(5) Sam Stosur
- DOB: 30/03/1984
- Nationality: AUS
- Became Pro: 1999
- Height: 1.72
Another of last season's big improvers, Stosur starts as the home nation's big hope for success in 2011.
No Aussie has won a singles title at the Australian Open since Chris O'Neil claimed the women's crown in 1978.
However, Stosur holds decent claims after a 2010 campaign which saw her reach the French Open final and move into the world's top 10.
Showed her hardcourt prowess with a run to the quarter-finals of the US Open and will now be confident of going beyond the last 16 of her home Slam for the first time.
Possesses the game's best kick-serve, while her forehand is also a big weapon.
Cannot be ignored in the title shake-up.
