Description

This market focuses on determining which team will score more runs specifically during the bottom of the 9th inning of an upcoming baseball game between Boston and Tampa Bay. It captures the excitement of late-game strategies and performance under pressure, isolating the final inning's outcome from the rest of the match.

Kalshi

The market resolves based solely on runs scored during the 9th inning of the designated Boston vs Tampa Bay game. If Boston scores more runs in that inning, the 'Boston wins 9th inning' market resolves to Yes. If Tampa Bay scores more runs, the 'Tampa Bay wins 9th inning' market resolves to Yes. If both teams score the same number of runs, the 'Tie 9th inning' market resolves to Yes. Should the game be called before the 9th inning is fully completed, all markets resolve to a Fair Price. The resolution depends exclusively on 9th inning performance, regardless of whether the home team bats in the bottom of the inning, unless the inning is incomplete due to an early game cancellation.
