Roger Federer; born 8 August 1981 is a Swiss professional tennis player widely considered the greatest player of all time. He is currently ranked World number 1 by the ATP. He owns several men's world records of the Open Era: holding the number 1 position for 287 weeks overall; a 237-consecutive-week stretch at the top in 2004–2008; winning 17 Grand Slam singles titles; reaching the finals of each Grand Slam tournament at least five times (an all-time record); and reaching the Wimbledon final eight times. He is one of seven men, and one of four in the Open Era, to capture the career Grand Slam, and one of three (with Andre Agassi and Rafael Nadal) to do so separately on clay, grass, and hard courts. Federer also shares the Open Era record for most Grand Slam titles at the Australian Open with Agassi (4 titles), at Wimbledon with Pete Sampras (7 titles) and at the US Open with Jimmy Connors and Sampras (5 titles). Federer's ATP tournament records include winning six ATP World Tour Finals, playing in the finals at all nine ATP Masters 1000 tournaments, and, matching Agassi, winning seven. read more
