How this market resolves
This market will resolve to "Yes" if the greatest number of innings played in any single game of the 2026 MLB Postseason equals or exceeds the listed number. Otherwise, this market will resolve to "No".
A game counts at the number of innings in which play occurred, as recorded by MLB in the official box score. A game that ends in the bottom of its final inning counts at that inning number, even though that inning was not completed. A suspended game that is later resumed and completed counts as a single game at its final inning total. A game that is shortened or called before completion counts at the last inning completed.
Only games in 2026 MLB Postseason games will count toward this market. The 2026 MLB Postseason comprises the Wild Card Series, the Division Series, the League Championship Series, and the World Series. Regular season games, exhibition games, and any tiebreaker or "Game 163" will not be considered part of the 2026 MLB Postseason.
If the 2026 MLB Postseason is cancelled, or the World Series has not concluded by November 15, 2026, 11:59 PM ET, this market will resolve to "No".
The resolution source for this market will be official information from MLB; however, a consensus of credible reporting may also be used.
