Latisha Chan

2003–2005

While still a junior, Chan 2003 entered her very first pro-tour event in Taiwan. She reached the semifinals in singles and the quarterfinals in doubles. She started her professional career in 2004. By the end of the year, she already was the singles title holder of three $10,000 events, including Colombo, Jakarta 3, and Taipei. She also won three doubles titles at Jakarta 3, Haibara, and Mount Gambier. Her 2005 season got off to a strong start with a win at a $25,000 event in Taipei. She also won a $50,000 event in Fukuoka. Later that year, she qualified for the US Open, but failed to defeat Serena Williams in the first round. After the US Open, she played two qualifying events in Beijing and Seoul, but failed to enter the main draw. However, she teamed up with Chuang Chia-jung to win her first tour-level doubles title in Seoul.

2006

Chan played in the qualifying events of all four Grand Slams and qualified into the main draws in Wimbledon and the US Open, but failed to beat resurgent Australian Alicia Molik and Belgian Kirsten Flipkens, respectively. Her breakthrough and first tour-level win came at the Tokyo Open, where she reached the semifinal stage by defeating local favourite and two-time winner Ai Sugiyama. The victory marked her first top-30 win. She also participated in the doubles event and reached the finals, once again partnering Chuang Chia-jung.

On the Challenger Circuit, she won the singles titles in Melbourne, Fukuoka, Kurume, and Kaohsiung. Together with regular partner Chuang, she also won the doubles titles in Sydney, Gosford, Fukuoka, Kurume, and Kaohsiung. After her victory in Kaohsiung, she surged into the top 100 and was ranked No. 73 in singles.

2007

To establish herself at the WTA Tour level, Chan only participated in those events at the beginning of 2007. She entered the main draws of the Australian Open, at Pattaya, Bangalore, and Indian Wells, but failed to advance past the first round. In Miami, she reached the second round by defeating Nuria Llagostera Vives, before losing to top seed Maria Sharapova.

Chan finally found her footing after entering the clay court season. In Charleston, she qualified into the main draw, and stunned No. 39 ranked Séverine Brémond in two sets to set up a rematch against reigning Australian Open and Miami winner Serena Williams. Chan was 5–3 up before Serena retired with a groin injury. Her magical journey in Charleston ended in the third round, where she was defeated by Venus Williams in straight sets.

To improve her singles game, Chan entered three ITF pro events after Charleston and won all three of them. With the success in three events, her ranking rose to a career high No. 50 on June 11. In Bangkok, Chan reached her first WTA singles final, but lost to No. 49 ranked Flavia Pennetta in two sets.

Her singles achievements aside, Chan also had success in doubles in 2007. Awarded with a wildcard entry, Chan and Chuang reached the finals of the Australian Open, which was Chan's first Grand Slam doubles event. On their way to the final, they defeated 2006 US Open doubles finalists Dinara Safina and Katarina Srebotnik and 2006 Australian Open and Wimbledon champions Yan Zi and Zheng Jie. In February, the Chans participated in two more events. They reached the final at both Pattaya and Bangalore, and won the doubles title in the latter.

In their Indian Wells debut, the Chans again stormed into the final with back-to-back wins over 2006 Australian Open and Wimbledon champs Yan Zi and Zheng Jie in the quarterfinals, and 2006 US Open champions Vera Zvonareva and Nathalie Dechy in the semifinals. However, they lost the final to 2006 Roland Garros champions Lisa Raymond and Samantha Stosur in straight sets. Had they won the final match, they would have defeated every 2006 Grand Slam champion team in one single event. At that point, they had made it into the final in all six tour-level doubles events they had entered. Their finals streak was broken in Miami, when they lost to Raymond and Stosur in the semifinal.

2008

At the German Open in Berlin, Chan became the last player whom top-ranked Justine Henin ever defeated before she retired the following week. Chan represented her country at the Beijing Olympics, in both singles and doubles.^[5]

2009

Chan at the 2009 US Open

Chan started the season with an unexpected lead of 5–1 against Russian world No. 4, Elena Dementieva, in their first round match in Auckland. Chan ultimately lost the match to the eventual champion. After that, her results were uninspiring other than winning a round at the Australian Open, her first time to do so.

