| Bio | She is a Dutch former professional tennis player. Her career-high WTA singles ranking was world No. 4, which she reached on May 13, 2019, becoming the highest ranked Dutch female player ever. Her career-high doubles ranking of world No. 16, she achieved in April 2018. She won ten singles and ten doubles titles on the WTA Tour including 2018 Cincinnati Open and 2019 Madrid Open. Bertens was widely regarded as a clay court specialist, but also was successful on hardcourt. Bertens was born in Wateringen near The Hague, but grew up in the town of Berkel en Rodenrijs. She has two sisters, one older and one younger. Bertens started playing tennis at age six at ATV Berkenrode, a tennis club where her aunt and uncle played. She has been coached by Martin van der Brugghen at the club since she was seven years old. Van der Brugghen recognized her ability and continued to coach her primarily to help her reach her potential. He said: "In the youth we have supported her very much. I taught her for little money because I find it interesting to see how far you can get with someone." Bertens received little support from the Dutch tennis federation. She did not play on the ITF Junior Circuit except for one appearance at the Junior Fed Cup in 2007. Bertens started the year playing the qualifiers for the Australian Open. In the first round against top seed Vesna Dolonc, she won the first ten games before Dolonc retired. In the second, Bertens lost to Olga Savchuk in a close three-set match. The following week, in a $25k event in Andrézieux-Bouthéon, Bertens retired with a thigh injury in the first round against Corinna Dentoni. She played in the Fed Cup for the Dutch team, competing in Group 1 of Europe/Africa. She partnered with Demi Schuurs in the doubles match against the Portuguese team of Bárbara Luz and Margarida Moura and won in two sets. Bertens won her singles rubber against Estonia's Eva Paalma and with Michaëlla Krajicek double-bageled Anett Kontaveit and Tatjana Vorobjova. Late February she played the qualifications for WTA tournament of Acapulco. She defeated Mexican wild card Ana Paula de la Peña in the first round but lost in the second qualification round to Sesil Karatantcheva. At a $25k event in Irapuato, Mexico, Bertens won her second ITF singles title, beating Yaroslava Shvedova in the final, propelling her to a new career high in singles ranking. The following week, she made it to the quarterfinals of the $25k tournament in Poza Rica, but her winning streak was snapped by Jana Čepelová. At the $25k tournament in Bath the week afterwards, Bertens won the title, defeating Annika Beck in the final in three sets, her fourth three-set match in a row. Bertens failed to qualify for the WTA Tour tournament in Copenhagen, falling to Johanna Konta. In the qualifying for the WTA Tour event in Fes, she beat Moroccan wildcard Intissar Rassif without dropping a game. She reached her first WTA tournament final in this tournament, defeating Urszula Radwańska, sixth seed Chanelle Scheepers, Garbiñe Muguruza, and fifth seed Simona Halep along the way. Prior to this event, she had never won a WTA singles match in the main draw. In the final, she defeated Laura Pous Tió, winning the last eight games. She became the first Dutch female player since Michaëlla Krajicek in 2006 to win a WTA singles tournament. At the French Open, Bertens was seeded No. 1 in qualifying and defeated Annika Beck in the first qualifying round, saving a matchpoint in the third set. She defeated Olga Puchkova in the second round and outclassed Mădălina Gojnea in the final qualifying round. This meant Bertens' first main-draw appearance at a Grand Slam tournament. In the first round, she lost in three sets to Christina McHale. Bertens debuted at Wimbledon in her first-round match against the No. 19 seed Lucie Šafářová and won in two sets, her first win at a Grand Slam event. In the second round, she lost to Yaroslava Shvedova in straight sets. Bertens then made a brief appearance at an ITF tournament in Biella, but lost to homeplayer Nastassja Burnett in the first round. This was followed by first-round losses in Palermo and Båstad to Alexandra Cadanțu and Polona Hercog, respectively. Bertens returned to form during the American hardcourt circuit. In Montreal, she qualified by defeating Vladimíra Uhlířová, Zhang Shuai, saving two matchpoints, and Alexa Glatch. In the main draw, Bertens caused an upset, defeating former world No. 3 (then ranked 22) Nadia Petrova, coming back from a large deficit. In the second round, Caroline Wozniacki proved too strong, and Bertens lost in straight sets. Like in Montreal, Bertens qualified for the main draw in Cincinnati, defeating Aravane Rezaï and Yulia Putintseva. However, in the main event she succumbed to fellow qualifier Sesil Karatantcheva. In Dallas, she retired with a shoulder injury against Polona Hercog. At the US Open, Bertens exacted revenge on Christina McHale, knocking out the American in the first round but suffering a three-set loss to Olga Puchkova in the second round. Bertens stated afterwards she had been nervous during the match. At the WTA tournament in Seoul, Bertens defeated Vania King and Sílvia Soler Espinosa from Spain to reach the quarterfinals. She faced Estonian Kaia Kanepi next and lost in straight sets. After a second-round appearance in Linz she ended her season with a first-round loss in Luxembourg due to fatigue.

