Roger Federer has called for US Open organisers to drop 'Super Saturday' as part of the final Grand Slam of the calendar year.
Federer, who is the head of the ATP Player's Council, wants the USTA to drop the historic part of the tournament, which sees both men's semi-finals and the women’s final played on the same day.
This year, the men’s final has been moved to Monday as a result of the heavy rain that has hit New York over the past few days.
But while players will have a day off in between their semi-finals, it will still affect several players, who are scheduled to be playing in the Davis Cup next week.
The Swiss Maestro also believes changes to the early stages of the tournament need to be made and is less than happy that the first rounds at Flushing Meadows are spread over three days.
"I think the three early first rounds is not working, and then the Super Saturday I just think is not feasible," he said.
"In all the Grand Slams you do not really have that competitive advantage over another player, which I don't think should be the case here.
"I'm sure that there has been many finals played here where one player had a huge advantage, and I don't think that should be happening before such a huge match here in the final.
"So I think that's where, you know, it was a good decision to make it a Monday final again. But without the roof, I just don't think Saturday/Sunday is feasible any longer at this point."
He added: "I have to fly down to Australia on Tuesday or whatever to get there Thursday to play [Davis Cup] Friday. So is that good? No, it's not good for anybody who has to play the following week to play Monday.
"You never have it that we have to play back-to-back best of five set matches, and only here before the final at the US Open.
"It just somehow doesn't make a whole lot of sense to me."