Chan was diagnosed with a fatigue fracture in her left foot, which stopped her season for three months after the Sony Ericsson Open in Miami to when the grass season kicked off. She suffered quite a number of upsets after her comeback, but rebounded just in time for the Asian tour in the autumn. She delighted home crowds by sweeping both the singles and doubles (with Chuang) titles in the Taipei 100K+H ITF tournament. For the fourth year in a row, Chan finished the season in the top 100.

On the doubles court, Chan shocked the world No. 1 team of Cara Black and Liezel Huber with Romanian Monica Niculescu, in the quarterfinals of the Premier level tournament in Stanford. They were defeated by Serena and Venus Williams in the title match after taking out another seeded pair of Maria Kirilenko and Sorana Cîrstea.

2010–2014

In the 2010 US Open, Chan beat two former WTA top-50s – Anne Keothavong and Tamira Paszek – to make her first round of 32 in a Grand Slam tournament, her previous best results had been the round of 64 at the 2008 US Open, 2009 Australian Open, and 2010 Wimbledon. In the third round, she lost 1–6, 0–6 to top seed and world No. 2 Caroline Wozniacki.

In the 2011 Australian Open, she reached the final of mixed doubles with Paul Hanley, their first Grand Slam final. Along the way, they defeated the defending champions, and fourth-seeded, Cara Black and Leander Paes, in two set-tiebreakers. However, this team lost the final to second seeds Daniel Nestor and Katarina Srebotnik in three sets.

Chan reached the semifinals of 2012 Mercury Insurance Open, losing to Marion Bartoli 6–1, 3–6, 3–6.^[6]

2014, she lost the title match of the Taipei WTA Challenger to Vitalia Diatchenko 6–1, 2–6, 4–6.^[7]

2015: Australian Open doubles final

Chan lost her third Grand Slam doubles final at the Australian Open.^[8] She and her sister won their fourth WTA doubles title together at the Western & Southern Open, and by doing so, now have the second-most doubles titles for a pair of sisters in WTA history after only Serena and Venus Williams. The Chans previous three WTA doubles titles came at Shenzhen in 2013, Eastbourne in 2014, and Pattaya City in 2015. Cincinnati represents their biggest title yet, their first at the Premier-5 level.^[9] They would go on to win another title at the Japan Women's Open in Tokyo.^[10]

2017: US Open doubles champion, world No. 1

In February 2017, Chan teamed up with former world No. 1 Martina Hingis for the women's doubles competition at the Dubai Duty Free Championship. Hingis had split from short-time American partner CoCo Vandeweghe due to limited success together. In March, Chan won at Indian Wells with Hingis, as they defeated Lucie Hradecka and Katerina Siniakova in the final.^[11] This was the first Premier Mandatory title for Chan, the first big title of her career.^[12] The team added titles in Madrid and Rome with final victories over Tímea Babos and Andrea Hlaváčková^[13] and Ekaterina Makarova and Elena Vesnina, respectively.^[14]

Chan and Hingis played their first Grand Slam tournament together at the 2017 French Open. They advanced to the semifinals, where they lost to the eventual champions, Bethanie Mattek-Sands and Lucie Šafářová.

In September, she and Hingis won their first Grand Slam women's doubles title together at the US Open when they defeated Hradecká and Siniaková in straight sets. This was their seventh title of the season.

They would win their next title at the Wuhan Open, their third Premier-5 crown of the year. The following tournament, the season's last Premier Mandatory event, they would win their ninth title of the season at the Beijing event. That means they won three out of the four Premier Mandatory events in 2017, only missing out on the Miami Open where they lost in the semifinals. It also meant that they won six of the nine Premier-5/Premier-Mandatory tournaments of the season.

2018: Struggles with form, French Open mixed doubles title

Chan has been struggling in 2018 since Hingis retired. Apart from winning her maiden mixed-doubles title in French Open with Ivan Dodig, she did not win any titles during her reign as world No. 1. Finally, Chan dropped out of that position after losing in the second round at Roland Garros. After a Premier title in San Jose (with Květa Peschke) and a Premier-5 final in Montreal (with Ekaterina Makarova), Chan returned to the No. 1 ranking in doubles only for one week before dropping out of top ten later in the rest of the season.
