Persistent rain wiped out almost the entire day of US Open qualifying as organisers cut their losses early.
Only 14 of the 64 second round qualifying matches were able to start on Wednesday before the decision to cancel play for the day was made about 16:00 local time (21:00 BST).
The weather will not affect the climax of the new-look mixed doubles, with the semi-finals and final protected by the roof on Arthur Ashe Stadium.
British men's number one Jack Draper and his American partner Jessica Pegula are among the four teams aiming for the title from 19:00 local time (00:00 BST, Thursday).
