RF has an Eastern backhand grip, which is great for low balls and is why he has won so many Wimbledon's and US Opens. However, on clay courts the balls bounce much higher, making his backhand even more difficult and he commits many more errors. I think he should look to another person who has won many French Opens with a OHBH and that is Justin Henin. She had an extreme eastern backhand and she did fine. To deal with the high balls and spin that a clay court makes even more pronounced, he should rotate his grip and he would do better against Nadal and co. Another thought just popped into my head. At the AO, those forehands from rafa into his backhand gave RF the most trouble. What if he used the extreme eastern grip for RG and against Rafa on hard courts? Would this improve his game against Nadal? I realize he is the 2nd best clay courter, but he will have a tougher time this year with the (seemingly) stronger field. This could give him his French Open title which he longs for.
