WTA rankings are the official world rankings for female tennis players, and are used to determine qualification for the sport's most prestigious tournaments. Ashleigh Barty is still the world No 1, and is closing in on Serena Williams' record for time spent at the top, while Emma Raducanu moved down to 13th.

The WTA rankings are based on a 52-week, cumulative system, where rankings are based on points from tournaments.

For example, winning a Grand Slam competition is worth 2,000 points, while simply qualifying is worth 70 points.

Players with the most points are seeded higher for competitions - while also claiming the all-important bragging rights.

Naturally, the biggest moves tend to happen after a Grand Slam finishes - as they're worth the most points - but there's still plenty of chances to move up the leaderboards after ATP 250 or ATP 500
