It was his second French Open title and second major title overall. It was the first of three consecutive years Nadal and Federer would contest the French Open final. This marked Federer's first defeat in a major final; he was attempting to complete the career Grand Slam and to become the first man since Rod Laver in 1969 to hold all four major titles at once, having won the preceding Wimbledon, US Open and Australian Open titles. The latter feat would ultimately be achieved a decade later by Novak Djokovic, at the same tournament, who here reached the quarterfinals at a major for the first time.
Two-time defending champion Roger Federer defeated Andy Roddick in the final, 6–2, 4–6, 7–5, 6–1 to win the men's singles tennis title at the 2006 US Open. It was his third US Open title and his ninth major title overall. Federer became the sixth man to reach all four major finals in one calendar year, the second to do so in the Open Era, and the first to do so since Laver in 1969. Also, he reached a record-equalling 10th consecutive major semifinal, after Laver and Ivan Lendl.
Defending champion Roger Federer defeated Fernando González in the final, 7–6(7–2), 6–4, 6–4 to win the men's singles tennis title at the 2007 Australian Open. It was his third Australian Open title and his tenth major title overall. Federer became the first man to win a major without dropping a set since Björn Borg at the 1980 French Open, and the first to do so in a major played on hardcourts. Also, Federer made a record-equaling seventh consecutive major final appearance, after Jack Crawford during the 1930s, and became the first man to reach eleven consecutive major semifinals. González became the first Chilean to reach a major final since Marcelo Ríos in 1998.
Novak Djokovic defeated Guillermo Cañas in the final, 6–3, 6–2, 6–4 to win the men's singles tennis title at the 2007 Miami Open. It was his first Masters singles title, and the first of an eventual record 38 Masters titles.
