This is the last of the awkward questions from the local quiz I am trying to complete. Have just browsed through loads of sets of rules and they all seem surprisingly vague on this point. Is there a Wimbledon Umpire out there somewhere, who will help please? Thanks
I thought jane mark 2 was correct but she has it the wrong way round - the first change of balls comes after SEVEN games with each subsequent change after every NINE games.
