Editorial policy
How we write, check and correct what we publish.
Who writes LineupMeter
All content is published by the LineupMeter team. We do not use individual bylines. The team as a whole is responsible for every page, and questions or complaints go to the same contact address.
Projections are estimates
Projected lineups, start probabilities, batting orders and probable pitchers are our own estimates, produced by the method described on our methodology page. We label them as projections and keep them visually distinct from confirmed lineups. We never present an estimate as official information, and we do not publish invented lineups when we have no basis for a projection.
Facts and sources
- Factual statements in guides are checked against primary sources where possible, such as the Official Baseball Rules or the collective bargaining agreement between the clubs and the players' union. We name the source in the text.
- Figures we calculate ourselves are labelled as our own calculations, with the data source and season.
- We do not invent statistics or quotes. If we cannot verify something, we leave it out or say clearly that it is unverified.
- Lineup news will be logged with the time it was recorded and the type of source it came from.
How pages are produced
New pages and new page templates are reviewed before they are published. Routine data updates inside templates that have already been approved, such as a new day's projections, are published automatically after automated checks. Those checks stop a build if, for example, a required notice is missing.
Content on LineupMeter is produced with the help of AI tools and is reviewed before publication.
Advertising and independence
The site is funded by display ads only. Advertisers do not influence our projections or articles, and ads will be clearly separate from editorial content. We do not use affiliate links and do not accept payment for coverage.
Corrections
When we get a fact wrong in a guide or policy page, we fix it and add a dated note at the end of the page that says what changed. Projections are different: they are expected to be wrong some of the time, and they are graded in public under our accuracy policy rather than corrected after the fact.
