This section provides context and methodology details for the data presented:
- **Data Scope:** This table focuses exclusively on competitive results where a Male athlete participated in an event or competition originally intended for female athletes. This applies to events specifically labeled "female", "women" or "girls" or events that were originally female-only but have been changed to mixed sex to be "inclusive" of some men, but continue to exclude other men who do not claim to be women. This includes events labeled "women+" or similar. Events that are mixed but in which there are specific limits on the number of male and female athletes per team and in which the male athlete has taken a "female" position, such as mixed doubles in tennis, are also included.
- **Link Verification:** The provided links are to external sources. These sources include official results directly from the event webpages, sites that aggregrate athletic results from various organizations (such as MileSplit.com), news stories, and social media posts from team and athlete accounts. Archived links (Ar.) are provided in the case that these results are removed or websites are no longer functional. Not all pages were able to be archived. When possible, archived links can most often be found in the second (2) link.
- **Athlete Verification:** Athletes have been verified as male through the use of public sources: news articles, personal declarations from the athletes, name changes, past photos, and other public records including job history, school records, and family records. In the case of males with DSDs, athletes are included if they have previously failed a sex/gender test.
- **Athlete Identification:** "DSD" refers to male athletes with a disorder of sexual development. These athletes are male but may have been mistaken for female at birth due to underdeveloped male genitalia. "Trans-identified" refers to male athletes who have had healthy male development but deny that they are men and boys and claim to be something else, typically "women" or "nonbinary". "Other" refers to males who do not belong in either of the former categories but participate on female teams due to rule exceptions.
- **Sorting:** The table is sorted by **Date (newest first)** by default.
Other Notes:
- Per the USSSA rulebook, all co-ed teams must have 5 male and 5 female players on the roster at all times. As male athletes Thomas "Tracy" Nadzieja, Jason "Jamie" Neal, and "Brittney" Miller played in USSSA sanctioned tournaments, their co-ed or "mixed" results are represented here.
- USSSA sponsors multiple "National Championship" or "World Series" tournaments held around the country. These are classified as "Regional Championships" here as they do not represent an overall national champion.
- Thomas "Tracy" Nadzieja did not play in every tournament his teams were entered in. Only the tournaments he played are represented here and on the team record page. These tournaments were taken from his game log on the USSSA website.
- Male athlete "Brittney" Miller has played on women's teams outside of USSSA tournaments. Results for these teams are not known at this time.
- A male athlete identified by the initials A.M. has reportedly played on the girl's softball team at his school. Further information is unavailable at this time.
- An unidentified male athlete has reportedly played on the girl's softball team in the Madison, Wisconsin area. Further information is unavailable at this time.
- Dugan "Ellie" Knapp has reportedly played on the girl's softball team at his school in Ellison Bay, Wisconsin. Results are unavailable at this time.
