Thingy,
I dont think that anyone ever replied to your inquisitions...
It takes 6 games to win a set. However if the opponent wins 5 games before you win six, you have to win by 2. Thus, you would have to win 7-5. In all tennis except Davis Cup and Grand Slams, if the score of a set is 6-6, then you go to a tiebreaker. Each point counts as one point (this is the parenthesis beside the scores). The first one to 7 points in the tiebreaker wins the set.
Jessica lost the tiebreaker in the 3rd set 7-2 tonight.
