About RunLine Lab
RunLine Lab is an independent editorial publication covering Major League Baseball betting from a United Kingdom perspective. The site is written and maintained for British punters who want a data-led view of MLB markets, UKGC-regulated operator coverage and the practical mechanics of betting on baseball from a different time zone. It does not run a sportsbook, take stakes, or operate any betting product itself.
This page sets out how the site is produced — the sources used, the verification steps applied, and the editorial standards that hold the coverage to account.
Who writes the site
RunLine Lab is published by its editorial team rather than by any single named author. Coverage is produced collectively by editors and contributors who have analysed MLB markets across UK sportsbooks for several years. The team includes contributors with a background in sports modelling, regulatory analysis, and writing about gambling for general audiences. The site does not publish staff biographies because individual identification is not necessary to verify the work — the methodology and the sources below are what readers can check against.
Editorial decisions are taken by the team as an organisation. There is no advertorial influence over which markets, operators or events are covered. Where an article references a UKGC-licensed bookmaker, it is because that operator carries MLB markets relevant to the topic, not because of any commercial arrangement.
Editorial methodology
Every article on the site is built around a structured research and verification process. The process is the same whether the piece is a 6,000-word pillar guide or a short market explainer.
The first step is to define the question the reader is bringing to the page. Pages are organised around real reader intents — for example, whether a market is legal in the UK, how a run-line price converts between odds formats, or whether bookmaker stream rights cover a fixture — rather than around keywords in isolation.
The second step is source assembly. Every factual claim in an article is mapped to at least one primary or authoritative source before drafting begins. We prioritise official publications and regulators over secondary commentary, and we prefer recent material over older material where the regulatory or market position has shifted.
The third step is drafting, which is done by a contributor briefed against the source map. Drafts include inline references to the sources used so that editors can re-check each claim against the original document.
The fourth step is editorial review. An editor reads the draft against the source map, flags any claim without a direct source, and removes or rewrites any passage that depends on assumption rather than evidence. Statements about UK gambling regulation are checked specifically against UKGC publications. Statements about Major League Baseball as an organisation, season structure, or rule changes are checked against the official MLB.com site or league press releases. Statements about bookmaker coverage are checked against the operator’s own published terms or product pages.
The fifth step is publication and dating. Each piece carries a publication date and is reviewed for accuracy on a rolling schedule. Where source material has been updated by the issuing body, the page is updated to reflect the change and the modification date is refreshed.
Sources we use
The site draws on a defined set of authoritative public sources rather than on user-generated forums, paid databases or syndicated wire content. The main categories are listed below so that readers can verify any claim against the same source we used.
For UK regulatory matters, we use the UK Gambling Commission as the primary source, including its public register of licensed operators, its published Licence Conditions and Codes of Practice, and its annual statistical bulletins. For Government policy on gambling, we draw on the Department for Culture, Media and Sport, HM Treasury publications, and Hansard transcripts where directly relevant.
For Major League Baseball as a competition, we use MLB.com, the league’s official press releases, and the formal rules of baseball as published by the league. For statistical context, we draw on official MLB league statistics and openly published season summaries.
For UK problem-gambling support, we link to GamCare, BeGambleAware, GAMSTOP, and the NHS gambling addiction support pages, all in their official capacity rather than via aggregators.
For UK betting industry context, we draw on the Betting and Gaming Council’s published statements and on publicly issued statements from individual UKGC-licensed operators. Where we cite figures, we cite them with the issuing body and the period they refer to.
How we verify data
Numerical claims are the area where small errors compound quickly, so the site applies a tighter check to every figure published. Each statistic in an article must be traceable to a named source with a date. Where two reputable sources differ, the article either uses the source that publishes its methodology in the open, or it presents both figures with the difference explained.
We do not publish operator ratings, scored leaderboards, or comparison tables that imply one bookmaker is better than another. Reasoning: such ratings are inherently subjective, depend on the reader’s individual usage pattern, and are easy to misuse as a recommendation. Where the site references specific UKGC-licensed operators, it does so to describe coverage depth in the market context — not to recommend an account opening.
Pricing examples used in articles are illustrative. A price quoted at decimal 1.91 is used to show how decimal, fractional and American odds map to each other and how payout arithmetic works. It is not a live price, and the site does not present any market price as a real-time recommendation.
What this site is not
RunLine Lab is editorial, not advisory. The content on the site is not financial advice, legal advice, tax advice, or a betting tipster service. The site does not offer accumulator coupons, daily picks, or stake suggestions. The editorial team is not authorised to provide advice on individual circumstances and does not do so.
The site is not a UKGC-licensed operator and does not accept stakes or hold customer funds. The bookmakers referenced in articles are independent businesses; their licensing, terms of service, and product offering are their own responsibility and are subject to change at any time.
Corrections and feedback
If a claim on the site is wrong, we want to know. The site publishes a stable contact route through the domain mlb Online Betting. Email corrections to the editor’s address listed there. Where a correction is verified, the page is updated and the modification date is refreshed. Where a correction is significant — a changed figure, a reversed regulatory position, or a corrected interpretation — the correction is noted at the foot of the article so that readers can see what changed.
Reader feedback that is not a correction — suggestions for new topics, requests for deeper coverage of a market, or questions about an explainer — is welcomed at the same address. We do not provide individual betting advice in reply, but we do use the patterns in reader questions to shape what we cover next.
Responsible gambling
Every article on the site is written with the assumption that the reader is an adult resident of the UK who is choosing to bet within the regulated UKGC framework. Where an article references a market or a tactic, it does so within that frame. Gambling is high-risk by definition; the site does not soften that fact. Readers who recognise warning signs in their own behaviour — chasing losses, betting beyond what is affordable, or feeling unable to stop — are encouraged to use GAMSTOP for cross-operator self-exclusion and to seek free, confidential support from GamCare or BeGambleAware. Anyone under 18 should not be on this site or any UKGC-licensed sportsbook.
