Rules at Pinnacle.........ya know you should really look at this before ya bet ya know
TENNIS
Match Betting:
A tennis match begins when the first ball is served. Thereafter, if a player retires or is disqualified, match bets on the retiring or disqualified player lose, and match bets on his opponent win. If no ball is struck, all match bets are void.
Set Betting:
If a player retires or is disqualified at any point during a match, Set Betting wagers are void.
Delay or Suspension:
If the start of a match is delayed, or if play during a match is suspended, all pending bets stand, even if the delay causes a match to be started or resumed on a day later than the originally scheduled date.
Futures (Ante post) Betting:
All futures (Ante post) bets have action. Should a player withdraw before a tournament begins, bets on that player to win the tournament lose.
Change of Venue or Playing Surface:
If the venue or playing surface for a match is changed, the wagering odds for match bets will be adjusted. Match bets placed at the pre-adjustment odds are void. Futures or Ante post wagers will stand.
