Nice to see the top four men in the world have made it through to the semifinals of the French Open, setting up what should be a spectacular series of showdowns ahead. Nadal, Federer, and Murray all won quarterfinals without the loss of a set. And Djokovic didn't have to set foot on court, advancing to the penultimate round with a walkover. So on Friday, five-time Paris champ Nadal will face Murray, who gave him a good test on the clay at Monte Carlo in April. And Djokovic--still unbeaten in 2011--will meet Federer, who appears to be in excellent clay court form.
