This table is current through the 2020 Qatar Open.

During the summer hard-court season between Wimbledon and the US Open, Hsieh struggled in both singles and doubles. Her best showings came in singles at the Citi Open, where she lost to young American Caty McNally in the quarterfinals, and the third round of the Premier 5 Cincinnati Masters, losing to Osaka in three sets in the pairs third meeting of 2019. At the US Open, she lost to Wimbledon quarterfinalist Karolína Muchová in the second round in singles, while in doubles she and Strýcová were beaten in the third round by Kichenok and Ostapenko. Nonetheless, Hsieh and Strýcová became the first doubles team to qualify for the 2019 WTA Finals during the US Open.

While Hsieh continued to play a hefty chunk of ITF tournaments during the 2017 season, she also managed to post more respectable results on the WTA tour. Though she only managed to improve her year-end singles ranking by one placement, up to No. 96, she had arguably her biggest singles breakout in over four years at the French Open. Ranked outside the top 100 going into the tournament, Hsieh pulled off the biggest win of her career by defeating reigning Miami Open champion and world No. 8, Johanna Konta, in the first round, her first ever singles victory over a top-10 player. She then defeated Taylor Townsend to advance to the third round for the first time at the French Open, and the first time at any Grand Slam since Wimbledon in 2012. She was defeated by hometown favorite Caroline Garcia in an intense three-set match, where the final set went to 9–7 in favor of Garcia. Hsieh also reached the final of the Hua Hin Championships, a WTA 125k series event, in November, her biggest singles final in five years, but lost to former top ten player Belinda Bencic.

The 2016 season was a relatively quiet one for Hsieh. While she finished the year ranked just inside the top 100 in singles, poor results in the middle of the year kept her from jumping beyond her peak year ranking of No. 65. Her best results on the WTA Tour came with a semifinal appearance in Taiwan, a quarterfinal showing in Prague, and progressing to the second round at the Australian and French Opens. Unlike the last few seasons, Hsieh played more singles matches on the ITF Circuit, reaching a $100k final in Marseille in June and winning a different $100k tournament in Dubai in December, her 27th ITF singles title.

After a difficult 2016, Hsieh also managed to recapture some of her strong doubles form. Partnering Oksana Kalashnikova, they won the Budapest Grand Prix in February, her 18th career WTA doubles title, and her first since winning the French Open in 2014. Throughout the season, she played alongside a multitude of different female players, but found the most success working with Monica Niculescu. With the Romanian, they won inaugural version of the Swiss Ladies Open in April, reached the final of the Cincinnati Masters, and reached the third round of the US Open. Additionally, she won a $100k doubles title in May at Cagnes-sur-Mer with Chang Kai-chen, her 23rd ITF doubles title, and the WTA 125k doubles title in Hawaii in November with her younger sister, Hsieh Shu-ying. She finished the year ranked No. 32 in doubles, a very substantial improvement from the previous year.

Hsieh opened the season by reaching the semifinals at the Auckland Open, her first WTA singles semifinal since the WTA Taiwan Open in February 2016. She lost to eventual champion Julia Görges. Hsieh's next tournament came at the Australian Open. After coming from behind to defeat Zhu Lin in her opening match, she caused the biggest upset of the tournament thus far by defeating the third seed and reigning Wimbledon champion, Garbiñe Muguruza, in straight sets. She continued this impressive display by taking out 26th seed and former world No. 2, Agnieszka Radwanska, in straight sets to reach the fourth round of a Grand Slam since she did so at the Australian Open ten years earlier. Facing Angelique Kerber, she won the first set, but was ultimately defeated by the German player. Hsieh also had a successful doubles tournament, reaching the semifinals with Peng Shuai, her best performance in a slam since they won the French Open. She returned to inside the top 75 of the singles rankings and the top 30 of the doubles rankings after the Australian Open.

After the Australian Open, Hsieh had a relatively quiet rest of the early hard-court season singles-wise. After losing the qualifying rounds in Doha and Dubai, and a second-round loss at the Oracle Challenge, Hsieh qualified into the main draw at Indian Wells and progressed to the second round. Her best result came at the Miami Open where she advanced to the third round for the first time, losing to Karolína Plíšková. She had a very successful doubles performance, though, reaching the final in Dubai with Peng, and winning the Indian Wells title with Barbora Strýcová, her 20th career WTA doubles title. This victory put her back in the top 20 of the doubles rankings.

