With Roland Garros planning a new stadium with a moveable roof for 2014, the New York venue remains the only one of the four majors left out.

Wimbledon's moveable roof over Centre court debuted this summer while the Australian Open has boasted two covered showcase arenas for years.

Late news from the Nadal camp was not encouraging, with American broadcasters reporting that the world number three re-aggravated an abdominal muscle pull he's been carrying for a month, during his first set on Thursday night against Gonzalez.

On the men's side, Roger Federer and Novak Djokovic went safely through into the semis two days ago, while Argentine Juan Del Potro beat Croatian Marin Cilic on Thursday to book his place in the final four against either Nadal or Gonzalez.

The weather problems are made even worse by the scheduling habits of the Open, which insists on putting two men's semi-finals and the women's final on Saturday to rake in millions in television dollars.
