Here's our final preview and prediction.
"I played Brady in the semis of the US Open", Osaka reflected.
Brady, seeded 22th, is in her first Slam final and looking to avenge defeat by Osaka in the US Open semi-finals. "Yeah, it's definitely going to be really tough".
The pair first clashed as juniors in Florida seven years ago when Brady won. I can empathize with Serena and what she's going through.
And she breaks! Osaka hits the net again. "I mean, I was, like, Okay, she's got something special". Brady has held serve almost as effectively as Osaka (.855 to.867) throughout this tournament. That earned a break point - convert that, and she would serve for the opening set.
Next task for Osaka is improving on clay and grass: She's never been past the third round at the French Open or Wimbledon.
"I feel that's where the emotions start - she's probably thinking, what do I need to do now?"
However she quickly recovered as nerves seemed to creep in on the other side, with the Japanese player starting to overplay and spray unforced errors around the court. Osaka's power can be disarming, but Brady knows what to expect after experiencing Osaka's explosiveness beneath the closed roof of Arthur Ashe Stadium.
"I think my returns are better". If Brady can use her forehand to dictate the direction of rallies, she can pull off the upset.
"For her this is a bigger loss, because she is moving better, she is playing better and she is still not really close to Osaka". After beating Serena Williams in the semifinals, Osaka had made her intentions clear: "I have this mentality that people don't remember the runners-up. You might, but the winner's name is the one that's engraved". "I think I fight the hardest in the finals".
And we were like saying: Wow, this girl is really really good, I think she has a chance of getting far here. "It's like the biggest fight".
As well as her previous Grand Slam pedigree, Osaka holds a 20-match winning streak which goes back to early February a year ago. Monica Seles, Serena Williams, Kim Clijsters, Li Na, Angelique Kerber and Caroline Wozniacki have all won the AO after saving a match point. Osaka won when the duo locked horns in the US Open semifinal a year ago.
"I felt like we were both serving pretty well".
"Maybe she was the more aggressive player today". She played, you know, cleaner at times.
Brady, 25, struggled as a junior player. But I think the quarantine process and seeing everything that's going on in the world, for me it put a lot into perspective.
Osaka has now claimed back-to-back Slams twice and she survived a seesaw start to gain control, reeling off six straight games en route to the title.
Where is Aus Open women's final between Brady and Osaka? She will face the pressure to perform, and Brady can take advantage of this by starting off strong.
