A former top-five player in both singles and doubles, she reached a career-high ranking of No. 3 in the world in both disciplines (doing so in doubles on 21 March 2005, then in singles on 15 May 2006). Petrova won a total of 37 titles on the WTA Tour in her career, 13 in singles and 24 in doubles, as well as over $12.4 million in prize money, making her one of the most successful Russian tennis players of all time.

Petrova's career highlights in singles include reaching a total of nine Grand Slam quarterfinals across all four major tournaments (including two Grand Slam semifinals at the French Open in 2003 and 2005), and qualifying for the WTA Tour Championships on three separate occasions. Her largest singles titles came at two Tier-I tournaments, Charleston and Berlin in 2006 (during a span in which she won three consecutive tournaments and a career-best 15 matches in a row), one Premier 5 title in Tokyo in 2012, and winning the year-end Tournament of Champions in 2012. From June 2003 to September 2013, Petrova was continuously ranked inside the top 30 (a period of 538 weeks), was inside the top 20 for over 500 of them, and spent over 150 weeks ranked inside the top 10. Over a 10 year period from 2003 to 2012, she finished the year ranked inside the top 30 on every single occasion, and inside the top 20 in all of them except 2011.

Equally successful in doubles, Petrova's career highlights included winning the year-ending WTA Championships twice, with Meghann Shaughnessy in 2004, and with compatriot Maria Kirilenko in 2012. With Kirilenko, she also won the bronze medal in the doubles competition at the 2012 Summer Olympics. She also reached two Grand Slam finals in doubles, doing so at the 2010 US Open with Liezel Huber and the 2012 French Open with Kirilenko. She also won a total of nine Tier I/Premier Mandatory titles (including three in Miami in 2004, 2012 and 2013), was a seven-time Grand Slam doubles semifinalist, a twenty-time Grand Slam quarterfinalist, and finished with a year-end top-ten ranking four times.

Petrova announced her retirement from professional tennis on 11 January 2017 at the age of 34, due to a multitude of injuries. and a nearly three-year absence from the tour (she played her last professional match in April 2014).

Early life
Petrova was born in Moscow. Her father Viktor was a hammer thrower, while her mother Nadezhda Ilyina won a bronze medal at the 1976 Montreal Olympics in the 400 meter relay. Her father is still an athletics coach, and her mother was an athletics coach until her death in 2013. As a child, Nadia did a lot of travelling around the world with her parents. She eventually settled in Egypt, where she trained with Mohammed Saif and her parents.

Playing style
Petrova is an all-court aggressive player who is capable of hitting winners off both wings, but particularly off her back-hand and which she hits flat and with slice. Nadia's weaknesses are her movement and exhibiting mental fragility during key points in highly contested matches.

Early years
As a junior, Petrova won the 1998 French Open, beating Jelena Dokić in the final. The same year, she finished runner-up at the Orange Bowl to Elena Dementieva and she also finished runner-up at the junior event of the 1999 US Open to Lina Krasnoroutskaya. In May 1998, she played her first WTA tournament at the J&S Cup as a wildcard entrant. She also received a wildcard for her home event in Moscow, the Kremlin Cup, where she picked up her first top-20 win over Iva Majoli. By the end of 1999, Petrova had reached the top 100.

In 2000, she reached the third round of the Australian Open and the quarterfinals of the Miami Open, beating Julie Halard-Decugis for her first top-ten win before losing to Lindsay Davenport. She finished the season at No. 50. She reached the fourth round of both French Open and the US Open in 2001 and her ranking hit a high of No. 38 during the season. Petrova also broke through in doubles in 2001, winning her first two WTA titles in Rosmalen and Linz (the latter of which alongside Dokic, by then a top-10 player). However, her 2002 season was marred by injuries causing her singles ranking to drop out of the top 100. During this time, Petrova mainly focused on doubles, reaching the semifinals of the US Open with Nicole Pratt, two Tier I finals in Moscow and Zurich with Dokic, and reaching the top 20.

