Andy Murray has admitted that he faces an "incredible task" to win the US Open after having his fourth round tie against Donald Young postponed for two consecutive days.
Rain has halted almost all play at Flushing Meadows, allowing Murray to complete just three games against American Donald Young in the past two days.
This means that the Scot will have to play four best-of-five set matches in four days if he is to win the final Grand Slam of the year.
"It's an incredible task now," Murray told BBC Radio 5 Live.
"It's incredibly difficult anyway with the guys who are at the top of the game but there's not a whole lot we can do.
Novak Djokovic and Roger Federer have already progressed to the quarter-final stage but Rafael Nadal has also been stranded in the round of 16.
The Spaniard joined Murray and American Andy Roddick in voicing their concern at the referee's decision to send players out while it was still raining.
"[Referees] stand on the court and say it looks all right but, if you try moving at the speed we're moving at and changing direction, it's completely different. It just didn't make sense," Murray added.
Thursday's New York forecast indicates that more rain is due to hit Flushing Meadows.
If the rain does not materialise then Murray is due to continue his match with Young at 4pm BST.
