Novak Djokovic has extended his dominance at the top of the ATP rankings by posting his 406th week as World No. 1.
As the ATP season begins on a clean slate in 2024, Djokovic remains the only player with five-digit ranking points. The Serb has built an enormous lead over second-placed Carlos Alcaraz, which stretched to 2,390 points.
Alcaraz is not in action until the Australian Open, while Djokovic is playing in the United Cup, where he was instrumental in powering Serbia to an opening group-stage win over China in Perth.
Djokovic has an opportunity to win a maximum of 500 ranking points at the mixed-gender team competition but is set to drop 250 ranking points from winning the Adelaide International last year.
The 24-time Grand Slam champion is not assured of the World No. 1 beyond the Australian Open. That is because Alcaraz doesn't defend any points in January and has room to gain over the Serb in his fresh pursuit of the top spot.
The rest of the world's Top 10 remains as it was at the end of last season. Daniil Medvedev, Jannik Sinner, and Andrey Rublev comprise the top five positions. Rublev is in action in Hong Kong this week and could narrow the gap between himself and Italy's Sinner.
If his fitness issues persist, Greece's Stefanos Tsitsipas could risk dropping outside the world's Top 10. Tsitsipas is sixth in the world rankings but is defending 225 points at the United Cup and runner-up points at the Australian Open.
Alex de Minaur and Tommy Paul are aiming to break the world's Top 10 for the first time. The Aussie could do so if he manages to take his country into the latter stages of the United Cup, while Tommy Paul could realistically do so if he produces another deep run in Melbourne.
Casper Ruud is also playing at the United Cup and has been unbeaten so far in singles. The Norwegian is targeting a return to the world's Top 10. A host of ATP stars are in action in the opening week of the season in one of three tournaments.
