Karolina Pliskova: The Ace Machine Who Refused to Walk Away
In the summer of 2024, Karolina Pliskova tore the ligaments and tendons in her left ankle at the US Open. Two operations later, she did not know if she would ever play again. In 2026, at 34, she was back in a WTA 1000 quarter-final. If you like comeback stories, hers is one of the quiet great ones of this season.
Pliskova is a former world No. 1, a two-time Grand Slam finalist and one of the best servers the women's game has ever seen. Here is her story, from the courts of northern Bohemia to the top of the rankings and back again.
Early Life: One of Two
Karolina Pliskova was born on 21 March 1992 in Louny, in what was then Czechoslovakia. She has an identical twin, Kristyna, who also became a professional player. The difference fans learned to spot: Karolina is right-handed, Kristyna is left-handed.
Karolina showed her promise early, winning the Australian Open junior title in 2010. Her rise on the senior tour was steady rather than spectacular, but by 2016 she was one of the most dangerous players in the world.
The Serve
At 1.86 m, Pliskova built her game around a serve that few players could read. The numbers are remarkable:
- In 2016 she hit 530 aces, the most by any player in a single season in WTA history.
- She led the WTA Tour in aces in 2015, 2016, 2017 and 2019.
Behind the serve was a flat, aggressive baseline game. She took the ball early and hit it hard and low over the net, especially off the backhand. Her calm, almost expressionless on-court manner sometimes made her look detached. In fact it was part of her strength: she rarely let a bad game turn into a bad set.
Grand Slam Finals
Pliskova never won a major, but she came close twice:
- 2016 US Open: On her way to the final she beat both Williams sisters, Venus and Serena, and then lost a tight three-setter to Angelique Kerber.
- 2021 Wimbledon: She fought back from a set down to force a decider against Ashleigh Barty on Centre Court and lost 6-3, 6-7, 6-3.
She also reached the semi-finals of the Australian Open (2019) and the French Open (2017).
World No. 1
On 17 July 2017, Pliskova became world No. 1. She was the first Czech woman to reach the top of the rankings and one of a small group of women to become No. 1 without having won a Grand Slam. She qualified for the WTA Finals five years in a row from 2016 to 2021 (the event was not held in 2020), reaching the semi-finals three times.
Her 17 WTA singles titles include big ones: the Cincinnati title in 2016, the Italian Open in 2019 and Brisbane several times. She has earned around $26.8 million in official prize money, which places her among the top 15 earners in WTA history.
She was also a key member of the Czech Fed Cup (now Billie Jean King Cup) teams that dominated the competition in the mid-2010s. In the 2016 final against France in Strasbourg, she teamed up with Katerina Siniakova to win the deciding doubles rubber and bring the trophy home.
Matches to Remember
- 2016 Cincinnati final: she beat Angelique Kerber in straight sets, stopping the German from taking the No. 1 ranking that week. It was the biggest title of her career at that point, and the start of her best run.
- 2016 US Open semi-final: she beat Serena Williams, then the world No. 1, in straight sets to reach her first Grand Slam final, having beaten Venus Williams in the fourth round after saving a match point.
- 2019 Australian Open quarter-final: trailing Serena 1-5 in the final set and facing four match points, Pliskova won six games in a row to reach the semi-finals. It is one of the great escapes of recent Grand Slam history.
- 2019 Italian Open final: she beat Johanna Konta to win the title in Rome, one of the biggest clay-court events in the women's game.
- 2021 Wimbledon semi-final: after a string of difficult seasons, she outserved Aryna Sabalenka to reach her second major final.
The Injury and the Year Away
After a difficult couple of seasons, Pliskova had a lovely moment in February 2024, winning the Transylvania Open in Cluj, her first title in four years. Months later came the ankle injury at the US Open.
The recovery took two surgeries and a long rehabilitation. She sat out the rest of 2024 and all of 2025. She has said that during this time she genuinely did not know whether the recovery would work well enough for her to return. She spent the year at home with her family, and she has described that time away as giving her a completely different perspective on life and on tennis.
The 2026 Comeback
Pliskova returned at the start of 2026, and the results came faster than almost anyone expected:
- Australian Open: third round, in her first Grand Slam for well over a year.
- Madrid Open: a run to the quarter-finals, her first WTA 1000 quarter-final in two years.
- Italian Open: fourth round in Rome.
She has talked about playing now without long-term goals or pressure, simply enjoying being back on court. She has been working with coach Zeljko Krajan. By the summer she had climbed back into the top 100.
Why She Is Worth Watching
Pliskova's game was built for a certain kind of tennis: big serve, first strike, short points. The tour has become faster and more physical since her peak, and she is now one of the oldest players in most draws. And yet, when her serve is landing, she can still beat almost anyone on a quick court.
To understand how quickly a player can climb back from zero, it helps to know how the WTA ranking points system works. After a long absence you start again almost from scratch, and the only way back is to win matches. Pliskova has been doing exactly that.
