Rafael Nadal (ESP)  vs Andy Murray (GBR) . Murray did not even play this tournament last year because of an injury but is playing in his 2nd career Roland Garros semifinal and 15th career major semifinal overall. Despite the fact that he has had his best results on hard courts, he is experienced on clay. However, like he does against all his contemporaries Nadal leads Murray 14-5 including 5-0 on clay.
Some of us didn't even think he would win his previous match against Gael Monfils in front of a Parisian crowd. Nadal has lost three times on clay this year (to Novak Djokovic in Rome, David Ferrer in Monte Carlo and Nico Almagro in Barcelona) so he is more vulnerable (and less confident) in Paris than he has ever been. However, it must help the King of Clay's confidence that he was able to dispatch one of these rivals surprisingly easily when he beat Ferrer 4-6 6-4 6-0 6-1 in the quarterfinals. I'm fairly confident that Murray will put up a better fight than that, but the eventual result will almost certainly be the same. Mad Professah's pick: Nadal in 4.
surprised me by following up his dismissal of Roger Federer in the 4th round with a straight-sets shellacking of Tomas Berdych in the quarterfinals. The Latvian is finally living up to his prodigious talent and is most definitely a dangerous player but the inevitable high-stakes clash between the World #1 and World #2 is unlikely to be derailed by this 1st time major semifinalist. Instead, for the third consecutive year, the winner of the clash between Nadal and Djokovic is almost certainly going to determine the winner of the French Open (and probably the year end World #1 ranking). Mad Professah's pick: Djokovic in 4.
