(4) Agnieszka Radwanska
After a breakthrough season in 2012, Wimbledon runner-up Radwanska will now have her sights set on landing a maiden Grand Slam title.
The diminutive Pole played the best tennis of her career last season and it came as no surprise when she maintained that form to seal a final date with Serena Williams at SW19.
In doing so, the 23-year-old became the first Polish player to reach a major final in the Open Era, albeit going down 6-1 5-7 6-2 to Williams on Centre Court.
She reached a career-high ranking of No.2 in the world after her Wimbledon exploits, however her form and fitness dipped in the latter stages of the campaign.
Her preparations for the Australian Open have gone well, though, with the Pole dropping just one set in five matches on her way to claiming the ASB Classic in Auckland and then making it two titles in a row with succcess in Sydney, a run which culminated with a 6-0 6-0 win in the final.
Radwanska, whose sister Urszula is also a player on the WTA circuit, has exited the Australian major at the quarter-final stage in each of the last two years, losing to eventual winners Kim Clijsters and Victoria Azarenka on each occasion.
One of the best retrievers in the women's game, Radwanska could well be worth an each-way bet.
