8 times. He subsequently won his 9th title at three more tournaments; 2016 Monte Carlo, 2016 Barcelona, and the 2019 Italian Open. In 2018, he became the sole record-holder for most titles at the ATP 500 (Barcelona), Masters 1000 (Monte Carlo), and Grand Slam (French Open) levels. He also holds the longest single-surface win streak in the Open Era, having won 81 consecutive matches on clay between April 2005 and May 2007. Nadal has never been taken to five sets in 14 French Open finals, and has never lost consecutive matches on clay since the start of his professional career. Many tennis critics and top players regard him as the greatest clay-court player of all time. Nadal's 14 French Open titles are a record for one player (male or female) at a single major, surpassing the old record of 11 Australian Open titles won by Margaret Court. Nadal is the only player to defeat Roger Federer in the finals of three different Grand Slam tournaments as well as on three different surfaces (2009 Australian Open on hard court, 2006 French Open on clay court, and 2008 Wimbledon on grass court). He has won 6 hard-court majors (2 Australian Open & 4 US Open titles), tied with Andre Agassi for fourth-most behind Pete Sampras (7), Federer (11) and Novak Djokovic (13) in the Open Era. Nadal is the first player to win four Grand Slam titles without dropping a set (2008, 2010, 2017 and 2020 French Opens) surpassing the old record of three titles held by Björn Borg. He is also the first player, male or female, to win 100 matches at the French Open and holds the all-time record for the most match wins at a single major, with 112 at the French Open. He is the only player, male or female, to record three streaks of four or more consecutive titles at a single major in their career (2005–2008, 2010–2014 and 2017–2020 French Open), surpassing the old record of 3 consecutive Wimbledon titles won by Sampras twice (1993–1995, 1997–2000). Nadal is the only player to bagel both Federer (2008 French Open) and Djokovic (2020 French Open) and defeat both in straight sets in Grand Slam finals. He has won the most ATP titles (30 titles) without dropping a set, with 26 of these titles won on clay courts and 4 on hard courts. Nadal is the sixth player to
