World No. 3 Rafael Nadal has reached another milestone by registering more than 15,000,000 fans on his official Facebook page.
Rafa joined Facebook 5 years ago, on March 30, 2009. On March 10, 2012, he hit the 10 million milestone.
Our champ still has a little way to go before he catches up with Maria Sharapova, who has more than 15.3 million Facebook fans on her official page.
