Rule Number 32 through 35?
RULE 32
Changing Balls
In cases where balls are to be changed after a specified number of games, if the balls are not changed in the correct sequence, the mistake shall be corrected when the player, or pair in the case of doubles, who should have served with new balls is next due to serve. Thereafter the balls shall be changed so that the number of games between changes shall be that originally agreed.
The Doubles Game
RULE 33
The above Rules shall apply to the Doubles Game except as below.
RULE 34
The Doubles Court
For the Doubles Game, the Court shall be 36 feet (10.97m.) in width, i.e. 4.5 feet (1.37m.) wider on each side than the Court for the Singles Game, and those portions of the singles side-lines which lie between the two service-lines shall be called the service side-lines. In other respects, the Court shall be similar to that described in Rule 1, but the portions of the singles side-lines between the base-line and service-line on each side of the net may be omitted if desired.
[USTA Comment: The Server has the right in doubles to stand anywhere back of the baseline between the center mark imaginary extension and the doubles sideline imaginary extension.]
RULE 35
Order of Service in Doubles
The order of serving shall be decided at the beginning of each set as follows:
The pair who have to serve in the first game of each set shall decide which partner shall do so and the opposing pair shall decide similarly for the second game. The partner of the player who served in the first game shall serve in the third; the partner of the player who served in the second game shall serve in the fourth, and so on in the same order in all the subsequent games of a set.
Case 1. In doubles one player does not appear in time to play, and his partner claims to be allowed to play single-handed against the opposing players. May he do so?
