Recent success of Serbian tennis players has led to an immense growth in the popularity of tennis in the country. Novak Djokovic has won eighteen Grand Slam singles titles and has held the No. 1 spot in the ATP rankings for a record total of 311 weeks. He became the eighth player in history to achieve the Career Grand Slam and the third man to hold all four major titles at once and the first ever to do so on three different surfaces. Ana Ivanovic (champion of 2008 French Open) and Jelena Janković were both ranked No. 1 in the WTA Rankings. There were two No. 1 ranked-tennis double players as well: Nenad Zimonjić (three-time men's double and four-time mixed double Grand Slam champion) and Slobodan Živojinović. The Serbia men's tennis national team won the 2010 Davis Cup and 2020 ATP Cup, while Serbia women's tennis national team reached the final at 2012 Fed Cup.
