Roger Federer is a Swiss professional tennis player widely considered the greatest player of all time. By the time he was eleven years of age, Federer was among the Top 3 junior tennis players in Switzerland. His professional debut came in 1998, and he knocked out the reigning champion Pete Sampras in the fourth round at the 2001 Wimbledon. Federer became the first Swiss man to win a Grand Slam title when he won the Wimbledon 2003 singles trophy. He is ranked World number 2 by the ATP as of March 2013. Federer owns several men's world records of the Open Era: holding the number 1 position for 302 weeks overall with a 237-consecutive-week stretch at the top from 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. In 2006, Federer won the Australian Open, his fourth successive Wimbledon singles title and his third successive U.S. Open. 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 of those at least once. In 2012, Federer defeated Novak Djokovic in the Wimbledon semifinal and Andy Murray in the final to become the Wimbledon 2012 champion for his seventh Wimbledon win. This victory helped Federer gain back the No. 1 spot. Federer has appeared in 24 men's Grand Slam finals and participated in 18 of 19 finals from the 2005 Wimbledon Championships through to the 2010 Australian Open. Besides the titles, the medals and the trophies, Roger Federer has won the ATPWorldTour.com Fans' Favorite Award a record nine times straight (2003–2011), the Stefan Edberg Sportsmanship Award (voted for by the players) a record seven times (2004–2009, 2011), the Arthur Ashe Humanitarian of the Year Award in 2006 and the Laureus World Sportsman of the Year for a record four consecutive years (2005-2008).
