Tennis Wagering
Wagers have action once a ball is served, regardless of the date the match/event is started or completed. Matches delayed by rain, darkness, or other circumstances will not be voided. These matches will remain pending until their completion.
A "Walk Over Winner" (player concedes before a match) and matches which do not complete the first set are graded no action. Any match concluding after the first set is completed will be graded with the advancing player as the winner.