2003–2004: First Grand Slam singles semifinal, doubles prominence, and top 10 rankings
At the 2003 Australian Open, Petrova defeated Gréta Arn 6–2, 6–1 and then upset 21st seed Ai Sugiyama 6–4, 6–4 in the second round. She then lost to world No. 15, Patty Schnyder, 2–6, 6–4, 3–6 in the third round.

Petrova was ranked world No. 76 going into the French Open. In the first round, she beat the three-time champion and world No. 12, Monica Seles 6–4, 6–0, on what was to be Seles' last professional match. She then defeated Silvija Talaja 6–1, 6–1 and Marissa Irvin 6–1, 6–1 to reach the fourth round. Here, Petrova stunned seventh seed and 2001 French Open champion Jennifer Capriati, 6–3, 4–6, 6–3. In the quarterfinals, she won again in three sets over 21st seed Vera Zvonareva 6–1, 4–6, 6–3 to reach her first ever Grand Slam semifinal. Petrova faced world No. 2, Kim Clijsters, and despite having a set point in the first set, Petrova was beaten in straight sets 7–5, 6–1. However, her ranking increased to world No. 30.

Petrova reached the semifinals of Rosmalen, defeating Elena Dementieva en route but lost to world No. 3, Justine Henin, in three sets.

The following week in Linz, Petrova beat Paola Suárez and Patty Schnyder to reach her first WTA Tour singles final. However, she fell to Ai Sugiyama 5–7, 4–6. Petrova ended 2003 ranked world No. 12, with a 45–23 singles record.

Petrova reached her second WTA singles final at Gold Coast, losing once again to Sugiyama 6–1, 1–6, 4–6. Although seeded 10th at the 2004 Australian Open, she was upset in the first round by Anikó Kapros, losing 3–6, 3–6.

In March 2004, she entered the top 10 singles rankings after reaching the semifinals of the Tier-1 Miami Open, climbing to No. 9 in the world. She reached the semifinals at Amelia Island, beating second-seeded Serena Williams before losing to Lindsay Davenport. After this, her ranking elevated to a career high of No. 7. However, she failed to defend her semifinal points from the 2003 French Open, losing to Marlene Weingärtner in the third round, 3–6, 2–6. Petrova fared slightly better at Wimbledon, reaching the fourth round before losing to Capriati.

At the US Open, she pulled off the biggest win of her career by defeating world No. 1 and defending champion, Justine Henin-Hardenne, 6–3, 6–2 in the fourth round. It was Petrova's first victory over a world No. 1. She lost in the quarterfinals to eventual champion Svetlana Kuznetsova, 6–7, 3–6.

Petrova reached the semifinals of Linz, losing to Elena Bovina in three sets, before reaching the semifinals of Philadelphia, losing to Vera Zvonareva. She finished the year ranked world No. 12 in singles (with a 40–25 record) but qualified for the WTA Championships in doubles for the first time with Meghann Shaughnessy after a season that saw the pair win six doubles titles (including three at Tier I level). The pair defeated the second seeds Kuznetsova and Elena Likhovtseva in the semifinals, then beat Cara Black and Rennae Stubbs to win the title, the biggest of Petrova's career. As a result of her doubles success in 2004, she finished the year inside the top 10 for the first time at world No. 7.

2005: Second French Open semifinal, first career singles title, and top 10 finish
Petrova reached the fourth round of the Australian Open, losing to the eventual champion Serena Williams, in three sets. Over the next two months, her best result was a semifinal appearance at the Open Gaz de France. In doubles, she reached the final at Indian Wells with Meghan Shaughnessy, where they lost to Paola Suárez and Virginia Ruano Pascual. Following Indian Wells, Petrova rose to her career-high doubles ranking of No. 3 in the world.

