registration for the World Championship Tournament opens, register your team, including providing information on what tournament or league was used for eligibility (if more than one, you only need to list one) and which 3 (or more) players on your World Championship roster competed in that tournament or league together.
It is that simple!
The style of play in the tournament or league used for eligibility does not matter - slow pitch, medium pitch, clean balls, base running, etc., they are all included as part of UWIFF’s mission to be as inclusive as possible. All that matters is that the tournament or league is a legitimate tournament or legitimate league with legitimate gameplay. In other words, do not attempt to fake a tournament or league to use for eligibility purposes. UWIFF will review all registration applications and confirm the legitimacy of every event.
If a team uses 3 players to become eligible, that team can add two additional players to those 3 “core players” for their UWIFF roster. This allows the best of both worlds - ensures that teams competing for the World Championship are established teams, while also allowing some element of free agency for the World Championship. If a team uses 3 players to become eligible and one of those 3 core players later becomes injured or unable to compete at the World Championship, that team is still eligible however they cannot replace that player on their roster and must compete with 4 players (with the unavailable player as the team’s rostered 5th player/3rd core player).
** International Team Exemption: International teams (any teams compromised of 3 or more players residing outside of the United States) are eligible to register without meeting the above criteria.
*** As in prior years, the top 4 finishers from the prior year WCT/NCT receive an automatic bid (upon payment of the standard entry fee and provided they return 3 of their 5 prior year WCT players) and do not have to meet the rest of the above criteria to be eligible to register. For 2024, these four teams are: Usual Suspects, Juggernauts, Phenoms, and Wiff Inc.
