Carlos Alcaraz secured the year-end world number one status for the second time in his career following a sensational season which saw him triumph in the French Open and US Open.
With a tour-leading 70 wins and unmatched eight titles, the Spaniard pipped his adversary Jannik Sinner to top spot, who enjoyed a stellar season himself after adding a third and fourth Grand Slam title to his collection at the Australian Open and Wimbledon.

Andy Roddick's career-best season in 2003 saw him achieve year-end world number one status as he triumphed at the US Open and claimed six ATP titles.
14. Roger Federer
2004 essentially marked the dawn of the golden era as Roger Federer inherited year-end world number one from Roddick in that year and retained that status for four of the next five seasons, finishing top of the pile in 2005, 2006, 2007 and 2009.
15. Rafael Nadal
Rafael Nadal eclipsed his long-term rival Federer as a five-time year-end world number one in 2019 after previously finishing top of the pile in 2008, 2010, 2013 and 2017.
16. Novak Djokovic
The player who holds the record for most year-end finishes as world number one and will not be surpassed anytime soon.

Jannik Sinner was crowned year-end world number one in 2024 following a remarkable campaign which saw him win his first two Grand Slam titles at the Australian Open and US Open.
