Description

This market focuses on determining which team will score more runs specifically in the 9th inning of an upcoming baseball game between the A's and Tampa Bay. It captures the excitement and strategic shifts that often occur in the final inning, where bullpens are tested and late-game decisions can dramatically influence the outcome.

Kalshi

The market resolves based solely on the number of runs scored by each team during the 9th inning of the specified game. If the game is called before the 9th inning is fully completed, it will resolve to a Fair Price. The resolution depends exclusively on 9th-inning performance, regardless of whether the home team gets to bat in the bottom of the inning, unless the inning is incomplete due to an early game cancellation. All outcomes—A's winning the 9th inning, Tampa Bay winning the 9th inning, or a tie—are determined by comparing runs scored in that specific inning only.