After early round losses at the Thailand Open in singles and the Qatar Open in singles and doubles, Hsieh regained her form at the year's first Premier-5 event, the Dubai Championships. Unseeded in the singles draw, she breezed past tenth seed Anastasija Sevastova in the first round and Aliaksandra Sasnovich in the second round. She then caused a huge upset in the third round by defeating former World No. 1 and reigning Wimbledon champion Angelique Kerber in three sets. In the quarterfinals, she posted another comeback three set win over the fourth seed Karolína Plíšková, winning the last six games in a row after being down 5-1 and on a nine-game losing streak in the final set to advance to her first Premier 5 semifinal. Facing Kvitová for the second time in two months, she was unable to get revenge on the Czech and lost in three sets despite winning the first. Hsieh also played doubles in Dubai, reuniting with Barbora Strýcová. Seeded third, the pair went on to win the title defeating Lucie Hradecká and Ekaterina Makarova in the final in two sets. She next played at Indian Wells, losing her only singles match to Johanna Konta and reaching the quarterfinals in doubles. Seeded 27th at the Miami Open, Hsieh defeated Alison Riske in her first match to set up a rematch with Osaka in the third round. This time, it was Hsieh who came back from both a set down and a service break down in the second and third sets to uphend the Australian Open champion, her second victory over a World No. 1 in the last twelve months. She continued her great run by defeating former world No. 1 and 13th seed, Caroline Wozniacki, in the fourth round to advance to her first Premier Mandatory quarterfinal, where her tournament came to an end against the 21st seeded Estonian Anett Kontaveit.

With doubles competition in the way, Hsieh missed all the singles events during the clay season except French Open, where she lost in the first round of qualifying. In doubles, she came through one of the most difficult doubles draws with Peng by defeating unseeded Svetlana Kuznetsova and Sam Stosur in the first round in straight sets, breezed through former No. 1, 15th seed Liezel Huber and Lisa Raymond in the third round, grinded three sets with fifth seed Sania Mirza and Cara Black in the quarterfinals and Garbiñe Muguruza and Carla Suárez Navarro, whom they lost to in Madrid, in the semifinals and defeated second seed Errani and Vinci in the final in straight sets for their second Grand Slam title. They were unable to defend their title at Wimbledon though, falling in the third round to eventual runners-up Tímea Babos and Kristina Mladenovic despite winning the first set. They also lost in the third round at the US Open to the team of Kimiko Date-Krumm and Barbora Záhlavová-Strýcová. Their best result throughout the remainder of the year came at the WTA Finals in Singapore. They easily won their first two matches, but were thrased in the final round by Cara Black and Sania Mirza, winning just one game. While Hsieh finished the year No. 144 in singles after a difficult year in which she won only seven main draw WTA matches, she finished ranked No. 5 in the world for doubles, her second straight top five finish.

At the Australian Open, Hsieh lost in the qualifying first round for singles, and main-draw second round for doubles, but she reached the semifinals in mixed doubles with Pablo Cuevas. Her best result in singles for the remainder of the year on the WTA Tour was reaching the semifinals in Kuala Lumpur. She only managed to compile three WTA match wins afterward, defeating former world No. 15, Kaia Kanepi, to reach the second round at Wimbledon and a quarterfinal appearance at the Japan Open. On the ITF Circuit, however, she was more successful. In April, she won two $25k tournaments held back-to-back in Shenzhen and Nanning, the latter being her 25th ITF singles title. She later won a $100k tournament in Nanjing in November.

The following year, Hsieh once again failed to qualify for either the Australian or US Opens, but qualified for the main draw at both the French Open and Wimbledon, where she lost in the first round both times. In doubles, she fell in the first round at three of the Grand Slams, but made it to the second round at the French Open. Hsieh made a breakthrough though in doubles, starting with reaching two finals in Auckland and Bangalore in the first two months of the year with different partners. She then earned the biggest wins of her career with compatriot Chuang Chia-jung as the pair won the China Open, a Tier II tournament. This marked Hsieh's first title of any kind on the WTA Tour. They won a second title together the following week at the Hansol Korea Open, where she had reached her first WTA final three years earlier. She once again performed well on the ITF level, winning a pair of titles in both singles and doubles. While she finished the year ranked No. 143 in singles, she snabbed her first year-end top-50 ranking in doubles, also her first top-100 ranking, by finishing 46th in the world.

