An evening baseball contest will take place between two professional teams, with the start time set for the specified date. The game's outcome will depend on whether it extends beyond the standard nine innings, potentially requiring additional playing time to determine a final result. This extension occurs only if the teams are tied after the initial regulation period.
If at least 1 extra inning is played in the Seattle vs Boston professional baseball game originally scheduled for Sep 1, 2026 at 6:45 PM EDT, then the market resolves to Yes.

In the coming weeks, key signals like starting pitcher announcements, weather outlooks, and team injury reports could shift this market. Any indication that fatigue or strategic decisions might lead to a prolonged contest will raise probabilities.
