My French isn't the best, but apparently Roger plays a preparation tournament before the French Open which takes place from May 20th to 22nd. Other players in the field are Nadal, Murray, Nalbandian, Monfils, Blake or Safin.
You got it quite right there. Okay, a lousy attempt from my head:
Tennis stars will be in Paris before Roland-Garros
08/04/2009-[10:20] - Sports.fr
[The Paris Golf & Country Club of] Rueil-Malmaison will receive the top stars of worldwide tennis from 20 till 22 May, two days before the beginning of Roland-Garros, for the first Masters Guinot Mary Cohr[-tournament]. As such, Rafael Nadal, Roger Federer, Andy Murray, David Nalbandian, Gaël Monfils, James Blake or alternatively, Marat Safin, have been announced to compete for a preparation tournament on clay court at the city of Hauts-de-Seines. This will provide an opportunity for some of the big favourites for the French Open of 2009 to practice a last time before entering the stages on the courts of the Porte d'Auteuil.
Something like that.
So, IF THIS IS TRUE, Roger will indeed attend an (invitational) preparation tournament before RG. About which I have to admit having mixed feelings.
Skipping Estoril and Monte Carlo, but indeed appearing here? Hmmm hmmm.
