There have been a lot of "Baby Federers" over the past 10 years; Dimitrov is but the latest. This is because Federer's game is classically beautiful, a combination of old-school values and modern-power necessity. But there have been no "Baby Nadals." Perhaps by forcing the preadolescent Rafa, a natural right-hander, to play tennis left-handed, Nadal's uncle Toni created a Frankenstein's monster. No one else can produce the kind of avalanche topspin and psychedelic sidespin that Nadal offers up with his forehand. Federer has employed an assembly line of southpaws over the years as practice partners, but none have been able to prepare him for Rafa. Add Nadal's revolutionary forehand to his warrior spirit and his obsessive drive to improve, and you have a player like none before.
