This table is current through the 2019 China Open.

On 8 August 2018, Peng was banned for 'coercing her partner' receiving a six months suspension with three months of the ban suspended, and fined $10,000 with $5,000 suspended following an investigation by the Tennis Integrity Unit, for attempting to change her doubles partner by offering the possibility of a financial reward in return for her partner agreeing to withdraw, after the deadline had passed, at the 2017 Wimbledon Championships. Bertrand Perret her coach was also banned for three months.

Peng had a difficult 2015 season. Due to injuries, she had a lot of first round or second round losses. Her best performance of the season was fourth round of the Australian Open, which tied her best performance. As the 21st seed, Peng beat German qualifier Tatjana Maria in the opening round, Magdaléna Rybáriková in the second rond and Kazakh Yaroslava Shvedova, all in straight sets. In the fourth round match, she lost to second seed and the eventual runner-up Maria Sharapova by 3–6, 0–6.

More weirdly, Peng failed to win even one doubles match in 2015. She started the season with her countrywoman and Tianjin teammate Xu Yifan in preparation for the 2016 Olympics, but ended up losing in the first round matches in the Shenzhen Open and Australian Open. Especially, in their first round match in the Australian Open against the 15th seed, Kimiko Date-Krumm and Casey Dellacqua, they wasted a 6–4, 5–0 lead, two match points in the second set and three more in the twelfth game of the final set and eventually lost to their opponents. Peng was particularly frustrated by Xu, who was constantly attacked by their opponents and making a lot of unforced errors, and decided to split the partnership. She played two more tournaments, with Květa Peschke at Dubai and Zarina Diyas at Madrid, but was not able to win a set.

After the first round retirement to Polona Hercog in the first round of French Open, Peng announced the end of her 2015 season due to injuries in her back and waist.

2007 was slightly more successful for Peng than her previous year as she finished ranked within the world's top 50.

After the US Open her ranking climbed up to No. 40, her highest since Wimbledon 2007. Prior to the US Open, Peng reached her first singles final since Strasbourg 2006 at Tier IV Forest Hills Tennis Classic before losing in straight sets to Lucie Šafářová.

The year 2006 began disappointingly for Peng. She lost her first-round ties at Sydney (a tough draw against Ana Ivanovic) and the Australian Open, then withdrew from subsequent tournaments with sickness. As of March 4, she was yet to play again; and the loss of her previous year's ranking points at Sydney and the Australian Open had conspired to displace her to 60th in the world rankings, a moderate decline that cannot reasonably be expected to be irreversible, in view of the tremendous promise she has shown. She has since proven this promise in 2006, reaching the semifinals of a Tier IV tournament in Prague, a final in a Tier III tournament in Strasbourg, third round showing at Wimbledon (including a victory over a top-20 player in Shahar Pe'er, 6–4, 7–6) and finally a successful continuation of her Fed Cup career, winning both her ties against Indonesia.

In January 2005, Peng came through a tough qualifying draw at Sydney comfortably, and went on to reach her first WTA Tour semifinal. On the way, she upset the No. 2 seed Anastasia Myskina in the second round in straight sets, in addition to defeating Camille Pin, Tzipora Obziler, Denisa Chládková and Mashona Washington, all without dropping a set. In the quarterfinal, she was up 6–3, 4–2 against Russian star Nadia Petrova, and well on target for another shock straight-sets victory, when Petrova retired. But Alicia Molik was on top form and finally ousted Peng in the semifinal. The following week, at the Australian Open, the Chinese star finally won her first Grand Slam singles match, defeating Maria Elena Camerin of Italy 6–1, 6–2 before being overcome by Venus Williams in round two.

In August, she topped all her previous achievements by reaching her first Tier I semifinal at San Diego, posting upsets over then world No. 6 Elena Dementieva, world No. 26 Dinara Safina and world No. 7 Kim Clijsters, all in straight sets. Her victory over Clijsters, who was on her way back to being world No. 1 after only a few months back on the tour following injury, ended the Belgian's 26–consecutive-match-winning streak on hard courts. Following the match, Kim told reporters that Peng had the potential to become a top-3 tennis player. Although an inspired Mary Pierce had her way in the semifinal, Peng's outstanding performance in this tournament helped her to her career-best singles ranking (31st) on August 15, 2005, which was also the highest ever singles ranking achieved by any Chinese women's tennis player, improving on the standard set by Li Na, who peaked at 33 earlier the same year (though she may yet ascend to new heights).

