First, the tennis event is finished on the middle Sunday of the games...giving those who reach final matches a week in between that and Toronto. All the top players will be at both 1000 events.
I know that the tennis is finished early but I have seen many athletes at the closing ceremonies that had finished much earlier. So I didn't know whether the athletes themselves just decide whether they want to hang around and spectate after they are finished. If you are saying that tennis requires the players to be at the 1000 events, that answers my question. Thanks!
