Did you guys watch his first round match? Unbelievable! His serve, his return, his defensive skills, his movement, just flawless!
Nadal is closer to Djokovic on Hard court as shown in the results in Indian Wells and Miami. But Nadal is not even close to Djokovic on Clay!
Why I am saying this? Because Djokovic is better in Clay than in Hard Court! Furthermore, the new ball being used is going to favor Djokovic, because it is harder and faster!
