The focus is on whether both teams can produce at least two runs collectively in the eighth inning. This threshold adds a higher bar compared to scoring just one run.
Markets resolve to Yes if the Oakland Athletics and Tampa Bay collectively score more than 1.5 runs in the 8th inning of their professional baseball game scheduled for September 15, 2026. Only runs scored during the 8th inning count; if the game is called early before the inning completes, the market resolves to a Fair Price.
