What makes Robin Soderling different at RG compared to other flat hitters like Querrey, Cilic, Isner, Berdych, Blake, Roddick (well he used to be), ect? His movement is nothing special, and actually he hasn't had very good results on other clay surfaces. But once again at the French Open, Soderling is playing fantastic tennis. I'd say he is playing the best out of the top 10 atm. What is it about this surface that makes his game click, when it doesn't have the same effect for other big hitters?
