"He is currently ranked as
world No. 1 by the
Association of Tennis Professionals (ATP). Djokovic has been No. 1 for 308 weeks, and has finished as
year-end No. 1 on six occasions, an
Open Era record shared with
Pete Sampras. Djokovic has won 17
Grand Slam men's singles titles, including a record eight
Australian Open titles. He is the only player to win all of the elite tournaments on the modern
ATP Tour – that is, all four Grand Slam tournaments, all nine
ATP Masters 1000 tournaments, and the
ATP Finals. In particular, he is also the only player to complete the
career Golden Masters, which he has done twice. Overall, he has won 81 ATP singles titles, including a record eight
Australian Open titles and a record 36 Masters events.
Djokovic began his professional career around the time
Roger Federer and
Rafael Nadal established themselves as the two dominant players in men's tennis. At age 20, he interrupted their streak of 11 consecutive majors to win his first Grand Slam singles title at the
2008 Australian Open. By 2010, Djokovic also separated himself from the rest of men's tennis to join Federer and Nadal in the
Big Three, the group of players who have dominated men's tennis through the end of the next decade.
[a] In 2011, Djokovic was ranked No. 1 for the first time, winning three out of four majors and his first five Masters events of the year. He remained the best player in men's tennis for the rest of the decade, leading the tour in major and Masters titles, and winning four out of his five titles at the ATP Finals consecutively from 2012 through 2015. After four consecutive year-end finishes at No. 3 through 2010, Djokovic finished No. 1 six times and No. 2 three times in the next ten years.
Djokovic had another career year in 2015, reaching fifteen consecutive finals, including all four major finals and eight Masters finals, winning three majors and six Masters events as well as the ATP Finals. The following year, he won the
2016 French Open to complete the
career Grand Slam. He also became the first male player since
Rod Laver in 1969 to hold all four major titles at once and the only male player in history to do so on three different surfaces. After long trailing both
Federer and
Nadal in their head-to-head records, Djokovic has since taken the lead against them. Representing Serbia, Djokovic has led the
Serbia Davis Cup team to their first title in
2010, and also led Serbia to a title at the inaugural
ATP Cup in 2020. He won a bronze medal in singles at the
2008 Beijing Olympics."
