Andrea Petkovic

Petkovic turned professional in 2006 after she finished school, but she had already won four titles on the ITF Circuit. She was the winner of the tournaments in Antalya, Podgorica (both in 2004), Davos and Alphen aan den Rijn (both in 2005).

In April 2007, she became a member of the German Fed Cup team. She played her first Grand Slam tournament at the 2007 French Open where she reached the second round, after coming through the qualifying without losing a set and beating Jarmila Groth. There she lost to later Wimbledon champion Marion Bartoli. After this, and having some success on the ITF Circuit (she won the ITF title in Contrexéville in July 2007), she reached the top 100 of the WTA rankings for the first time. Because of that, she was able to play in the US Open main draw without having to qualify. She once again reached the second round after beating Audra Cohen. In round two she lost to Lucie Šafářová.

At the Australian Open in January 2008, in her first-round match against Anna Chakvetadze, she suffered a cruciate ligament rupture in her right knee after only two minutes of play. This prevented her from playing any tournament for almost eight months, which caused her ranking drop to 465. After the injury, she started playing mostly on the ITF Circuit again where she won a tournament in Istanbul in November 2008. She finished the year with a ranking of 315.

In 2009, Petkovic played her first tournament at the Australian Open due to a protected ranking, where she reached the second round. She mostly kept on playing ITF tournaments until June with success. She won the Open Romania in Bucharest, defeating Jelena Dokić in the semifinals along the way, and regained a top-100 ranking.

In July 2009, Petkovic won her first WTA tournament in Bad Gastein, losing only one set throughout the tournament. In the final, she beat Raluca Olaru.The following week, she reached the semifinals in Istanbul, losing to Lucie Hradecká in three tight sets. After those two weeks, she achieved her then career high singles ranking of world No. 52.

For the rest of the year, she struggled to repeat her success but had another good tournament at the Pan Pacific Open in Tokyo where she came through the qualifying and reached the round of 16. In the second round, she had her win over a top-10 player in beating Svetlana Kuznetsova, but was knocked out by Agnieszka Radwańska.

She played her first tournament in 2010 in Brisbane, Australia, where she reached the semifinal before losing to eventual champion Kim Clijsters. After that tournament, she reached the top 50 of the WTA rankings for the first time.

Petkovic's best singles performance in a Grand Slam event came at the US Open. Her first two matches were three-set upset victories over Nadia Petrova and Bethanie Mattek-Sands. She performed an on-court dance following both triumphs. After she received a third-round walkover due to an injury to Peng Shuai, Petkovic lost her first career Arthur Ashe Stadium appearance to eventual tournament finalist Vera Zvonareva.

Returning to the Brisbane International, and with coach Petar Popović, Petkovic improved on her previous best semifinal appearance by reaching the final, where she lost to Wimbledon semifinalist Petra Kvitová.

Petkovic reached the quarterfinals of the Australian Open, where she was defeated by eventual finalist Li Na, her best achievement in a Grand Slam championship of her career.

Petkovic defeated world number one Caroline Wozniacki in the fourth round at the Sony Ericsson Open in Miami, eventually reaching the semi-finals.

Petkovic won her second WTA Tour title in Strasbourg, defeating Marion Bartoli by retirement in the second set. After that performance, Petkovic reached her new career-high ranking of No. 12 as of 23 May 2011.

As the 15th seed, Petkovic reached the quarterfinals of the French Open.

In August, coach Dušan Vemić joined the team. Petkovic became the sixth German player in history to crack the top 10 by winning her opening match at the Southern California Open in San Diego against American player Alexa Glatch.

At the US Open, Petkovic was seeded tenth. She reached her first ever quarterfinals spot at the US Open against the world No. 1, Caroline Wozniacki. She performed her trademark dance to delight the audience after her fourth round win. On 8 September she lost to Wozniacki.

Seeded ninth at the China Open, Petkovic reached the final, where she lost to Agnieszka Radwańska. It was her last match of the year. She was seeded second at the Linz Open in October but withdrew before the tournament began, citing a right knee injury. In 2011, Petkovic reached her highest ranking alongside her then coaching staff (Popovic/Vemić).

