Serena Williams has secured a spot in the Australian Open quarter-finals after beating Czech’s Barbora Strycova.
Williams, holder of six Australian Open titles, said it was not her “best day” despite of winning 7-5 6-4.
“[Strycova]’s hard to read, she’s scrappy, gets a lot of balls back. She definitely plays a different game than the other three players I played before,” Williams said.
“I feel like it was really good for me to win on probably not my best day, which is always good, because sometimes you rely on one shot and if it goes off, and then, like, what happens now?
“It was really good for me to almost lose that so I know my other game is going pretty good, too.”
The 35-year-old is set to play against Britain’s Johanna Konta, who defeated Russia’s Ekaterina Makarova 6-1 6-4 on Monday.
“I watch [Konta’s] game a lot,” said Williams. “She’s been doing really, really well. She has a very attacking game and I look forward to it.”
Konta said Williams was “the greatest player to be playing right now. She has pretty much done it all in our sport and very few people get to do that in whatever discipline they do.
“I have never been on court with her, so I am looking forward to the challenge and looking forward to competing, and really going out there and trusting in my own system and trusting in the good things that I bring to the court.”
