Transparent Adjudicator's Statement
Summary of Claim
Atlas World Records received a claim that the slow pitch softball home run derby conducted on February 19, 2026 at Sportsman’s Park Field, Cactus Yards, Gilbert, Arizona constituted the Largest Slow Pitch Softball Home Run Derby (Number of Participants).
The event was organized by Spiderz Sports and restricted to registered participants of the 2026 Spring Training Mega Draft tournament. The derby began at 7:30 a.m. and concluded at 10:07 p.m. Over the course of the day, 267 unique competitors participated.
All participants competed under a unified rule structure. Each competitor received ten official swings and four takes. Advancement to the finals was determined from results accumulated across the entire day. While men’s and women’s divisions were recognized for competitive outcome purposes, both operated within a single structured derby event governed by identical rules, equipment standards, and scheduling.
The claim seeks recognition based on the total number of unique participants competing within that single structured event.
Evidence Submitted
Atlas received the official participant roster listing 267 unique names, along with individual log sheets documenting each competitor’s swings. On-site adjudicator logs confirm continuous oversight throughout the event’s duration.
Video documentation includes continuous timelapse coverage of the derby’s operation, as well as recorded confirmation of the rule briefing, fence dimensions, bat certification requirements (220/240 stamp), and ball specification (Worth Launch 650). Written confirmation from the organizer verifies that all participants competed under identical conditions and that no separate or concurrent derby structures existed.
The submitted materials demonstrate that each listed participant completed official swings within the same structured event window.
Comparative and Cross-Archive Benchmark Review
Atlas conducted a review of publicly documented slow-pitch softball home run derbies held at major tournament events, including USSSA Conference competitions, national showcase events, and high-profile prize derbies conducted at tournament weekends.
Publicly available documentation typically reflects participation counts ranging from several dozen to approximately one hundred to one hundred fifty competitors. No independently verified record was identified documenting 267 unique participants competing within a single continuous slow pitch softball derby governed by uniform rules and conducted as one structured event.
The participation total under review materially exceeds documented participation levels in comparable competitions.
Verification Methodology
Atlas evaluated the claim by confirming that the derby operated as one unified event governed by a consistent rule set, that participation was restricted to a defined and documented pool of registered tournament players, and that each listed participant completed official swings under identical conditions.
The participant roster was reviewed for duplication and cross-referenced against swing logs to confirm active participation. Event structure was examined to ensure that men’s and women’s competitive brackets functioned as subdivisions of one overarching derby rather than separate independent competitions. On-site adjudication and contemporaneous documentation provided additional procedural verification.
No evidence of roster inflation, duplication, rule fragmentation, or structural separation was identified.
Adjudication Findings
Based on review of all submitted materials and on-site verification, Atlas finds that the event constituted a single structured slow-pitch softball home run derby featuring men’s and women’s divisions operating under one unified rule framework. A total of 267 unique competitors participated, each receiving ten official swings and four takes.
The event was conducted continuously within one defined timeframe and did not fragment into multiple independent competitions.
The claim satisfies the defined criteria for recognition as the Largest Slow-Pitch Softball Home Run Derby (Number of Participants).
Conclusion
Atlas World Records hereby certifies that on February 19, 2026, at Cactus Yards in Gilbert, Arizona, 267 unique participants competed in a single structured slow-pitch softball home run derby organized by Spiderz Sports.
This performance establishes a new world record in the category of Largest Slow-Pitch Softball Home Run Derby (Number of Participants).