At Doha, Hsieh won her first doubles title with Peng Shuai in 2014 and reached a career-high of world No. 2 in doubles. Later in May, with the semifinal run in doubles at Madrid, Hsieh will share the No. 1 ranking with Peng for at least a week, establishing the first individual in Taiwan to receive the No. 1 ranking in tennis, whether in singles or doubles, male or female. However, she failed to defend her title with Peng in Internazional BNL d'Italia by losing to Medina Garrigues and Shvedova in the second round in straight sets.

Hsieh had a quiet clay court season in singles, her best result coming in Morocco where she reached the quarterfinals. However, she continued her doubles success with Strýcová as the pair won their second Premier Mandatory doubles title at the Madrid Open, defeating Gabriela Dabrowski and Xu Yifan in the final. She concluded her clay court season at the French Open. Seeded 25th in singles, Hsieh was defeated by 2014 French Open semifinalist Andrea Petkovic in the second round. In doubles, she was seeded third with Strýcová, but they were upset in the third round by Lyudmyla Kichenok and Jelena Ostapenko.

Hsieh posted mixed results during the Asian hard-court season for singles and doubles. Her best singles result came at the Japan Open, where she was the defending champion and the number one seed for the first time in a WTA singles tournament in her career. However, she was upset by Nao Hibino in the quarterfinals. In doubles, she made the final of the Toray Pan Pacific Open with her sister Hsieh Yu-chieh, where they were beaten by fellow-Taiwanese siblings Latisha Chan and Angel Chan. However, she and Strýcová came into the WTA Finals on a three-match losing streak after posting consecutive first round losses in Wuhan and Beijing. Seeded second, the pair dropped their opening match to Dabrowski and Xu, but beat Barbora Krejčíková and Kateřina Siniaková, and Stosur and Zhang in their next two matches to finish first in the Purple Group. They defeated the No. 8 seeds Anna-Lena Grönefeld and Demi Schuurs in the semifinals, but were beaten by the defending champions, Babos and Mladenovic, in the final. Hsieh finished the year ranked No. 32 in singles and No. 4 in doubles, her first top 10 finish since 2014.

Regarded as Taiwan's most successful tennis player of all time, and one of the greatest tennis players Asia has ever produced, Hsieh has won three singles and 27 doubles titles on the WTA Tour, one WTA 125K series doubles title, 27 singles and 23 doubles titles on the ITF Circuit, seven medals at the Asian Games (two gold, three silver, and two bronze), a gold and bronze medal at the 2005 Summer Universiade, and has amassed over $8.4 million in prize money. On 25 February 2013, she reached her career-high singles ranking of world No. 23, and on 12 May 2014, she reached No. 1 in the world in the doubles rankings. She is the first (and to date, only) Taiwanese tennis player in history to achieve a top-25 ranking in singles, and the first to achieve a world No. 1 ranking in doubles. She regained the world No. 1 doubles ranking for the first time in nearly six years in February 2020 and has spent a total of twelve weeks in this position.

Known for playing with two hands on both sides, her flat, quick groundstrokes, her crafty gameplay, aggressive volleys, and unorthodox variety of shots, Hsieh is regarded as one of the most successful and versatile doubles players in history. She has won three Grand Slam titles in doubles, winning the 2013 Wimbledon Championships and the 2014 French Open with Peng Shuai, whom she also won the 2013 WTA Tour Championships with, as well as the 2019 Wimbledon Championships with Barbora Strýcová. Hsieh and Strýcová also were the runners-up at both the 2019 WTA Finals and the 2020 Australian Open, and she reached the quarterfinals in singles at the 2012 London Olympics with compatriot Chuang Chia-jung. Though she has yet to win a Grand Slam on hard courts, most of her titles have come on hard courts, including six of her Premier Mandatory/Premier 5 titles. She is also a three-time Grand Slam semifinalist in mixed doubles, reaching this stage at the 2009 US Open with Kevin Ullyett, the 2011 Wimbledon Championships with Paul Hanley, and the 2015 Australian Open with Pablo Cuevas.

