Novak Djokovic<\/a> ushered in a record-extending 400th week atop the PIF ATP Rankings in style in November 2023.<\/p>\n \nMore than 12 years after he first rose to World No. 1, the Serbian downed Jannik Sinner<\/a> to earn a record seventh title at the coveted Nitto ATP Finals<\/a>. His reward for that Turin triumph was an unprecedented 400th week at World No. 1, beginning the following day, 20 November 2023.<\/p>\n \n“It’s a pretty good achievement, 400 weeks at No. 1. It’s never been done in history,\u201d said Djokovic, who also clinched ATP Year-End No. 1 presented by PIF for a record eighth time that week. \u201cSomeone will eventually break it, but hopefully it stays there for a long time.\u201d<\/p>\n \nDjokovic\u2019s journey to the milestone achievement began on 4 July 2011, when he became the 25th player to join the ATP No. 1 Club. At age 24, Djokovic downed rival Rafael Nadal<\/a> in the Wimbledon<\/a> final, claiming his first of seven triumphs at the All England Club. Djokovic had already secured his debut atop the PIF ATP Rankings by defeating Jo-Wilfried Tsonga<\/a> in the semi-finals.<\/p>\n \nSpanning from December 2010 to Roland Garros<\/a> in 2011, Djokovic enjoyed an impressive 43-match winning streak, only halted by Roger Federer<\/a> in the semi-finals of the clay-court major. But Djokovic\u2019s dominance was just taking flight. He tallied a standout 70-6 match record in 2011.<\/p>\n \nDjokovic has at times dominated the sport, collecting 101-tour level trophies and spending a record 428 weeks at No. 1. His 419th week as World No. 1 was historic: On 1 April 2024 \u2014 then 36 years and 321 days old \u2014 Djokovic surpassed Federer as the oldest No. 1 in PIF ATP Rankings history. <\/p>\n \nThe Belgrade native has lifted a record 24 major titles and 40 ATP Masters 1000 crowns. In 2018 in Cincinnati, Djokovic became the first player in Masters 1000 history to win all nine elite tournaments and complete the career Golden Masters. Two years later, at the same event, Djokovic completed his second career Golden Masters.<\/p>\n