Her first tournament of 2012 was the Brisbane International in January. Seeded second, she reached the quarterfinal before losing to eventual winner Kaia Kanepi. Petkovic then played at the Sydney International the following week, where she lost to Agnieszka Radwańska in the second round. During the match, Petkovic received treatment for what was revealed the following day to be a double stress fracture of her spine and a spinal disc herniation. She explained: "I've been having some back problems for the last three or four months. I've been struggling with it, but I've always believed it was going to be fine and so I pushed through the pain. The last two weeks in Australia I've been having bigger problems and I could only play for 30–45 minutes without pain." As a result, Petkovic withdrew from the Australian Open the following week, where she would have been seeded 10th. The injury ultimately kept her out for three months.

Petkovic made her comeback in a Fed Cup match in April, losing to Samantha Stosur. She then played at the Porsche Tennis Grand Prix in Stuttgart. In her second round match against Victoria Azarenka, Petkovic was down 2–6 and 4–4 when she rolled her right ankle. She was forced out with what was later revealed to be torn ankle ligaments, which required surgery and kept her out for another four months, including the French Open, Wimbledon, and the London Olympics. She said of the injury: "I knew immediately that it was bad because I heard everything crack. I tried to pull my foot up, and it just flopped there. The first thing I thought was: 'Don't cry. Don't cry. Don't cry.' With 4,000 people watching. In Germany." She attended weeks of rehabilitation to rebuild the muscles in her leg, working seven hours a day, five days a week.

Ahead of her return to the tour, Petkovic was worried that she had fallen behind: "I was really scared that I would not be able to compete with the top players and that I might not be able to get back to where I was. Your expectations once you were in the top 10 are to be back in the top 10. Not to be in the top 30 – you're not going to be satisfied with that. I'm definitely scared of that." Petkovic made her second comeback of the year at the New Haven Open in mid-August, reaching the second round. At her next three tournaments, the US Open in August, the Pan Pacific Open in September and the China Open in October, Petkovic was eliminated in the first round, by Romina Oprandi, Petra Martić, and Jelena Janković, respectively. After her defeat in China, Petkovic fell to world rank 192, her lowest since March 2009. She received a wildcard for the Generali Ladies Linz in October, beating Záhlavová-Strýcová in the first round and losing to Ana Ivanovic in the second round. She had much more success in her final two tournaments of the year, reaching the semifinals of the Luxembourg Open and the Royal Indian Open By this time, her world ranking had risen to 126.

Petkovic's final match of 2012 was on 29 December in the 2013 Hopman Cup against Ashleigh Barty. She won the first set 6–4 but appeared to be suffering from a knee injury late on in the set. She received treatment for it before the second set but could not continue and retired from the match in tears.

The injury was identified as a ruptured meniscus in her right knee, the second time in two years she had suffered the injury, and she underwent surgery on it in early January. She said of the injury: "My team and I are actually managing to take it tragically funny... Everything bad that could happen, happened to me. So nothing surprises me anymore. I'm quite relieved it wasn't the ACL because it was a very similar pain and very similar symptoms to what I had in 2008 when I had my ACL torn in Australia. I'm just hoping for a quick recovery. I would so much appreciate if I could be back on court after three or four weeks." Having suffered from a third serious injury in less than a year, Petkovic considered retiring. "I did actually ask for a few internships. I asked a few magazines if I could do an internship. I asked a few politicians that I know if I could do an internship. They all told me you can come whenever you want, and you can stay as long as you want. But I never really wanted."

She returned to the tour in March, having fallen back to world No. 177, entering the qualifiers for the Indian Wells Open and losing in the second qualifying round. Petkovic then received a wildcard for the Miami Masters, where she reached the third round. She also received a wildcard for the Family Circle Cup in April, where she also reached the third round. She was due to face Caroline Wozniacki but withdrew before the match with a calf injury. It had been causing her discomfort since her loss to Tomljanović, so she withdrew as a precaution, noting her recent experience with injuries.

Her next tournaments were the Porsche Tennis Grand Prix in Stuttgart, where she received a wildcard and lost in the first round to Ana Ivanovic; and the Madrid Open in May, where she lost in the first qualifying round to Bethanie Mattek-Sands. She then lost in the second qualifying round of the French Open. After that defeat, her ranking fell back down to world No. 138 and she again contemplated retirement, but her coach didn't take her seriously: "He just laughed and a few days later [I] picked up my racquet again." She then received a wildcard for the ITF Open de Marseille in June, which she won without dropping a set, beating Anabel Medina Garrigues in the final. It was her first tournament win for over two years, her last coming when she won the Internationaux de Strasbourg in May 2011. After the win, she re-entered the world top 100 for the first time since September 2012. She also reached the final of the Nürnberger Versicherungscup that same month, after receiving a wildcard.