After Hsieh having won the 2013 Wimbledon doubles title, her father said that a Chinese company had offered her a sponsorship deal worth 10 million yuan ($1.63 million) per year, on the condition that she switch her citizenship to the People's Republic of China. His remarks caused controversy in Taiwan as Hsieh stated that she would consider taking the offer. In response, the government of Taiwan mobilized domestic companies to offer her competing deals.

Peng and Hsieh opened their summer hard-court partnership with a victory at the Premier 5 Cincinnati Masters, defeating Anna-Lena Grönefeld and Peschke in the final. After an opening-round loss in New Haven, and a defeat at the hands of Sania Mirza and Zheng Jie at the US Open, the pair won their fourth title of the year at the Guangzhou International Open and WTA Tour Championships. After posting back-to-back semifinal finishes at the Pan Pacific Open and China Open, Hsieh qualified with Peng for the WTA Tour Championships for the first time in her career. Seeded second, they defeated Nadia Petrova and Katarina Srebotnik in the semifinals and Ekaterina Makarova and Elena Vesnina in the final to win the year-ending championship, and their fifth title of 2013. By virtue of this win, Hsieh and Peng became the first Asian players to ever win a season-ending tennis championship. She finished her doubles season ranked No. 3 in the world, while her singles ranking dropped 60 places from 2012 down to No. 85.

Hsieh played two grass-court warmup tournaments before Wimbledon. In Mallorca, she suffered two first round losses, to Caroline Garcia in singles, and Anastasia Rodionova and Nadiia Kichenok in doubles, but fared better in Eastbourne with a third-round appearance in singles and the semifinals in doubles. Her singles performance was enough to push her ranking inside the top 50 for the first time since September 2013. Unseeded and placed in a very difficult top quarter, Hsieh opened up her Wimbledon campaign with a first round win over Anastasia Pavlyuchenkova, followed by a straight sets victory over Lara Arruabarrena Vecino to advance to the third round at Wimbledon for the first time in six years. She then recorded the biggest victory of her career by upsetting world No. 1, Simona Halep, who had just won the French Open four weeks prior, in a tight three setter where she had to come from a set down and save match points, thus advancing to her second Grand Slam fourth round of the year, and her first ever outside of the Australian Open. She lost her next match to Dominika Cibulkova in straight sets. She didn't fare quite as well in doubles, losing in the third round. Nonetheless, her singles performance saw her return inside the top 40.

Hsieh continued her amazing comeback at her next tournament, the Japan Women's Open. Seeded second, she defeated Polona Hercog, Mandy Minella, Ajla Tomljanović, and Wang Qiang en route to the final. Facing 17-year old American Amanda Anisimova, one of the youngest players on tour, Hsieh defeated the young upstart in straight sets to win her third career WTA singles title, and her first in six years. As a result of her victory, her singles ranking returned inside the top 30 since February 2013. At the Korea Open immediately after, Hsieh reached the semifinals in the singles tournament before falling to Tomljanović, and made the doubles final with her sister Hsieh Yu-chieh, but they fell to the all-Korean team of Choi Ji-hee and Han Na-lae. The remainder of Hsieh's results for the season were uneventful, exceptful for another semifinal singles appearance at the Tianjin Open, where she was beaten again by Garcia. Thanks to her renaissance career year in singles, consistent results, and the withdrawals of a few higher-ranked players, Hsieh was invited to serve as the second alternate to the WTA Elite Trophy, which she accepted, although she did not end up competing. She finished the year ranked No. 28 in singles, her best finish since 2012, and No. 17 in doubles.

Hsieh started the year strong with another semifinal run at the ASB Classic, where she fell to qualifier Bianca Andreescu, then a second round loss in Sydney to Petra Kvitová. At the Australian Open, she was seeded 28th in the singles draw, her first seed in any Grand Slam tournament since 2013. After tallying easy wins over Stefanie Vögele and Laura Siegemund, she would succumb to world No. 4 and reigning US Open champion, Naomi Osaka, in the third round. Despite winning the first set and obtaining a 4–1 lead in the second, Osaka, who went on to win the tournament and claim the world No. 1 ranking, won eleven of the last twelve games to come back and claim the match. She teamed up with Abigail Spears in the women's doubles tournament, where the pair was seeded eighth, but they were upset by eventual champions, Sam Stosur and Zhang Shuai, in the second round.

