Novak Djokovic is the only player to have held the World No. 1 spot for more than 100 weeks since turning 30

Novak Djokovic is the only player to have held the top position in the ATP rankings for more than 100 weeks since turning 30. The Serb recently began his 362nd week in the top spot, 138 of which have come since he turned 30. Rafael Nadal has held the top spot for 68 weeks in his 30s, while Roger Federer has managed only 25 weeks.

Novak Djokovic reclaimed the World No. 1 spot from Daniil Medvedev on Monday. The Russian lost to Gael Monfils in the third round of the 2022 Indian Wells Masters, losing 250 ATP points from his title defense in Marseille while gaining 45 points from making the third round. He currently has 8,410 points to his name and is 55 points behind Djokovic's tally of 8,465 points.

Djokovic has enjoyed tremendous success since entering his 30s in May 2017. Since then, the Serb has lifted eight Grand Slam titles as compared to Nadal's seven and Federer's four.

Other players who have been ranked World No. 1 in their 30s include Andre Agassi, Ivan Lendl, Jimmy Connors, and Andy Murray, who kept the top spot for a period of 33, 23, 17, and 41 weeks respectively.

Medvedev can once again claim the World No. 1 spot by reaching the semifinals of the 2022 Miami Open. The Russian is currently defending 180 points at the Masters 1000 tournament from his run to the quarterfinals last year.

Djokovic, meanwhile, is guaranteed to remain World No. 1 for a minimum of two weeks. The 20-time Grand Slam winner has withdrawn from the tournament and is likely to make his return at the Monte-Carlo Masters, a tournament he has won twice in his career.
