Andy Murray said he faces an "incredible" task to win his first Grand Slam title.
The Scot will try for a third time to reach the US Open quarter-finals later today in New York after rain played havoc with the schedule at Flushing Meadows over the last two days.
Only 15 minutes of play was possible yesterday, leaving the world No.4 facing the possibility of four matches in as many days if he is to break his major duck.
Murray managed to get out on court yesterday for his fourth-round match against Donald Young, with the American leading 2-1 on serve when the rain returned.
Defending champion Rafael Nadal, who dropped the first three games against Gilles Muller in slippery conditions, was very upset with the situation and demanded a meeting with tournament referee Brian Earley.
Nadal accused organisers of putting profit before player safety, saying: "Grand slams are (making) a lot of money and we are part of the show.
"They are working for that, not for us. I understand the fans want to see tennis, but the health of the players is most important and we do not feel protected."
Of his prospects for a first Grand Slam, Murray said: "It's an incredible task now."
SNOOKER: Seven-times world champion Stephen Hendry is set to lose his place in the elite world top 16 after he was beaten in round one of the Shanghai Masters.
Hendry, 42, has been in the top 16 and exempt from qualifying for big tournaments for the last 23 years. But he is now expected to have to qualify for December's UK Championship after losing 5-1 against Robert Milkins.
World champion John Higgins eased to a 5-2 victory over Mark Davis, while world No.1 Mark Williams whitewashed Andrew Higginson 5-0 and will now play Milkins in the next round.
