Brady, remarkably unaffected by losing two weeks' practice while placed in hard lockdown upon her arrival in Australia, will play in her first Grand Slam singles final when she faces Osaka on Saturday at 12:30 a.m. PST.
With two U.S. Open wins, Osaka has won all of her Grand Slam trophies on hardcourts but Fissette said success on Wimbledon grass and French Open clay was just a matter of time.
The sweeping win confirms Osaka's status as tennis's leading light having brushed aside Williams in straight sets in the semi-finals. The feature of Williams-Osaka semifinal battle was the number of service breaks throughout the match.
And she had a warning for the 22nd-seeded American Brady ahead of the final. "I think she was just coming up, maybe inside the top 200, and I remember playing her", Brady said. I think that's where you sort of set yourself apart.
In Saturday's final, Osaka will lock horns against American Jennifer Brady. In a tantalizing three-set contest, the Japanese woman got better of the American, 7-6 3-6 6-3. It's the other person [who] won as many matches as you did. "I think it was a pretty high-quality match from both of us".
"I think my returns are better. I can't fully base everything on that match, but definitely it's something to reference".
"She's such an fantastic champion that inspires both male and female athletes around the world".
The last obstacle between Osaka and her second Australian Open title is Brady, who subdued nerves to pull out a 6-4, 3-6, 6-4 semifinal victory over Karolina Muchova of the Czech Republic.
"I remember playing her, I was, like, "Wow, she hits the ball huge".
"She knows the experience of the past years. when her attitude is good, her mind is very clear what she needs to do", Fissette told reporters.
That was part of the six-game run that put Osaka ahead 4-0 in the second and she was on her way.
Brady, seeded 22th, is in her first Slam final and looking to avenge defeat by Osaka in the US Open semi-finals. She was one of the 72 players in full quarantine after someone tested positive on her flight.
"But there are going to be moments where I'm going to be thinking "wow, this could be my first Grand Slam title". "Wow, this could be my first Grand Slam title".
Osaka is more experienced on the highest stage despite being two years younger and has changed her attitude to big-match occasions. I can empathize with Serena and what she's going through. I mean, there is no doubt, athletes, not just tennis player.
