World number nine Sam Stosur has credited hard work for her first-round victory over Kai-Chen Chang.
The Australian has lost matches in Brisbane and Sydney so far this year, while also exiting last year's Australian Open at the first hurdle.
However, the 28-year-old said that she was looking forward to today's match and was happy to advance to the second round.
"It's obviously been a pretty tough summer so far," said Stosur. "But I was looking forward to today.
"I've been working hard so I was glad to come out and get a win.
"I just did what I normally do – get out on the court and practise hard and do the things that usually work for me. It's worked for me everywhere else so it should work here too."
Stosur won the US Open in 2011.
