This set of markets tracks the performance of Boston and Tampa Bay in the first five innings of their scheduled baseball game. Each market focuses on different run differentials to determine the outcome. The markets remain active even if the game is postponed, closing only after the rescheduled match concludes.
These markets evaluate whether Boston or Tampa Bay achieves a specified run differential victory within the first five innings of their professionally scheduled game on September 18, 2026. Four distinct markets exist: Tampa Bay winning by more than 2.5 runs, Tampa Bay winning by more than 1.5 runs, Boston winning by more than 1.5 runs, and Boston winning by more than 2.5 runs, all measured strictly within the first five innings. If the originally scheduled game is postponed or delayed, all markets stay open and will close only after the rescheduled game’s completion, provided the reschedule occurs within two days of the original date. No affiliation or endorsement by the governing league is implied, and all trademarks remain property of their respective owners.
