World number one Ashleigh Barty was happy to come through a tough second-round match with Anna Blinkova at Wimbledon despite not being at her best.

The 25-year-old struggled on serve in a 6-4 6-3 win where she was broken twice in the first set before she fought back to triumph in one hour and 30 minutes.

Eventually Barty's class and attacking intent paid dividends as she reached round three at the All England Club for a third straight tournament despite nine double faults which were put down to "a few technical things" by the Australian.

Since Barty flourished at Wimbledon in 2015 to seal the junior competition, she has been earmarked as a future winner of the Championships and the stars are starting to align having made the fourth round only once before two years ago.

Rivals Naomi Osaka and defending champion Simona Halep were already absent from the main draw while Serena Williams and third seed Elina Svitolina have exited the competition this week.

But Barty insisted her full focus is on Siniakova, who she has never faced in a singles match, and not the opportunity starting to present itself as she looks to remain in the hunt for a second grand-slam title.

"It is not something I can control," she said. "Speculating now is a waste of time and it is certainly something I am not going to do, to be looking at the draw. I never have and never will.

"Obviously those that are injured, I really hope they get healthy and they are out playing soon so it is a waste of time to think about that.

"I feel good and it is certainly nice to have another opportunity in the third round here at Wimbledon.

"I am looking forward to another challenge of facing Katerina, it is a tough one but I am looking forward to it.

"It is different challenges against every opponent and all I can do is prepare for that opponent as best I can and see what happens."
