Novak Djokovic

Novak Djokovic (born 22 May 1987) is a Serbian professional tennis player. He has been ranked as the world No. 1 in men's singles by the Association of Tennis Professionals (ATP) for a record 428 weeks, finished as the year-end No. 1 a record eight times, and has been ranked No. 1 at least once in a year for a record 13 different years. Djokovic has won 102 ATP Tour–level singles titles, including a record 24 majors (including a record ten Australian Open titles), a record 40 Masters titles, a record seven year-end championships, and an Olympic gold medal. Djokovic is the only man in tennis history to be the reigning champion of all four majors at once across three different surfaces. In singles, he is the only man to achieve a triple Career Grand Slam, and the first player to complete a Career Golden Masters, and the only player to accomplish it twice. Djokovic is the only player in singles to have won all of the Big Titles over the course of his career.

Djokovic began his professional career in 2003. In 2008, at age 20, he disrupted Roger Federer and Rafael Nadal's streak of 11 consecutive majors by winning his first major title at the Australian Open. By 2010, Djokovic had begun to separate himself from the rest of the field and, as a result, the trio of Federer, Nadal, and Djokovic was referred to as the "Big Three" among fans and commentators, and Big Four including Andy Murray, creating a Golden Era of men's tennis. In 2011, Djokovic ascended to No. 1 for the first time, winning three majors and a then-record five Masters titles while going 10–1 against Nadal and Federer. He remained the most successful player in men's tennis for the rest of the decade. Djokovic had his most successful season in 2015, reaching a record 15 consecutive finals and winning 10 Big Titles while earning 31 victories over top-10 players. His dominant run extended through to the 2016 French Open, where he completed the Career Grand Slam and a non-calendar year Grand Slam, becoming the first man since Rod Laver in 1969 to hold all four majors simultaneously and setting a rankings points record of 16,950.