Many top players have praised her unusual playing style. Maria Sharapova, after her third-round win over Hsieh at Wimbledon 2012, said, "I faced her many times in the juniors. She used to be a nightmare for me because she used to slice and dropshot on clay. I was like, 'Where did they learn how to play tennis like that?' She uses both hands, switches racquets. That's her game: it's to hit a lot of dropshots and slices and get people kind of crazy. We used to have real battles in the juniors. I knew her game really well and I don't think she had time to do all of that today on grass. If I'm hitting a hard‑paced shot, I don't think she really has time to create, which is something that she really likes to do."

Hsieh experienced a career resurgence to her singles game during the 2012 season. After falling in her second qualifying match in Melbourne, Hsieh reached her first ever WTA singles semifinal at the Pattaya Open in Thailand, after having to qualify for the main draw. This result brought her singles ranking back inside the top 150. At the next tournament, the hard-court Malaysian Open at the beginning of March, she breezed through the qualifying tournament as the top seed, en route to advancing to her first WTA singles final. Despite dropping the first set, she won the title after her opponent, Petra Martić, was forced to retire while trailing 4–1 in the final set due to severe cramping and fatigue. This marked Hsieh's first career singles title on the WTA Tour, and made her the first Taiwanese tennis player to win an ATP or WTA singles title. She also returned to the top 100 for the first time since January 2009 following her victory. Also playing sporadically in ITF tournaments, she won the $50k tournament in Wenshan, her 21st ITF singles title. Hsieh's early season success allowed her to directly enter the main draw at the French Open, her first Grand Slam main draw appearance since the 2009 Australian Open. However, she was beaten in the first round by 18th seed Flavia Pennetta.

Playing primarily on the ITF Circuit for singles in 2011, Hsieh won three titles, a $25k in Mildura, a $75k in Beijing, and a $25k in Seoul, while also finishing as the runner-up at the $25k in Fergana. She also reached the quarterfinals at the Australian Open with Chuang, falling to Azarenka and Kirilenko, and won one WTA doubles title in Guangzhou with Zheng Saisai, her eighth career title and first in two years.

Hsieh got off to a slow start to the summer hard-court season. She played just one tournament between the Olympics and the US Open, the Texas Tennis Open. In singles, she was beaten by eventual champion Roberta Vinci in the first round, while falling in the quarterfinals of the doubles tournament with partner Gabriela Dabrowski to Iveta Benešová and Barbora Záhlavová-Strýcová. At the US Open, she suffered a three set loss in singles to Magdaléna Rybáriková in the first round, but was successful in the women's doubles tournament with partner Anabel Medina Garrigues, where they reached the semifinals. Hsieh piled together a hugely successful Asian hard-court season following the Open, winning 17 of her last 21 matches. She won the Ningbo Challenger, a $100k tournament, defeating Zhang Shuai in the final. The next week, she reached the final at the Guangzhou International Open dropping just one set en route. Facing the 17-year old Brit Laura Robson, the silver medalist in mixed doubles with Andy Murray at the Olympics who had defeated both four-time Grand Slam Champion Kim Clijsters and 2011 French Open champion, Li Na, en route to the fourth round at the US Open less than a month earlier, Hsieh played the most intense tennis match of her life. Despite being 0–2 down in each of the first two sets, having five match points saved in the second set, the match being suspended after the second set due to the excruciatingly hot temperatures, and then being 0–3 down in the final set, she fought back to win the title in three sets by a score of 6–3, 5–7, 6–4. This marked Hsieh's second WTA singles title of the year, and with it she jumped into the top 50 of the singles rankings for the first time, at No. 39. Though her 10-match winning streak was snapped in her very next match at the Pan Pacific Open, she won another $100k ITF singles title two weeks later at the Suzhou Open, her 23rd career ITF singles title. This brought her into the top 25 for the first time, becoming the first Taiwanese tennis player to achieve a ranking that high. Hsieh concluded her season at the Tournament of Champions, where she was invited to compete for the first time. She lost her first two matches to Caroline Wozniacki and Vinci, but ended her year on a high note with a three set victory over Hantuchová. Hsieh finished with her best year-end ranking to date, world No. 25 in singles, a ranking which she equaled in doubles.

