Roger Federer
Swiss tennis player (born 1981)
Roger Federer ( FED-ər-ər; Swiss Standard German: [ˈrɔdʒər ˈfeːdərər]; born 8 August 1981) is a Swiss former professional tennis player. He was ranked as the world No. 1 in men's singles by the Association of Tennis Professionals (ATP) for 310 weeks (second-most of all time), including a record 237 consecutive weeks, and finished as the year-end No. 1 five times. Federer won 103 singles titles on the ATP Tour, the second most since the start of the Open Era in 1968, including 20 major men's singles titles (among which a record eight men's singles Wimbledon titles, and an Open Era joint-record five men's singles US Open titles), 28 Masters and six year-end championships.
For nearly two decades, Federer was a leading figure in men's tennis alongside Rafael Nadal and Novak Djokovic, collectively known as the Big Three, and including Andy Murray, the Big Four, creating the Golden Era of men's tennis. A Wimbledon junior champion in 1998 and former ball boy, Federer won his first major singles title at Wimbledon in 2003 at age 21. For the next several years Federer was the dominant player in men's tennis, playing in 20 out of 24 major singles finals between 2004 and 2009. He won three of the four majors and the Tour Finals in 2004, 2006, and 2007, as well as five consecutive titles at both Wimbledon and the US Open. Federer completed the career Grand Slam at the 2009 French Open after three consecutive runner-up finishes to Nadal, his main rival until 2010.
