# Mayot vs Cassone: the old game-spread contract needs more than a winner A September 26 game handicap remains open. Total games and any retirement exception are the relevant evidence. Canonical article: https://www.homeincomelab.com/stories/atp-mayot-cassone-2026-09-26 Publisher: The Outlook By: [The Outlook editorial desk](https://www.homeincomelab.com/editorial) Category: Sports Analysis as of: 2026-10-04T10:30:51.735578Z Decision guide market prices observed: 2026-10-04T09:57:48.323Z Published: 2026-10-04T10:30:51.735578Z ## Quick answer The Saint-Tropez event has ended: its official site identifies Titouan Droguet as the 2026 champion. A September 26 Mayot–Cassone game-spread contract nevertheless remains open at 50–50 in our October 4 data. It is an unresolved statistical contract, not an upcoming match preview. [1](https://polymarket.com/event/atp-mayot-cassone-2026-09-26)[2](https://www.saint-tropez-open.com/) ## Key takeaways - Mayot must finish at least two counted games ahead of Cassone to cover −1.5. The arithmetic adds games across sets, so winning the match is insufficient by itself. A narrow match win can fail this threshold, while some match losses can still leave a player ahead in total games. [1](https://polymarket.com/event/atp-mayot-cassone-2026-09-26) - The Mayot side is supported by a completed official score showing the required net margin. A hypothetical 6–4, 6–4 win creates a four-game advantage; that illustration explains the test and is not a reported score. - If play ended early, the retirement rule takes priority over casually counting the current margin. The contract normally splits 50–50 unless the outcome was already unavoidable under every possible lawful completion of the match.

A September 26 Mayot–Cassone game-spread contract nevertheless remains open at 50–50 in our October 4 data. It is an unresolved statistical contract, not an upcoming match preview. [1](https://polymarket.com/event/atp-mayot-cassone-2026-09-26)[2](https://www.saint-tropez-open.com/) For the exact contract “Game Spread: Harold Mayot (-1.5) vs Murphy Cassone (+1.5)”, our October 4 observation was Harold Mayot 50%; Murphy Cassone 50%. These are recorded contract prices, not an official result. The parent event’s cumulative volume was $466,607; that turnover includes other constituent contracts and is not the volume of this selection alone.

The arithmetic adds games across sets, so winning the match is insufficient by itself. A narrow match win can fail this threshold, while some match losses can still leave a player ahead in total games.

A hypothetical 6–4, 6–4 win creates a four-game advantage; that illustration explains the test and is not a reported score. If play ended early, the retirement rule takes priority over casually counting the current margin.

A set tiebreak contributes one game to its winner, and a match tiebreak replacing a final set also counts as one game. Pre-start walkovers and cancellations settle 50–50.

The 14-day completion window runs to October 10 at 11:59 p.m. ET; the existence of that fallback does not mean the tournament is still running.
