# Lehecka vs Vallejo: checking the result behind a 99.75% quote The Japan Open contract has an extreme price, but its actual test is qualifying advancement from this specific match. Canonical article: https://www.homeincomelab.com/stories/atp-lehecka-vallejo-2026-10-04 Publisher: The Outlook By: The Outlook editorial desk Category: Sports Analysis as of: 2026-10-04T10:46:25.198255Z Decision guide market prices observed: 2026-10-04T10:42:40.901Z Published: 2026-10-04T10:46:25.198255Z ## Quick answer Jiri Lehecka was quoted at 99.75% against Adolfo Vallejo’s 0.25% in the October 4, 10:42 UTC snapshot. The listed 4:30 a.m. ET start had already passed. This is an open-contract status explainer; it does not independently confirm a final Japan Open score.

[3](https://polymarket.com/event/atp-lehecka-vallejo-2026-10-04/atp-lehecka-vallejo-2026-10-04) - A retirement after play begins follows the advancing player. [3](https://polymarket.com/event/atp-lehecka-vallejo-2026-10-04/atp-lehecka-vallejo-2026-10-04) - A pre-start walkover instead produces a 50–50 settlement. [3](https://polymarket.com/event/atp-lehecka-vallejo-2026-10-04/atp-lehecka-vallejo-2026-10-04) ## An extreme quote after the scheduled start The remaining question concerns Jiri Lehecka against Adolfo Vallejo at the Japan Open Tennis Championships. At 10:42 UTC on October 4, the winner contract recorded Lehecka 99.75% and Vallejo 0.25%. Because the original start time had passed, it would be misleading to label this automatically as a fresh pre-match prediction. [1](https://polymarket.com/event/atp-lehecka-vallejo-2026-10-04)[3](https://polymarket.com/event/atp-lehecka-vallejo-2026-10-04/atp-lehecka-vallejo-2026-10-04) The parent event had $138,306 in cumulative turnover. That includes its constituent contracts and does not identify how much supports this one selection or whether traders are reacting to a live or finished match. [1](https://polymarket.com/event/atp-lehecka-vallejo-2026-10-04) ## The match winner is not every neighbouring contract The event also contains game-spread, set-handicap and total-games questions. Lehecka advancing would not by itself establish the answer to every one of them. A winner can prevail narrowly, while the separate handicap may require a particular margin. [1](https://polymarket.com/event/atp-lehecka-vallejo-2026-10-04) Tennis counts games within sets and sets within the match. That scoring hierarchy explains why a convincing set, an aggregate game advantage and actual advancement should not be treated as interchangeable outcomes. [2](https://www.itftennis.com/en/about-us/organisation/tennis-glossary/) ## What would establish each outcome The Lehecka side is supported by an official record showing his qualifying advancement. If Vallejo retires after play begins and Lehecka advances, the winner contract follows that result. [3](https://polymarket.com/event/atp-lehecka-vallejo-2026-10-04/atp-lehecka-vallejo-2026-10-04) Vallejo advancing would support the competing side. A withdrawal before play starts takes a different branch: the contract specifies 50–50, even if the draw shows one player advancing automatically. No current injury or withdrawal is asserted here. [3](https://polymarket.com/event/atp-lehecka-vallejo-2026-10-04/atp-lehecka-vallejo-2026-10-04) ## The official record and the fallback Official ATP information is the named primary settlement source, with credible reporting allowed as a secondary reference. The match identity, status and advancement record should be matched before declaring a winner. [3](https://polymarket.com/event/atp-lehecka-vallejo-2026-10-04/atp-lehecka-vallejo-2026-10-04) The original start was October 4 at 4:30 a.m. ET. If no winner is determined by October 18, 2026, 11:59 p.m. ET, or if cancellation or a tie applies, the contract splits 50–50. That later deadline does not mean the match is still in progress.

Source: [International Tennis Federation: tennis scoring glossary](https://www.itftennis.com/en/about-us/organisation/tennis-glossary/) ## Weighing the outcome ### Outcome in focus Jiri Lehecka advances against Adolfo Vallejo ### Supporting case A qualifying official Lehecka advancement supports this side, including an opponent retirement after play starts. [3](https://polymarket.com/event/atp-lehecka-vallejo-2026-10-04/atp-lehecka-vallejo-2026-10-04) ### Challenging case Vallejo advancing supports the opposite side; a pre-start walkover or listed fallback instead splits the contract.

[1](https://polymarket.com/event/atp-lehecka-vallejo-2026-10-04)[3](https://polymarket.com/event/atp-lehecka-vallejo-2026-10-04/atp-lehecka-vallejo-2026-10-04) ### Assessment Check the final match record before turning an extreme price into a reported result. ## How the market resolves The player who qualifies by advancing in this exact match wins. An in-match retirement, default or disqualification follows the advancing player; a pre-start walkover, cancellation or tie produces 50–50. [3](https://polymarket.com/event/atp-lehecka-vallejo-2026-10-04/atp-lehecka-vallejo-2026-10-04) ## Timing and deadline Original start: October 4, 2026, 4:30 a.m. ET. No winner by October 18, 2026, 11:59 p.m. ET means 50–50. [3](https://polymarket.com/event/atp-lehecka-vallejo-2026-10-04/atp-lehecka-vallejo-2026-10-04) ## Questions and answers ### Does 99.75% prove Lehecka has won? No. It is a dated quote; the official match result is a separate source record. [3](https://polymarket.com/event/atp-lehecka-vallejo-2026-10-04/atp-lehecka-vallejo-2026-10-04) ### Does a retirement void this winner contract? Not if play began and a player advances due to the opponent’s retirement. The advancing player wins this contract. [3](https://polymarket.com/event/atp-lehecka-vallejo-2026-10-04/atp-lehecka-vallejo-2026-10-04) ### What if the match never starts? A pre-start walkover or cancellation triggers 50–50 under the rules.
