Wozniacki had a very easy path through the first round, defeating inexperienced wildcard Chelsey Gullickson for the loss of just two games. After all the hype surrounding her chances of winning the title her, she was simply glad to get on court and get on with the tournament.  The top seed got the benefit of a night match but today she gets her first taste of the brutal heat which has already proved too much for many players.

18 year old Kai-Chen Chang is at a career high of 84 but 2010 has not been a particularly sterling season for her with the highlight, a solitary quarter-final in Kuala Lumpur. However her counter-punching style is effective in the heat and it helped her wear down Carla Suarez Navarro 6-2, 6-4 in the opening round.

Wozniacki beat Chang 6-4, 6-3 at Wimbledon which will be a confidence boost going into the match.