At the Cincinnati Open, Hsieh lost in the first round in singles, but made it to the finals in doubles with Kazakh partner Yaroslava Shvedova. However, the pair were topped by the Russian duo of Maria Kirilenko and Nadia Petrova in a third set super-tiebreak. She then went on to record her first main draw win at the US Open over Evgeniya Rodina before losing to Petrova in the second round. Hsieh then managed to end the year strong by winning the Bali International with Peng Shuai and defending her title in Korea with compatriot Chuang. She finished the year ranked inside the top 100 in singles for the first time, at No. 79, and 53rd in doubles.

Hsieh lost in the first round of the Guangzhou International Open to Han Xinyun. This was her only main-draw WTA match of 2010.

During the clay season, she fell in first round of the Madrid Open, Italian Open, and French Open and the second round of the Internationaux de Strasbourg in singles, but won the Italian Open with Peng, her tenth career doubles title. While Hsieh would struggle throughout the rest of the season on the singles court, winning five of her next eighteen matches, and her best results being second round showings at the next two Grand Slam events, her Italian Open title sparked the beginning of what would go on to be a remarkable run of doubles titles and domination over the next twelve months. After a disappointing second round loss at the French Open, and quarterfinal losses at both grass court warmup tournaments, Hsieh and Penn came into Wimbledon as the dark horse candidates for the title. Seeded eighth, the pair wizzed through to the final with the loss of just one set, and without having to face a single seeded team. Facing the twelfth seeded Australian duo of Ashleigh Barty and Casey Dellacqua, they won the title in two sets. This was Hsieh's first Grand Slam title, making her the first Taiwanese tennis player to ever win one in any discipline. It also meant she would return to the top 10 rankings for the first time since January 2010.

Entering the summer hard court season, Hsieh reunited with her friend and compatriot Chuang Chia-jung, whom she would spend the majority of the rest of the season playing with. Their first tournament back was at the Cincinnati Masters, where they reached the semifinals. En route, she was able to get revenge on Babos and Mladenovic, who had beaten her at Wimbledon, with a win over the pair in the quarterfinals. Hsieh decided to play with Anastasia Rodionova, though, instead of Chuang at the US Open. The pair, seeded tenth, were upset in the second round by Anna-Lena Grönefeld and CoCo Vandeweghe. She also played mixed doubles with Henri Kontinen, where they reached the quarterfinals. Hsieh played two more tournaments with Chuang, the inaugural Dongfeng Motor Open in Wuhan and in Beijing, but they lost both opening round matches. She finished the year ranked 107th in singles and 26th in doubles.

Hsieh also struggled remarkably with doubles during the year, failing to make a single quarterfinal at WTA level. Her best result on tour came in a third round appearance at the Australian Open, also marking the first time since 2010 she failed to advance to the quarterfinals in at least one of the Grand Slams. As a result, she dropped down to playing primarily on the ITF level for most of the season, where she managed to win the doubles title in Marseille, a $10k title in Porto, and finishing as the runner-up in the doubles draw in Dubai. While her ITF level results managed to keep her inside the top 100, nonetheless, her year-end ranking of No. 96 marked her worst finish in ten years.

Hsieh opened the 2009 season by winning the doubles title with Peng at her first tournament of the year, the Premier-level Sydney International, defeating Nathalie Dechy and hometown favorite Casey Dellacqua in the final. At the Australian Open, she was upset by compatriot Chan Yung-jan in the first round of women's singles. As a result, she dropped out of top 100. In women's doubles, however, she and Peng fared much better. As the 16th seeds, the pair recorded back to back three set wins to advance to the third round, where they pulled off a major upset with a straight sets win over the second seeds Anabel Medina Garrigues and Virginia Ruano Pascual, losing just one game, thereby advancing Hsieh to her first major quarterfinals. However, the pair was defeated in the last eight by the eventual champions, 10th-seeded Serena Williams and Venus Williams.

