The mantle of world number one in tennis is something every player aspires for but few ever achieve. 

When it comes to men's singles, only a handful of names have held top spot over the past two decades. 

But a new generation of talent is coming through with young players pushing their way up the rankings. 

Who is the current men's world No. 1?

Carlos Alcaraz is the current men's world number one.

The Spaniard won the 2022 US Open to secure top spot and became the youngest male to ever be crowned world No. 1 in the process.  

He replaced Daniil Medvedev at the summit with the Russian failing to defend the title he won a year ago after being knocked out in the round of 16.

In the latest rankings update, Rafael Nadal has jumped up to second spot - the highest he's been in over a year.

How do tennis rankings work?

Tennis world rankings are calculated by the ATP, who award points based on a player's performance at particular tournaments. 

The further a player progresses in a sanctioned event, the more points they will be awarded. 

Grand slams provide the most points with 2000 awarded to the winner and 1200 to the runner-up. 

Points picked up from each tournament last for one year with rankings updated each week. 


When are tennis rankings updated?

Both the ATP and WTA update their rankings every Monday when tournaments aren't running. 

So in general you can expect weekly updates aside from when Grand Slams are being competed.
