Premise: Rafael Nadal . 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 . By winning the 2014 French Open , Nadal became the third player to win a single Grand Slam tournament nine times ( Martina Navratilova 9 , Margaret Court 11 ) and the first male to win at least one Grand Slam tournament for ten consecutive years , breaking the record of eight consecutive years previously shared by Björn Borg , Pete Sampras , and Roger Federer .
Hypothesis: Rafael Nadal has won at least two Grand Slam titles on three different holidays.
