Game decided by replay review
“The final play was overturned on review. When does my bet settle?”
MLB's rulebook decides what happens to the game; it says nothing about wagers. What happens to a bet is set by each sportsbook's own house rules, and they genuinely differ from book to book. Check the house rules of the book where the wager was placed. Settlement timing is a house rule: books generally settle on the official final result as confirmed by their stats provider, including post-review rulings, but the confirmation standard is per-book.
Under MLB rules the outcome after review is simply the outcome — the final score is whatever stands once all reviews and umpire rulings are complete.
- Which official result does the book treat as final for settlement (league confirmation, stats provider)?
- How are obvious settlement errors corrected after a review-driven result change?
- Are live markets suspended during reviews, and how are they repriced?
