Claim: Rafael Nadal has won at least two Grand Slam titles on three different surfaces.
Evidence: Nadal has won 14 Grand Slam singles titles , the 2008 Olympic gold medal in singles , an all-time record of 30 ATP World Tour Masters 1000 titles , tied with Novak Djokovic , and a record 18 ATP World Tour 500 tournaments.
Nadal and Mats Wilander are the only two male players who have won at least two Grand Slam titles on three different surfaces -- hard court , grass , and clay.
In 2016 , he became the eighth player in history to achieve the Career Grand Slam ; by winning the 2016 French Open , Djokovic became the third man to hold all four major titles at once , the first since Rod Laver in 1969 , and the first ever to do so on three different surfaces.