After making the semifinals in Amelia Island and the quarterfinals in Charleston, Petrova reached her third career final (and first at Tier I level) at the German Open in May, beating Mary Pierce, Amélie Mauresmo and Jelena Janković, before losing to Justine Henin-Hardenne. This performance lifted her ranking to No. 9, starting a two-plus year period of continuously being ranked inside the top 10.

At the French Open, Petrova defeated 17-year-old Ana Ivanovic in the quarterfinals before losing to Henin-Hardenne 6–2, 6–3 in the semifinals; her performance at the tournament saw her ranking rise to world No. 8. She also reached the semifinals in doubles with Shaughnessy, but the pair would split shortly afterwards to Shaughnessy's multiple injuries. A few weeks later at Wimbledon, she reached the quarterfinals before losing to defending champion Maria Sharapova, 6–7, 3–6. After Wimbledon, she was defeated in the quarterfinals of the next five tournaments she entered. This included the events in Los Angeles, Toronto, Luxembourg, and Filderstadt. Between Toronto and Luxembourg, Petrova also competed at the US Open, where she made her third consecutive Grand Slam quarterfinal. However, she was beaten by Sharapova (the new World No. 1) in straight sets for the second time in a row at Grand Slam level.

After losing the final in Bangkok to 16 year-old Nicole Vaidišová, Petrova finally won her first singles title on her fifth attempt at the Generali Ladies Linz (where she had reached her first ever WTA final in 2003) with a comeback three-set win over Patty Schnyder in the final. Her successful singles season meant she qualified for the WTA Championships in Los Angeles. She thrashed Maria Sharapova 6–1, 6–2, but lost here other two singles matches to Patty Schnyder and Lindsay Davenport meaning she exited at the round robin stage. She ended 2005 ranked world No. 9 (her first top-10 finish) and a 56-22 record, a career-high single season wins total.

2006: Five singles titles, Top 3 ranking in both singles and doubles
At the Australian Open, Petrova was seeded sixth and defeated Sophie Ferguson, Martina Müller, Maria Elena Camerin, and Elena Vesnina on her way to her first quarterfinal at the Australian Open, the only major in which she had not yet advanced to that round. She lost to fourth-seeded Maria Sharapova, 6–7, 4–6 in the quarterfinals.

At the Qatar Open, Petrova picked up her first title of the year and second overall by beating second-ranked and top-seeded Amélie Mauresmo, 6–3, 7–5, in the final. The victory took her ranking to No. 7. She followed it with a quarterfinal showing at the NASDAQ-100 Open, losing to Mauresmo, 3–6, 1–6.

Petrova then began a run that would take her to three titles, winning fifteen straight matches. At Amelia Island, she defeated Francesca Schiavone in the final to pick up her third career title. One week later, she won her second consecutive title and the biggest of her career in Charleston with a victory over Patty Schnyder. This was Petrova's first Tier I title.

She next entered the German Open in Berlin, defeating Justine Henin-Hardenne in three sets for her fifth career singles title, her third consecutive singles title, and her second consecutive Tier I title. With this win, Petrova extended her winning streak to a career-best 15 matches and ascended to her career-high singles ranking of world No. 3.

However, despite being one of the favorites for the French Open, Petrova suffered an ankle injury during training just days before the start of the tournament and was upset in the first round by Akiko Morigami, 2–6, 2–6. This marked the first time Petrova lost in the opening round of a Grand Slam since the 2004 Australian Open – Women's singles, snapping her 15-match winning streak, as well as her streak of four consecutive Grand Slam quarterfinals. Petrova's injury forced her to later withdrew from Wimbledon. Her return a few weeks later went poorly as she did not win a match in the US Open Series, going 0–3. During this time, however, she won her first doubles title since the 2004 WTA Championships at the Tier I Canadian Open, alongside the great Martina Navratilova. More significantly, this was the 177th and final WTA doubles of Navratilova's career (an all-time record) before her permanent retirement at the end of the year. The US Open went poorly, however, as Petrova was upset in the third round by French teenager Tatiana Golovin.

