No one is more surprised than German player Andrea Petkovic that she has got into the second week of the 2011 Australian Open beating the likes of Maria Sharapova.
She is used to winning with 8 ITF and 1 WTA Singles to her name, plus 3 doubles, but when she is faced with Venus Williams it is understandable she thought she wouldn't survive another round.
But she had played just 7 points when Williams doubled up in pain, called for the trainer and then decided she had to retire due to the muscle injury she sustained in the previous round.
She then faced the only former champion left in the tournament, Maria Sharapova who knocked out Julia Georges. With Justin Henin losing to Svetlana Kuznetsova the women's competition was wide open.
Petkovic began playing tennis at the age of 6 years-old when her father Zoran Petkovic, a former Yugoslavian Davis Cup Player, first took her to play tennis. He still coaches her along with Petar Popovic, and travels with her.
Her father never pushed her into turning professional and she finished high school before competing on the pro circuit full time. She graduated on 2006 with an Abitur from the Georg-Buchner-Schule in Darmstadt and she has been studying Political Science at the Distance University of Hagen since 2008. She likes to educate herself by reading and her favourite authors are Goethe and Oscar Wilde, and she speaks German, English, French and Serbian/Bosnian.
She turned professional in 2006 after leaving school, but by then she had already won 4 ITF titles in Antalya, Podgorica, Davos and Alphen aan den Ryn.
Since the beginning of her professional career she keeps a diary at irregular intervals about her life on the WTA Tour in the Frankfurter Allgemeine Zeitung, a big German newspaper. She obtained German Citizenship in 2001 as she has lived there most of her life.
She is currently the German Number 1 and was German National Champion in 2007 and 2009. She played for Germany in the 2007 Federation Cup and the same year competed in her first French Open reaching the 2nd round having come from the qualifying competition without losing a set.
In the 2008 Australian Open she suffered a cruciate ligament rupture of her right knee in her first round match against Anna Chakvetadze only two minutes into the match.
She was out of action 8 months and when she returned she played mostly on the ITF circuit and won a tournament in Istanbul. In 2009 she played her first tournament at the Australian Open due to a protected ranking but lost in the second round to Alize Cornet.
She played mostly ITF tournaments after that with a lot of success to get her ranking back into the Top 100.
In 2010 her best singles performance came at the US Open where she created two upsets in the first and second rounds beating Nadia Petrova and Bethanie Mattek-Sands respectively. She lost to the eventual tournament finalist Vera Zvonareva.
At the Brisbane International 2011 Andrea Petkovic reached the Final but lost to Wimbledon semi-finalist Petra Kvitova.
