This event covers the professional tennis doubles semifinal match between Delgado/Falck and Almeida/Matta at the 2026 M15 Rochester NY tournament on July 18. The outcome depends on which team wins the match after play has begun.
The match must begin with a ball being played to be considered official. If the match does not occur before play starts due to injury, walkover, forfeiture, or cancellation, all markets resolve to $0.50. If any player on either team fails to participate in the match—even if replacements play and the match proceeds with some original players—the event is treated as a different match and resolves to $0.50. If a team withdraws or forfeits after the match has started, that team resolves to No. Matches that are postponed or delayed remain open and will close after the rescheduled match concludes, provided the reschedule occurs within two weeks of the original date.
