#9 Toni Nadal

The partnership between Rafael and Toni Nadal began in the town of Manacor, Mallorca when the now 32-year-old Rafa was just four. Toni is the brother of Rafa's father, so their bond has always been quite close.
Toni was the one who insisted Rafa play with his left hand in order to get an advantage over right-handed opponents, who are in the majority.
Under Toni’s tutelage, Rafa became one of the most accomplished and mentally strong players on the men’s tour. His breakthrough came in the year 2005, when he won the first of a record 11 French Open championships.
With Toni as his coach, Nadal has won 16 of his 17 Grand Slam titles. Their long partnership came to an end by mutual consent at the end of the 2017 season. In fact, Toni even found a new successor to take over from his duties in Carlos Moya.
Nowadays, Toni is involved in promoting tennis at the grassroots level at the Rafael Nadal Tennis Academy in Mallorca.