After winning just one match in her next two tournaments, Petrova rebounded by winning the Porsche Tennis Grand Prix. She avenged her loss at the US Open to Golovin by beating the 18-year old in straight sets to earn her fifth title of the year and her first since the ankle injury. She then continued her return to form by reaching her seventh singles final of the year at the Kremlin Cup in Moscow, losing to compatriot Anna Chakvetadze.

At the WTA Championships in Madrid in November 2006, her lone victory was over top-ranked Amélie Mauresmo, 6–2, 6–2. She finished the year at No. 6 (her best ever year-end ranking) and a 48-19 match record.

2007: Dip in form
At the Australian Open, Petrova reached the third round, before falling to Serena Williams, the eventual champion, after holding a 5–3 lead in the second set.

At the Open Gaz de France in Paris, Petrova picked up her seventh career tour title and first of the season by beating Lucie Šafářová. Petrova reached the quarterfinals in Key Biscayne, losing to Justine Henin. Petrova then reached the final in Amelia Island where she was the defending champion, but lost to Golovin. After choosing not to compete in Charleston, Petrova failed to defend her title in Berlin, losing to Svetlana Kuznetsova in the quarterfinals, before retiring from her third-round match at the Italian Open due to low back pain.

She was the eleventh-seeded player at the French Open, but was upset by Květa Peschke, 5–7, 7–5, 0–6. After the loss, she claimed that the lower-back pain sustained in Rome had been bothering her. It was her second consecutive first-round loss at the French Open because of an injury. At Wimbledon, Petrova lost to 19 year-old Ana Ivanovic 1–6, 6–2, 4–6 in the fourth round.

In the 2007 Fed Cup tie against the USA in July, Petrova played a pivotal role in securing the victory for her team. While losing on the first day against Venus Williams, she won her singles match against Meilen Tu on the second day, and then teamed with Elena Vesnina to beat Williams and Lisa Raymond in the decisive doubles rubber.

At the LA Championships, Petrova reached her third final of the year, losing to Ana Ivanovic in straight sets. At the US Open, Petrova was seeded seventh, but lost to Ágnes Szávay in the third round, 4–6, 4–6. The loss meant that she had not gone past the fourth round of any Grand Slam tournament all year, the first time since 2002.

She finished 2007 ranked No. 14, her lowest year-end ranking in five years.

2008: Wimbledon Quarterfinal, multiple titles
Petrova started her 2008 season on a two-match losing streak going into the Australian Open, losing in the first round in Gold Coast as the second seed to Tathiana Garbin, 7–5, 5–7, 3–6, and in Sydney 5–7, 3–6 to Sybille Bammer. She still managed to reach the fourth round of the Australian Open though as the 14th seed with wins over Nicole Pratt, Anne Kremer, and Ekaterina Makarova, all in straight sets. There she played Agnieszka Radwańska, who beat her 6–1, 5–7, 0–6. Petrova held a 6–1, 3–0 lead and looked to be on her way to an easy victory. In the third set, she won just four points.

Petrova's injuries continued to strike -when she was forced to retire in the second round of Miami with a right quad strain while trailing 1–2 in the first set against Zheng Jie.

At the German Open in Berlin, Petrova returned to action as the 16th seed and defeated Katarina Srebotnik, 7–6, 3–6, 7–6, in the first round, before losing in the second round to Maria Kirilenko, 3–6, 3–6. As a result, she dropped out of the top 20 for the first time since August 2003. Petrova was once again defeated by Kirilenko in the first round of Rome, but this time in three sets, 6–3, 5–7, 4–6. At her final warm-up tournament in Istanbul, Nadia was seeded third and got past Lilia Osterloh in the first and Marta Domachowska in the second round. She lost to Akgul Amanmuradova, 6–7, 6–1, 4–6, in the quarterfinals.

These losses put Petrova in poor stead going into the French Open. As the 25th seed, she beat Aravane Rezaï and Alisa Kleybanova in straight sets, before being thrashed by Svetlana Kuznetsova in the third round, 2–6, 1–6.

