The first segment of a professional tennis match between two athletes determines an immediate result, reflecting early momentum and strategy in a competitive encounter.
The market resolves based on which player wins the first set in the James Duckworth vs Mariano Navone professional tennis match at the 2026 ATP Winston Salem Round Of 32. If the match does not occur due to injury, walkover, forfeiture, or cancellation before play begins, the market resolves to a fair price. Postponements or delays keep the market open until the rescheduled match concludes. In case of retirement during the match, markets can resolve based on completed play; otherwise, unresolved markets settle at Fair Market Price determined by the Exchange.
