X. EXHIBITS X. EXHIBITS The event organizers must announce in advance of the event:  a. The number of balls for play (2, 3, 4 or 6). b. The ball change policy, if any. Case 5:  Is a player allowed to use more than one racket at any time  during play? Decision:  No. Case 6:  Can a battery that affects playing characteristics be incor - porated into a racket? Decision:  No. A battery is prohibited because it is an energy  source, as are solar cells and other similar devices. Ball changes, if any, can be made either: i)  After an agreed odd number of games, in which case, the first ball change  in the match shall take place two games earlier than for the rest of the  match, to make allowance for the warm-up. A tie-break game counts as  one game for the ball change. A ball change shall not take place at the  beginning of a tie-break game. In this case, the ball change shall be de - layed until the beginning of the second game of the next set; or ii.  At the beginning of a set  If a ball gets broken during play, the point shall be replayed.  Case 1:  If a ball is soft at the end of a point, should the point be  replayed? Decision:  If the ball is soft, not broken, the point shall not be  replayed. Note:  Any ball to be used in a tournament which is played under the Rules of Tennis,  must be named on the official ITF list of approved balls issued by the International  Tennis Federation. 4. THE RACKET Rackets, which are approved for play under the Rules of Tennis, must comply with  the specifications in Appendix II. The International Tennis Federation shall rule on the question of whether any racket  or prototype complies with Appendix II or is otherwise approved, or not approved, for  play. Such ruling may be undertaken on its own initiative, or upon application by any  party with a bona fide interest therein, including any player, equipment manufacturer  or National Association or members thereof. Such rulings and applications shall be  made in accordance with the applicable Review and Hearing Procedures of the Inter - national Tennis Federation (see Appendix X). Case 1:  Is more than one set of strings allowed on the hitting sur- face of a racket? Decision:  No. The rule mentions a pattern (not patterns) of crossed  strings. (See Appendix II) Case 2:  Is the stringing pattern of a racket considered to be gener- ally uniform and flat if the strings are on more than one plane? Decision:  No. Case 3:  Can vibration damping devices be placed on the strings of  a racket? If so, where can they be placed? Decision:  Yes, but these devices may only be placed outside the  pattern of the crossed strings. Case 4:  During a point, a player accidentally breaks the strings. Can  the player continue to play another point with this racket? Decision:  Yes, except where specifically prohibited by event orga - nizers. 264 265 There are different methods of scoring in a set. The two main methods are the “Ad - vantage Set” and the “Tie-break Set”. Either method may be used provided that the  one to be used is announced in advance of the event. If the “Tie-break Set” method is  6. SCORE IN A SET Additional approved alternative scoring methods can be found in Appendix V. The player/team whose turn it was to serve first in the tie-break game shall be the  receiver in the first game of the following set. The player whose turn it is to serve shall serve the first point of the tie-break game.  The following two points shall be served by the opponent(s) (in doubles, the player of  the opposing team due to serve next). After this, each player/team shall serve alter - nately for two consecutive points until the end of the tie-break game (in doubles, the  rotation of service within each team shall continue in the same order as during that  set). During a tie-break game, points are scored “Zero”,“1”, “2”, “3”, etc. The first player/ team to win seven points wins the “Game” and “Set”, provided there is a margin of  two points over the opponent(s). If necessary, the tie-break game shall continue until  this margin is achieved. except that if each player/team has won three points, the score is “Deuce”. After  “Deuce”, the score is “Advantage” for the player/team who wins the next point. If that  same player/team also wins the next point, that player/team wins the “Game”; if the  opposing player/team wins the next point, the score is again “Deuce”. A player/team  needs to win two consecutive points immediately after “Deuce” to win the “Game”. A standard game is scored as follows with the server’s score being called first:  No point -   “Love” First point  -   “15” Second point  -   “30” Third point -   “40” Fourth point  -   “Game” 5.
