Johanna Konta outclassed eighth seed Venus Williams 6-4, 6-2 to reach the second round of the Australian Open.
Britain’s number one, 24, raced to victory in 79 minutes as seven-time Grand Slam champion Williams, her left thigh heavily strapped, struggled.
Konta denied that 35-year-old Williams’ age had anything to do with the American’s laboured display.
“It’s irrelevant how old she is because she’s such a champion with so much experience and knowledge,” said Konta.
“Even if she’s playing with one leg out there, you’ve got to really take care of things on your own because she’s an incredible player. I have all the respect for her in the world.”
