....use a one-handed backhand and a midsize 90 sq. in. racquet. Just like Federer proved today in Madrid. All these other top pros like Djokovic, Murray, Verdasco, Roddick, Ferrer, etc. with their two-handed backhands and big midplus 98-100 sq. in. racquets are futile against Nadal on clay. So if you want to beat Nadal on clay, you need to switch to a one-handed backhand and a 90 sq. in. racquet.