She reached the semifinals with wins over Tamira Paszek, fourth seed Dominika Cibulková, and sixth seed Lucie Šafářová. In the semifinals, Bertens faced top-seeded Sara Errani. Errani led 5–0 in the first set when Bertens retired due to a back injury. At the 2014 French Open, she reached the fourth round as a qualifier in which she was defeated in three sets by Andrea Petkovic. In 2015, she changed coaches from Christiaan de Jong to Raemon Sluiter. Bertens started the 2016 year in Auckland, where she entered the main draw as a qualifier. She lost in the first round to Barbora Strýcová. At the Hobart International, she reached the quarterfinal, losing there to Dominika Cibulková. She lost in the first round of the Australian Open to Laura Siegemund. Bertens then earned two important wins in the Fed Cup tie against Russia, beating Ekaterina Makarova and Svetlana Kuznetsova. They ended up beating the 2015 finalists.[20] After that, Bertens had early defeats in Acapulco (losing to Naomi Osaka in the first round) and in Monterrey (losing in the last round of the qualifying to Pauline Parmentier). After entering Indian Wells' main draw as a qualifier, she lost in the first round to CoCo Vandeweghe. Prior to the Miami Open, she played at the San Antonio Open where she reached the round of 16. Then, in Miami, she once again reached the main draw through qualifying and earned wins over Zheng Saisai and No. 25 seed Anastasia Pavlyuchenkova before retiring in the third set in her third-round match against Angelique Kerber. Playing for the Netherlands at the Fed Cup semifinals against France, Bertens kept her winning streak by beating Caroline Garcia and Kristina Mladenovic, both in straight sets; nonetheless, it was not enough as France won the tie in the doubles decider. After that, she started her clay-court season with a semifinals run in Rabat, only losing to Marina Erakovic. At Nuremberg, Bertens won her second WTA singles title by defeating Mariana Duque Mariño in the final in straight sets. In the second round, she had defeated top-seeded Roberta Vinci which was her first win against a top-10 player. And it was her first title since 2012. She also won the doubles title alongside Johanna Larsson. At the French Open, Bertens avenged her Miami loss by upsetting No. 3 seed Angelique Kerber in three sets. She then beat Camila Giorgi, No. 29 seed Daria Kasatkina, No. 15 seed Madison Keys, and No. 8 seed Timea Bacsinszky en route to her first Grand Slam semifinal. In her semifinal match against the No. 1 seed Serena Williams, Kiki played with a left calf injury which made it difficult for her to move forward to Williams' drop shots. Bertens never took advantage of a medical time-out or took trainer treatment. Despite having two set points and being up by a break in both sets, she lost in straight sets. However, she entered the top 30 for the first time in her career. Prior to Wimbledon, Bertens was scheduled to play at the Rosmalen Open; however, due to the same injury that harmed her left calf, she was forced to pull out of the tournament. After a few weeks of recovery, Bertens kicked off her campaign at the third Grand Slam event of the year and defeated Jeļena Ostapenko and Mona Barthel to reach the third round of the grass tournament for the first time. She then lost to Simona Halep. Her next tournament was the inaugural Ladies Championship Gstaad, where she reached the final. She lost one set to Tamira Paszek en route. In the final, Bertens lost in three sets to Viktorija Golubic. Despite the defeat, she climbed to No. 21 in the rankings. Despite winning her second title of her career this year and making it to the semifinals of the French Open, Bertens lost in the first round of six straight tournaments, notably including the Rio Olympics and US Open. As a result of her inconsistency, she decided not to compete at the Wuhan Open and China Open. She made her return at the Linz Open. However, she lost in the first round to Sorana Cîrstea but won the doubles with Johanna Larsson. Her next event was the Luxembourg Open. She had her best result since Wimbledon by making it to the semifinals, losing to Monica Niculescu. However, she did not go home empty handed. Bertens and Larsson won their second doubles title in a row. Bertens ended her season at the WTA Elite Trophy where she lost both of her matches with close scorelines, against Elina Svitolina and Elena Vesnina. Bertens started her 2017 year off with a first-round loss to Lauren Davis at Auckland. However, Bertens and Larsson won the doubles title. Kiki was seeded first at Hobart. She had routine wins over Annika Beck and Galina Voskoboeva in the first two rounds, but lost to qualifier and eventual champion Elise Mertens. She continued to struggle during her next four tournaments, and lost in the first round of all of them including the Australian Open. She then traveled to the United States for the Indian Wells and Miami Open, and lost to Timea Bacsinszky at Indian Wells in a hard-fought three-setter, and in the second round in Miami to qualifier Risa Ozaki. Bertens had a strong start into clay-court season. She reached the third round of both the Charleston Open and the Copa Colsanitas, then lost in the first round of the Porsche Grand Prix. However, she made it to the quarterfinals of the Madrid Open, defeating former top-ten players Makarova and Bacsinszky along the way, before losing to Anastasija Sevastova. Bertens had an even more impressive journey during the Italian Open where she made it to the semifinals, eventually losing to Simona Halep. She defended her title in Nuremberg by defeating Barbora Krejčíková in the final – her third career singles title. After a strong showing during the clay-court season, she entered the French Open and beat Ajla Tomljanović in the first round, but was upset by CiCi Bellis in the second. Bertens started the grass-court season with two straight first-round losses at the Rosmalen Open and Mallorca Open. The Wimbledon Championships proved to be unsuccessful as well as she lost in the first round to Sorana Cîrstea. After a disappointing French Open and Wimbledon, Bertens rebounded at Gstaad where she claimed the title by beating Anett Kontaveit in the final. She also claimed the doubles title alongside Johanna Larsson. Bertens had a poor US Open Series as she lost in the second round of the Cincinnati Open to Johanna Konta. She followed this up with a first-round loss at the Connecticut Open in Cincinnati to qualifier Elise Mertens. She was then defeated in the first round of the US Open by Maria Sakkari, in straight sets. At Korea Open, Bertens was seeded second, but lost in the first round against compatriot Richèl Hogenkamp. She lost in the second round of the Wuhan Open to qualifier Varvara Lepchenko, and in the first round of both the China Open and Austrian Open.