Petrova's grass-court season began at Eastbourne, where she reached her first final of the year showing good form. She was beaten in a close match by Pole Agnieszka Radwańska, 4–6, 7–6, 4–6.

At Wimbledon, Petrova was 21st seed and was on track after wins over Olga Govortsova and Mara Santangelo. Petrova then pulled off an excellent win over the in-form teenager and 16th seed Victoria Azarenka in the third round. In the fourth round, she faced unseeded Alla Kudryavtseva who just came off a win over third seed Maria Sharapova; Petrova won to reach her second quarterfinal at Wimbledon, and her seventh at Grand Slam level. This was also the first time that Petrova had reached a Grand Slam quarterfinal since the 2006 Australian Open. She lost a tough two and a half hour marathon match against the fifth seed Elena Dementieva, 1–6, 7–6, 3–6. Petrova rallied from 6–1, 5–2 down and saved match points throughout the second set, but eventually lost the match in the third set. Her ranking improved to world No. 17 after the tournament.

Bouncing back from a first-round defeat at Stanford to Dominika Cibulková, Petrova reached the quarterfinals at Los Angeles, defeating fifth seed Zvonareva en route, before losing to Janković, 5–7, 4–6. At Montreal, she again suffered a surprise defeat by Cibulková in the third round, this time losing 6–7, 2–6.

Nadia then played in Cincinnati, as she did not gain entry into the Beijing Olympics because she was not in the top-four ranked Russian players at the time. After easy wins over Galina Voskoboeva, Julie Ditty, and Lilia Osterloh, Petrova once again found herself up against Maria Kirilenko for a place in the final. This time though, Petrova was victorious, coming back from a set down to win, 1–6, 6–2, 6–1. Petrova then thrashed Nathalie Dechy, 6–2, 6–1, in the final to win her first singles title of the year, the eighth of her career, and her first since February 2007. She also won the doubles title in Cincinnati, partnering with Kirilenko, beating Hsieh Su-wei and Yaroslava Shvedova in the final in a third-set tiebreak. This marked Petrova's 13th career doubles title and her first in two years.

Petrova was in good form heading into the final Grand Slam tournament of the year at the US Open, where she was seeded 19th. She handidly beat Olivia Sanchez in the first round and Hsieh Su-wei in the second but was ousted, 4–6, 6–4, 6–3, by the 16th seed Flavia Pennetta in the third round.

Petrova bounced back to good form at the Bali Tennis Classic. Seeded fourth, Nadia defeated fifth seed Francesca Schiavone in the quarterfinals, but she lost in the semifinals to second seed and eventual champion Patty Schnyder, 5–7, 1–6.

At the Pan Pacific Open in Tokyo, Petrova was unseeded, but beat two top–10 players, Ana Ivanovic, the second seed in the second round, and Agnieszka Radwańska to reach the semifinals, where she lost 1–6, 0–6 to Dinara Safina, the eventual champion. In the doubles tournament with Vania King, the duo managed to beat three out of the four seeded teams to win the title. Two weeks later in Stuttgart, she reached her third final of the season, after an impressive run, beating Barbora Záhlavová-Strýcová, Patty Schnyder, Li Na, and Victoria Azarenka in straight sets. She failed to win the title, this time losing to Jelena Janković, the world No. 2, 4–6, 3–6. Despite not winning the title, Petrova's ranking moved back into the top 15 to world No. 14 as a result of reaching the final.

Petrova was a quarterfinalist at her home event, the Kremlin Cup in Moscow, beating teenager Caroline Wozniacki, before losing to compatriot and third seed Elena Dementieva, 4–6, 6–4, 6–7. However, she won the doubles title (her third of the season) with Katarina Srebotnik as the pair defeated the defending champions, Cara Black and Liezel Huber, in the final. She was also a quarterfinalist in Linz, losing 3–6, 2–6 to Radwańska.

