About Us
Last updated: 9 junio 2026
mlb Betting Systems is an independent editorial publication that covers Major League Baseball betting for a United Kingdom audience. We are not a sportsbook, an affiliate hub or a tipping service. We publish long-form analysis intended to help adult readers in the UK understand how MLB markets work, how the UK Gambling Commission regulates them, and how to evaluate strategies on a sound mathematical basis.
Our purpose
The English-language MLB betting literature is overwhelmingly written for a North American reader. Our purpose is to fill the gap: produce a thoroughly UK-focused body of work that uses sterling, decimal odds, GMT and British spelling; that takes UKGC regulation seriously rather than treating it as a footnote; and that grounds every claim in primary data wherever primary data exists.
Editorial responsibility
Every page on this site is written, reviewed and approved by the mlb Betting Systems editorial team. We do not use freelance contributors who write under a fixed name without our oversight, and we do not publish ghost-written content sourced from third-party content marketplaces. The organisation as a whole is the author of record for every article; this is reflected in our structured data, where the publisher and the author are the same legal entity.
How our content is created
Every published article passes through four stages before it is allowed to go live.
- Stage 1 — Topic scoping. A working brief is drawn up. It identifies the search intent we are addressing, the audience knowledge level, the primary data we will rely on, and any UK-specific regulatory points that must be covered. Topics that cannot be supported with primary data are not commissioned.
- Stage 2 — Drafting. An editor with a documented background in either professional sports analytics or financial-markets writing produces the first draft. All statistics carry an internal source citation pointing to the originating dataset.
- Stage 3 — Fact-check and compliance review. A second editor verifies every numerical claim against the primary source. They also check that the article complies with UK Committee of Advertising Practice (CAP) rules and the UK Gambling Commission’s licence conditions for non-licensee gambling content, including the requirement that risk be clearly communicated.
- Stage 4 — Publication and review. The article is published. Each piece carries a «last updated» date in its visible header and in its structured data. Articles in fast-moving topic areas — regulation, odds market structure, MLB rule changes — are reviewed at least every 90 days.
Sources we use
We work from primary sources wherever they exist and we are transparent about secondary sources where they do not. The most frequently cited primary sources in our work are listed below.
- UK Gambling Commission — annual industry statistics, quarterly market overview, consultations, licence-conditions documents, CEO speeches.
- Major League Baseball — MLB.com season releases, official attendance and viewership figures, the London Series economic-impact reports commissioned from Two Circles.
- Statcast and Baseball Savant — pitcher run-value, batted-ball metrics, park-factor breakdowns, weather-applied metrics.
- FanGraphs and Baseball-Reference — pitcher and team statistics, historical splits, advanced metrics such as FIP, xFIP, K-BB%.
- Two Circles — independent sports-business research, used for UK MLB economic-impact figures.
- Academic publications — peer-reviewed work on baseball physics (Dr. Alan Nathan), sports-betting market efficiency, and gambling-harm research published by the National Centre for Social Research (NatCen) and the University of Glasgow.
How we verify statistics
For every numerical claim, the responsible editor records the originating URL, the date the figure was checked, and the version of the dataset. Where a UKGC quarterly statistic is updated, our piece is updated within seven working days. Where a primary source is not available, we say so plainly in the article and explain why we have chosen a particular secondary source.
Corrections
If we publish a material error, we correct it. The corrected article carries a note describing what changed, when it changed, and why. Minor typographical fixes are made silently. We do not delete articles to hide editorial mistakes.
Independence and conflicts of interest
mlb Betting Systems does not currently accept paid affiliate links, paid placement of operator names, or sponsored content. If that policy changes, every commercial relationship will be disclosed in plain text on the page where the relationship is acted upon, and structured data will be marked accordingly.

Every article on this site is intended for adults aged 18 or over in the United Kingdom. Gambling carries real financial risk. Our content is educational only and is never a recommendation to wager.
