Karolina Pliskova is set to be announced as the new WTA World No.1 when the updated rankings are released on Monday, July 17. The 25-year-old becomes the first player representing the Czech Republic to accomplish this since the computer rankings were introduced in 1975, and would be the 23rd woman overall to hold the No.1 ranking.

Even though Martina Navratilova was born in Czech Republic, when became WTA World No.1 she was representing USA. Pliskova’s ascent to WTA World No.1 brings an end to the reign of Germany’s Angelique Kerber, who spent 34 non-consecutive weeks in the position, which is the 12th longest of all time.

This is another feather in the cap in a blossoming career and comes off the back of her third WTA title of the season at the Aegon International Eastbourne. In the last 52 weeks – the period of time on which the rankings are based – Pliskova has won four WTA titles, reached the the final of the US Open, the semifinals of the French Open and two Premier Mandatories, and defeated a Top 10 player nine times. Since 2015, she has smashed more aces on tour than any other player.

“To be crowned the WTA No.1 player in the world is the ultimate accolade in our sport, and I would like to send my warmest congratulations to Karolina on this incredible achievement. Karolina is an exemplary athlete on and off the court and she truly deserves this fantastic moment in her career.” said WTA CEO Steve Simon.