At her final tournament of the season in Quebec City, Petrova won her second title of the year (and ninth of her career), beating lucky loser Angela Haynes in the semifinals and Bethanie Mattek-Sands, 4–6, 6–4, 6–1, in the final. This title also secured her status as the second alternate for the Tour Championships should a second player withdraw. This did indeed happen, and Petrova came in replacing Serena Williams, who pulled out after her second round-robin with a stomach injury. She lost her only match to Dementieva, 4–6, 6–4, 4–6.

Petrova finished the 2008 season ranked world No. 11 with a 47-24 match record.

2009: Poor results
Petrova started 2009 playing at the Sydney International, where she was seeded seventh. She lost in the first round to Alizé Cornet, 2–6, 4–6. Petrova was seeded tenth at the Australian Open in Melbourne. She lost to seventh–seeded Vera Zvonareva in the fourth round, 5–7, 4–6. Nevertheless, because of defending champion Maria Sharapova's absence due to shoulder surgery and Ana Ivanovic's third round loss, Petrova's ranking moved back inside the top 10 for the first time since early 2007.

Petrova did not play in the Indian Wells, a Premier Mandatory event due to injury. In Miami, Nadia entered as ninth seed, but lost to world No. 54, Ekaterina Makarova, in the third round, 5–7, 1–6.

Petrova next headed to Ponte Vedra Beach as the top seed, where she defeated Olga Govortsova, Madison Keys (who had just won her first main-draw match), and Alona Bondarenko. She fell in the semifinals to eventual finalist Aleksandra Wozniak, 4–6, 6–4, 2–6. Petrova fell in the second round at Charleston to Melinda Czink, but won the doubles title partnering Bethanie Mattek-Sands. At the Porsche Tennis Grand Prix, Petrova was seeded sixth, but lost in the second round to Flavia Pennetta, 2–6, 2–6. Despite the poor singles result, she did well in doubles once more, winning the title with Mattek-Sands. She next went to the Rome Masters as eighth seed, where she had a first-round bye before defeating giant-killer Carla Suárez Navarro. In the third round, Petrova was ousted by María José Martínez Sánchez, 4–6, 7–6, 4–6.

Petrova's next tournament was Wimbledon, the third Grand Slam of the year, where she was the tenth seed. She beat Anastasiya Yakimova in the first round. Petrova won her second-round match against Shahar Pe'er, and then came from a set down to beat Gisela Dulko. Petrova lost to Victoria Azarenka in three sets in the fourth round.

Petrova began her US Open Series campaign at Stanford, where she was seeded fifth. After defeating her doubles partner Bethanie Mattek-Sands in three sets in the first round, Petrova lost again to Sharapova, 1–6, 2–6, in just over an hour. In Los Angeles, she was also seeded fifth, but lost to tenth seed Flavia Pennetta, 3–6, 3–6, in the third round. Petrova then headed to Cincinnati, where she was the defending champion and the tenth seed. She was unable to defend her title, losing in the first round to Alona Bondarenko, 2–6, 3–6. This caused her ranking to slip out of the top 10 (where she had been since the end of the Australian Open) to world No. 12. Petrova next played in Toronto as the tenth seed, where her poor form continued as she fell again to Maria Sharapova in the first round. Continuing her campaign on the US Open Series, she then received a wildcard as the fourth seed at the New Haven, but again lost to compatriot Anna Chakvetadze in the first round.

Her next tournament was the final Grand Slam of the year, the US Open. Petrova was the 13th seed and defeated Katarina Srebotnik and Julie Coin in the first and second round in straight sets. Petrova then got past world No. 22, Zheng Jie. Petrova was defeated in the fourth round by the 17 year-old unseeded American Melanie Oudin, 6–1, 6–7, 3–6. However, her ranking improved one spot to world No. 12.