By September 2005, Peng ranked among the top-5 female tennis players across the whole Asian continent. That month, she reached two further WTA quarterfinals, at Beijing and (for the second year running) Guangzhou, where she retired in her quarterfinal match against teenaged emerging star Victoria Azarenka after losing the first set by a break. This proved to be her last match of the year; and without being able to defend the points won at Shenzhen the previous November, she found her year-end ranking settling to 35.

In February 2004, she reached her third $25,000 singles event final at Columbus, Ohio, only to be defeated by future superstar Czech Nicole Vaidišová in the tantalisingly close tournament decider, 6–7, 5–7. The following month, she qualified for another $50,000 event, at Orange, California, with wins over Neha Uberoi and Mashona Washington, then defeated Colombian Catalina Castaño and Camille Pin to reach the main-draw quarterfinal, before losing in three sets to Ukrainian Yuliya Beygelzimer. Among further consistent results in ITF tournaments, she was victorious in what was the first ever $75,000 tournament she had entered, defeating Angela Haynes, Yuka Yoshida and Evgenia Linetskaya in straight sets at Dothan to take her sixth career ITF singles title. A month later, she proved this was no accident by winning her second $75,000 event, fending off some tough competition from Lucie Šafářová and Barbora Strýcová en route to a comfortable final victory over Zuzana Ondrášková.

It was not until April 2003 that Peng next won a match; but then she proceeded to put in her career-best performance, coming through qualifying to win her first $25,000 title at Jackson, with match wins against Rika Fujiwara, Tatiana Golovin and Christina Wheeler among others. After disappointing summer results, she started to play more consistently again towards the end of the year; and in December, she won her first $50,000 event, and the fifth ITF title of her young career, at Changsha, with victories over Yuka Yoshida, Yan Zi and Zheng Jie, salvaging her year-end ranking, which had improved only slightly overall to 326, and heralding her coming breakthrough the following year.

In February 2002, Peng won her third $10,000 singles title in the space of nine months at Mumbai, defeating American Sunitha Rao in the final. The following week, she extended her match-winning streak to twelve by coming through qualifying to reach the final of a $25,000 tournament at New Delhi, with wins over Japanese Aiko Nakamura and Austrian Sybille Bammer, before losing in the championship match to Eva Birnerová. In July, she succeeded in qualifying for the main draw of a $50,000 tournament at Lexington; but further success proved elusive, and after a second successive first-round main draw defeat in early August she took nearly seven months off from competition at singles events, ending the year world-ranked just 357.

In 2001, at the beginning of June, aged just fifteen years and four months, she won her first singles title at Baotou, a $10,000 International Tennis Federation (ITF) tournament, after entering as a wildcard, and crushing highly capable countrywoman Sun Tiantian 6–1, 6–4 in the semifinal. In July, she won her second $10,000 tournament of the year (although she was assisted in the final by the retirement of her opponent Liu Nannan after just one game was played, and in the following week's tournament she lost to Liu in the semi-final). Then in October she debuted on the WTA Tour at Shanghai as a wildcard, losing in the first round to Tamarine Tanasugarn.

Peng Shuai (Chinese: 彭帅 ; pinyin: Péng Shuài ; Mandarin pronunciation: [pʰə̌ŋ ʂwâi] ; born 8 January 1986) is a Chinese professional female tennis player. She reached a career-high of world No. 1 in the doubles ranking by the Women's Tennis Association as the first Chinese tennis player (male or female, and in singles or doubles) in February 2014. In August 2011, she peaked at No. 14 of the singles rankings. Peng has won two singles and 22 doubles titles. She won a gold medal at the 2010 Asian Games, defeating Akgul Amanmuradova in the final. At the 2013 Wimbledon Championships, Peng won her first ladies' doubles championship with Hsieh Su-wei of Taiwan and again won at the 2014 French Open with Hsieh. Her best performance at a Grand Slam tournament in singles came at the 2014 US Open when she reached the semifinals, becoming the third Chinese tennis player in history to make a major semifinal after Zheng Jie and Li Na.

This form was not to last as she then failed to win a match in her next six tournaments, including a first round loss at the Australian Open. Peng finally recorded her first win of the year at the Tier II Bangalore Open against Anne Kremer before losing in three sets to Venus Williams, she also won the doubles title with Sun Tiantian. She then upset 23rd seed Karin Knapp to reach the third round at Indian Wells.
