THE COMPETITION the doubles event at the time he is called as a lucky loser/alternate in singles,  the singles match may be rescheduled so he can fill the lucky loser/alternate position, provided the Supervisor determines that the rescheduling does not  cause an unreasonable disruption of the schedule or does not cause the win - ner to play a second match that day; otherwise the next available lucky loser/ alternate shall be selected to fill such vacancy. VII. THE COMPETITION forced to withdraw because of injury. No one signed the lucky loser  list on Monday. How is the vacancy resolved? Alternate Sign-In Procedures Case:  The two (2) players ahead on an alternate list do not sign in  1/2 hour before the singles qualifying matches are to begin. One (1)  of the players arrives on-site just before it is known that an alternate  is going to be needed. Who gets in? Decision:  Neither of the two (2) players. In order to be eligible for  substitution, an alternate must sign in before the deadline and must  be ready to play within five (5) minutes of being called.  Doubles Alternate at two tournaments? Case:  A team signs in for doubles at two tournaments the same  week. They do not get into the main draw, but are the #1 alternate  at both events. The team signs the Alternate list at tournament A  on Monday and Tuesday and then wants to sign the Alternate list at  tournament B on Wednesday. Are they permitted to do this? Decision:  Yes, however, a team is only eligible to be signed in on  one “live” list per day.  Eligible for Lucky Loser - ATP Tour Case:  May a player or team sign the lucky loser sign-in sheet if they  are not accepted into the qualifying competition?

Extending Closing Times Case:  The first-round singles matches are scheduled to start at 10  a.m. A steady rain is falling at 9 a.m. and it is decided to postpone  the start of play until 11 a.m. should the lucky loser sign-in be  extended? Decision:  Yes. Extend the deadline to 10:30 a.m.  Case:  The lucky loser Sign-in closed at 10:30. A player arrives at  10:45 to sign in saying that: 1.  The Referee told me that the deadline would be at 11:00; or 2.  Somebody on the phone said the deadline was 11:00; or 3.  Tournament transportation was 45 minutes late. Decision: 1.  Allow the player to sign in. Information given by the Referee (if  verified) must be honored. 2.  Sign-in not allowed.

The player is responsible for arriving on time.  Which Lucky Loser to Insert? Case:  On Monday before the last singles match has gone on court,  a player whose first-round singles match is scheduled for Tuesday is  144 145 Decision:  The vacancy should be filled from Monday’s lucky loser  list. However, since no one signed the lucky loser list on Monday,  the vacancy shall be filled from the Tuesday lucky loser list, if any  eligible players sign in. If no one signs on Tuesday, then a walkover  shall be awarded.  Who Goes In? Case:  A player withdraws from the singles event on Tuesday. His  singles match was not scheduled until Wednesday. There was  a singles lucky loser sign-in on Tuesday. The last singles match  scheduled for Tuesday has not gone on court. Is the vacancy filled  from Tuesday or Wednesday’s lucky loser sign-in? Decision:  Tuesday’s sign-in. C. Vacancies ATP Tour 1) A team shall constitute a doubles entry. If either of the players of a team cannot  play, that doubles entry is subject to withdrawal and substitution. 2)  If the withdrawal is from the advance acceptance list and prior to 12 Noon (EST) on the Friday before the event, then the next team on the alternate list is moved  into the main draw.  (See ATP Addendum, page 388) 3)  If the withdrawal is from the advance acceptance list and occurs after the 12 Noon  (EST) deadline on the Friday before the event then an additional on-site entry  position is created for each withdrawal.  a) For both 2 and 3 above, the partner of the withdrawing player may enter dou - bles or sign in for the singles qualifying of the same or another event through  the on-site entry method; or b)  If the withdrawal was due to one or both players being accepted into the main  draw singles of another ATP Tour or ATP Challenger Tour event, then both  players may enter the doubles of that event through the appropriate on-site  entry procedure. 4)  If a player from a team that is a direct acceptance withdraws based on a medical  reason or other unavoidable circumstances after the on-site sign-in deadline, his  partner may enter as an on-site alternate with another player who has not already  been accepted into the main draw doubles event. This new team may be consid - ered for acceptance based on its position in the on-site entry list including any  entry protection position, as specified in  7.20 A. 6) b) .  Can I Sign In For Q’s after Withdrawing from Doubles? Case:  A player is withdrawing from a Doubles Advanced Entry list  where he is a direct acceptance.