In the quarterfinals, she lost to Julia Görges but achieved a career best at Wimbledon so far by reaching the last eight. After Wimbledon, Bertens decided not to defend her title on the clay of Gstaad. She started the hardcourt season in Montreal at the Canadian Open where she made an impressive run, beating for the first time two top-ten players on hardcourt. She defeated ninth seed Karolína Plíšková and eighth seed Petra Kvitová before losing to 15th seed Ashleigh Barty in the quarterfinals, her best performance in Montreal.

Bertens started off her clay-court season at the Charleston Open as defending champion and reached the third round before losing her match against Maria Sakkari, in straight sets. She reached the semifinals at the Porsche Grand Prix in Stuttgart, losing in three sets to Petra Kvitová. However, she bounced back at the Madrid Open, where she cruised through her first three matches against Kateřina Siniaková, Jeļena Ostapenko, and Anastasija Sevastova.

At Roland-Garros, she reached the fourth round, defeating Sara Errani in three tight sets in the second round which saw her leaving the court in a wheelchair. After the match, Errani accused Bertens of faking her injury. Bertens subsequently fell to another Italian player Martina Trevisan in the fourth round and announced the following month that she would undergo surgery to treat an Achilles tendon injury, sidelining her for the remainder of the season. Bertens ended the year ranked No. 9 in the world for the second year in a row. Bertens was sidelined for the start of the 2021 season, following surgery on her Achilles tendon at the end of 2020.

Her final tournament was the doubles draw at the same event, where she partnered Demi Schuurs. They won their first-round match against French pair Kristina Mladenovic and Caroline Garcia, in three sets, then lost to Elena Vesnina and Veronika Kudermetova, also in three sets. Bertens retired from the professional tour ranked No. 24 in singles and 112 in doubles. Bertens was a baseline player, who was noted for her ability to combine her exceptional defensive skills with an aggressive mindset. As she played aggressively, taking the ball early on the rise, she tended to hit large numbers of both winners and unforced errors. Bertens' greatest asset was her forehand, which was powerful and hit with heavy topspin, allowing her to hit winners from any position on the court. Her heavy topspin forehand had the added benefit of pushing her opponents behind the baseline, forcing them to play defensively from the first stroke. Her two-handed backhand was also strong, and she was able to dictate play using this stroke; despite this, her backhand was less reliable than her forehand, and her backhand was responsible for the majority of the unforced errors she committed on the court. She was adept at applying slice to her backhand, which allowed her to break up the pace of baseline rallies, and draw unforced errors from more aggressive players. Her first serve was powerful, typically being delivered at 105 mph (169 km/h), and peaking at 110 mph (177 km/h), allowing her to serve aces, and dictate play from the first stroke of the rally. Bertens' second serve was less reliable, leading to a relatively high double fault count; throughout her career, however, Bertens began to develop a more effective kick serve, which minimised double faults. Despite being an effective net player due to her doubles experience, Bertens rarely approached the net when playing singles, except to retrieve short balls, or to attack the net when the opportunity arose. Bertens possessed an exemplary drop shot, and was one of the strongest exponents of this shot on the WTA Tour; this shot was especially effective on clay courts, where she would deploy the shot during long baseline exchanges, to surprise opponents and move them around the court. Due to her exceptional fitness, movement, fitness, footwork, and court coverage, Bertens was an adept counterpuncher, and these skills allowed her to execute her playing style with tremendous effect. Although Bertens experienced success on all surfaces, her favourite surface was clay, where the high bounce and slow speed suited her playing style; her clay court game was aided by her ability to slide and move effectively on the surface. Despite all these strengths, Bertens' game was heavily affected by nerves throughout her career, and her lack of Grand Slam success despite being one of the most consistent players on the WTA Tour was credited to the nerves she felt when playing in front of large crowds. |
