An outcome is considered unconditionally determined if it would have been guaranteed under every possible completion of the match played according to the match format published by the tournament organizer for that round, including whether a final set is played as a full set or as a match tiebreak. For example, for a line of 21.5, if play stops at 6-3, 5-6, completing the match would have required at least 2 additional games, resulting in at least 22 games played, so \"Over\" would resolve as the winning outcome. Likewise, if the published format replaces the final set with a match tiebreak, that tiebreak counts as one (1) game, so for a line of 22.5, if play stops at 6-2, 3-3, the match could have reached at most 22 games and \"Under\" would resolve as the winning outcome.\nThe primary resolution source for this market will be official ATP Tour statistics; however, 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":["Over","Under"],"outcome_prices":[0.0,1.0],"probability":0.0,"spread":0.001,"active":false,"closed":true,"start_date":"2026-10-25T05:44:27Z","end_date":"2026-11-01T19:40:00Z","closed_time":"2026-10-26T00:06:04.117897Z","result":"Under","volume":0.0,"volume_24hr":0.0,"prob_24h_change":-0.49,"volume_24h_change":0.0,"normalized_vol_24hr":null,"normalized_volume":null,"liquidity":0.0,"categories":["Sports"],"countries":[],"updated_at":"2026-10-26T00:20:28.445869Z","fetched_at":"2026-10-26T00:20:28.445869Z","added_at":"2026-10-25T05:48:42.733964Z","url":"https://polymarket.com/event/atp-baris-heck-2026-10-25/atp-baris-heck-2026-10-25-match-total-23pt5","event_title":"Sioux Falls: Ozan Baris vs Hunter Heck","chart_24h":[0.49,0.5,0.495,0.5,0.0005,0.0]}]}
