Otherwise, this market will resolve to \"Luca Staeheli\".\nGames won will be counted across all sets played in the match. A set decided by a tiebreak will count as one game for the winner of that tiebreak, and a match tiebreak played in place of a final set will also count as one game for its winner.\nIf the match is canceled (not played at all), or is delayed beyond 14 days from the scheduled date without completion at 11:59 PM ET, this market will resolve 50-50.\nIf the match begins but is not completed due to retirement, default, or disqualification, this market will resolve 50-50, unless the outcome of this market has already been unconditionally determined by the completed portion of play. For example, if the match ends at a point where Sebastian Gorzny could no longer have finished 3.5 or more games ahead even by winning every remaining game, this market will resolve to \"Luca Staeheli\".\nIf the match ends in a walkover (player withdraws before the start and the other advances automatically), this market will resolve to 50-50.\nThe primary resolution source will be official information from the ATP Tour. A consensus of credible reporting may also be used.","image":"https://polymarket-upload.s3.us-east-2.amazonaws.com/atp-tour-b4390c4fb8.jpg","icon":"https://polymarket-upload.s3.us-east-2.amazonaws.com/atp-tour-b4390c4fb8.jpg","outcomes":["Sebastian Gorzny","Luca Staeheli"],"outcome_prices":[0.5,0.5],"probability":0.5,"spread":0.98,"active":true,"closed":false,"start_date":"2026-09-15T14:44:12Z","end_date":"2026-09-22T21:30:00Z","closed_time":null,"volume":0.0,"volume_24hr":0.0,"prob_24h_change":-0.0050000000000000044,"volume_24h_change":0.0,"normalized_vol_24hr":null,"normalized_volume":null,"liquidity":3.2598,"categories":["Sports"],"countries":[],"updated_at":"2026-09-15T23:24:31.875400Z","fetched_at":"2026-09-15T23:24:31.875400Z","added_at":"2026-09-15T14:46:38.154522Z","url":"https://polymarket.com/event/atp-staehel-gorzny-2026-09-15/atp-staehel-gorzny-2026-09-15-game-handicap-away-3pt5","event_title":"Tiburon: Luca Staeheli vs Sebastian Gorzny","chart_24h":[0.505,0.505,0.505,0.515,0.55,0.545,0.55,0.55,0.56,0.5]},{"source":"polymarket","id":"4577777","event_id":"1026585","slug":"atp-staehel-gorzny-2026-09-15-match-total-23pt5","question":"Staeheli vs. Gorzny: Match O/U 23.5","group_item_title":"Tiburon: Luca Staeheli vs Sebastian Gorzny Match O/U 23.5","description":"This market refers to the tennis match between Luca Staeheli and Sebastian Gorzny in the Tiburon, originally scheduled for September 15, 2026 at 5:30PM ET.\nThis market will resolve to \"Over\" if the total number of games completed equals or exceeds 24.
