2001
As a native of Mallorca, Nadal is naturally trilingual in standard Catalan, Mallorquí (a dialect of Catalan), and Castilian Spanish. Since he began his pro career he has improved his English immensely. He speaks it with an accent but by most definitions he is fluent. He has also at times addressed the crowd at the French Open in French, although I am unaware of him ever using French in any other public forums, so it is difficult to say with any certainty how proficient he is in that language.
in 2001 when he was only 16 years old
He uses the new babolat aero pro drive strung with babolat RMP blasts.
You don't need a tour card to turn pro. He simply earned his after he turned pro.
He turned pro at age 16.
