In 2011, Djokovic was ranked No. 1 for the first time, winning three out of four majors and a then-season record of five Masters events. 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 for six years and No. 2 for three years in the next decade.
Djokovic had another career year in 2015, reaching fifteen consecutive finals, including all four major finals and eight Masters finals, winning three majors and a season-record of six Masters events as well as the ATP Finals. The following year, he won the 2016 French Open to complete the career Grand Slam and the non-calendar year 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 one in history to do so on three different surfaces. By winning the 2021 French Open, he became the first player in the Open Era to achieve the career Grand Slam twice. Representing Serbia, Djokovic has led the Serbian team to their first Davis Cup title in 2010 and to the inaugural ATP Cup title in 2020.
