This market measures the total runs scored by the Houston Astros and Tampa Bay Rays in the first inning of their scheduled contest. Only runs from that opening frame matter, and the market outcome is determined exclusively by whether the combined tally exceeds one run.
If Houston and Tampa Bay collectively score more than 1.5 runs in the 1st inning of the Houston vs Tampa Bay professional baseball game originally scheduled for Sep 11, 2026 at 7:10 PM EDT, then the market resolves to Yes.