While she is primarily known for her doubles prowess, Hsieh has also found decent success on the singles tour. Most of her singles success has come on hard courts, where she has won all three of her WTA titles, as well as reached the fourth round at the Australian Open in 2008 and 2018, a Premier 5 semifinal at the Dubai Tennis Championships in 2019, and a Premier Mandatory quarterfinal at the Miami Open in 2019. However, she has also been successful on other surfaces, including reaching the fourth round at Wimbledon in 2018, the third round at the same tournament in both 2012 and 2019, and the third round of the French Open in 2017. Hsieh has recorded singles victories over several top 10 and top 5 players, including Simona Halep, Naomi Osaka, Garbiñe Muguruza, Angelique Kerber, Karolína Plíšková, Aryna Sabalenka, Johanna Konta, Daniela Hantuchová, Anastasija Sevastova, Kimiko Date-Krumm, Flavia Pennetta, Jelena Ostapenko, Agnieszka Radwańska, Caroline Wozniacki, and Lucie Šafářová.

Su-wei started 2008 by winning three matches to qualify for the Australian Open, where she won her first main-draw Grand Slam match, defeating Klára Zakopalová in three sets. In the second round, she beat 19th seed Sybille Bammer and defeated Aravane Rezaï in the third round to become first Taiwanese tennis player to reach the fourth round of a Grand Slam. She then lost in the fourth round to the world No. 1, Justine Henin, in straight sets. The result would lift her into the top 100 for the first time. She reached the doubles final at the Thailand Open in February with Vania King, losing to compatriots Chuang and Chan Yung-jan.

Hsieh began the grass-court season by reaching the quarterfinals at the $75k event in Nottingham, falling to American CoCo Vandeweghe. She then reached her first singles quarterfinal at a WTA grass court event in Birmingham, where she was beaten by Ekaterina Makarova. She also won the doubles title with Tímea Babos over the world No. 1's, Americans Lisa Raymond and Liezel Huber, her first grass court doubles title. Entering Wimbledon ranked inside the top 70, Hsieh scored her first win at the All England Club in four years by defeating French wildcard Virginie Razzano, who just a month earlier at the French Open became the first player ever to beat Serena Williams in the opening round of a Grand Slam, in straight sets. She followed it up with a win over Stéphanie Fortez Gacon to advance to the third round of Wimbledon for the first time, and beyond the second round of a major for the first time since the 2008 Australian Open. Though she would lose at this stage to then-world No. 1 and recent French Open winner, Maria Sharapova, in straight sets, this marked Hsieh's best performance at a Grand Slam in four and a half years. She also reached the quarterfinals in the mixed doubles tournament, partnering with British player Colin Fleming. Following Wimbledon, she reached a new career-high singles ranking of world No. 56.

In 2006, Hsieh lost in the final qualifying round at the Australian Open to former top-20 player Tamarine Tanasugarn but won her first main draw Grand Slam match en route to the second round in the women's doubles tournament. She was more successful at the next two Grand Slams though. Qualifying to the main draw of the French Open for the first time, Hsieh was defeated in the opening round by local wildcard Mathilde Johansson. She also qualified to her first main draw at Wimbledon, but was beaten in her first match by the 23rd seed Anabel Medina Garrigues, while also losing in the first round in doubles. Hsieh failed to qualify for the US Open, though, falling at the final hurdle to Kirsten Flipkens. She was able to produce much stronger results on the ITF Circuit, reaching two singles and six doubles finals, and winning one singles and four doubles titles respectively.

During the 2001 Australian Open Junior Grand Slam event, Hsieh reached the girls' singles quarterfinals and the round of 16 in the girls doubles event with partner Natalie Ko, losing in two sets to eventual champions, Petra Cetkovská and Barbora Záhlavová-Strýcová. Hsieh displayed stunning results in the 2001 season as a 15-year-old. Playing on the ITF Women's Circuit, she won all of the five events she entered at Wellington, Kaohsiung, Bangkok (twice), and Peachtree City from January until November. Hsieh also competed on her first two WTA Tour events, reaching the semifinals in Bali and the quarterfinals in Pattaya.
