It was all right in the days when tennis was a less physical sport. Johnny Mac played 5 sets against Connors late into the night in 1984 and then came back and destroyed Lendl in the final the next day. Now though it seems rather daft. On the other hand, I suppose it's good that each slam presents its own unique challenges.
Huh? Roger won it 5 times in a row in "these days."
People want to dismiss the USO and say RG is the toughest slam to win, but I noticed no one is wishing that RG change it's format to make it easier on the players. The USO has long been the toughest slam to win, and the final weekend is a big part of that.
Anyway, you're the same whiners who will be crying foul when a semi at one of the other majors goes into a second day because there's no 5th set tiebreaker.
