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 held.
