Agnieszka Radwanska has yet to live up to her success of last season when she won three WTA titles to forge her way into the world's top 10, but in such a evenly-matched women's division you can't write anyone off.
An ex-junior Wimbledon champion, she also reached two Grand Slam quarter-finals in 2008 including her impressive run at SW19 where she was knocked out by eventual runner-up Serena Williams.
In fact she seems to have an unfortunate habit of being in the wrong place at the wrong time having also seen her French Open quest dented in the fourth round by Svetlana Kuznetsova, who went on to lift the Roland Garros crown.
The 20-year-old right-hander from Krakow possesses excellent groundstrokes and is expected to one day challenge the game's best on a regular basis.