Petrova then headed to Quebec to defend her title at the Bell Challenge. Petrova was the top seed and advanced to the quarterfinals with wins over Carly Gullickson and Madison Brengle in straight sets. Here, Petrova faced fifth seed Melinda Czink and was a set down when she was forced to retire due to a viral illness. Czink would go on to win the title. However, Nadia quickly returned to action in Tokyo as 13th seed, but continued a dismal season, losing in the second round to Magdaléna Rybáriková, 2–6, 2–6. She slipped to world No. 17 as a result of this bad form. Nadia then participated at China Open, where she was 13th seed. She beat her compatriot Alla Kudryavtseva in the first round and world No. 24, Daniela Hantuchová in the second round. She played one of her best matches in 2009 by beating Serena Williams in a thriller three-set match in the third round, despite the fact that Williams was just about to snitch back the world No. 1 ranking from Dinara Safina the following week. Petrova then survived another three-setter against Peng Shuai in the quarterfinals. This was only Petrova's second semifinal of the year, but she lost to the reigning French Open Champion, Svetlana Kuznetsova, 1–6, 3–6.

Petrova then competed in the Kremlin Cup in both singles and doubles. Seeded fifth, she defeated Yana Buchina in the first round, but fell to Alona Bondarenko in the second round. Alongside Maria Kirilenko, the pair won the doubles title by beating Maria Kondratieva and Klára Zakopalová in the final. This was her third doubles title of the season (all at Premier level), her third Kremlin Cup title, and the 18th of her career.

Petrova finished her poor year with a 30–21 singles record and ranked world No. 20. It was by far her worst year on tour as she captured no singles titles for the first time since 2004, and failed to reach at least one final for the first time since 2002. Her highlights of the year are reaching the semifinals in Ponte Vedra Beach and Beijing and reaching the quarterfinals in Quebec City.

2010: Two Grand Slam singles quarterfinals, First Grand Slam doubles final
Her year started at the Brisbane International in Australia. After drawing comeback queen Justine Henin, Petrova lost in a close 5–7, 5–7 match. She then competed in the Sydney International, but lost again in the opening round to 39-year-old Kimiko Date-Krumm, 3–6, 7–5, 4–6.

Seeded 19th at the Australian Open, Petrova reached the third round by defeating Edina Gallovits and Kaia Kanepi. In the third round, she caused a huge upset by mothballing 15th seed Kim Clijsters 6–0, 6–1 in just 52 minutes. Clijsters, who had won the 2009 US Open in just her third tournament after coming back from retirement, was the bookmaker's second favourite to win the tournament. Petrova followed that with another upset in the fourth round over third seed and 2009 French Open champion Svetlana Kuznetsova. This was the second time in her career that she had reached the quarterfinals at the Australian Open. She fell to former world No. 1 and eventual runner-up Justine Henin (who had just come out of retirement herself), 6–7, 5–7, in a tight match after leading 3–0 in the second set.

After a first-round defeat to Stefanie Vögele in Dubai, Petrova next competed at the Premier Mandatory events in Indian Wells and Miami. At Indian Wells, Petrova was seeded 16th. After receiving a bye to the second round, she dispatched Patty Schnyder and then Peng Shuai, before losing in the fourth round to second seed Caroline Wozniacki, 3–6, 6–3, 0–6. At the Miami Open, Petrova was again seeded 16th, but fell in the third round to 19th seed Daniela Hantuchová, 2–6, 4–6. She also played doubles with Samantha Stosur in both tournaments. The pair was able to reach the finals of both events, but could not come away with the elusive Sunshine Double, falling to Květa Peschke and Katarina Srebotnik at Indian Wells and Gisela Dulko and Flavia Pennetta in Miami. Nevertheless, these results brought Petrova back into the top 10 in doubles for the first time since August 2005.

Petrova began her clay-court season in Charleston and won her first two matches in straight sets against Vania King and Aleksandra Wozniak, before losing to Wozniacki in the quarterfinals. Partnering with Liezel Huber for the first time at this tournament, the duo won the title over Vania King and Michaëlla Krajicek.

On the red clay, Petrova was seeded 14th at the Italian Open.
