The Australian was ranked number one, of course, a position she's held now for 83 weeks. But right behind her was Karolina Pliskova, her opponent tonight and herself a former world No.1.
Pliskova may not have won a grand slam tournament, but she knows all about the big occasions, having faced Angelique Kerber in the final of the 2016 US Open.

For Barty, there's the expectation of a hopeful nation. The fact no Australian woman has lifted the Wimbledon trophy in 41 years has been well documented.
But for former World No.4 Jelena Dokic, it's just a matter of when, not if, Barty adds to her 2019 Roland Garros title.
"I've always thought Ash will be a multiple grand slam champion, she can win on different surfaces," Dokic told Wide World of Sports.
"We've always thought she could do well at Wimbledon because her game suits the grass, she won the junior title here 10 years ago, and now we're seeing it come through.
"She's already won on clay, and on hard courts it's only a matter of time before she goes all the way at an Australian or US Open as well.
"Regardless of what happens against Pliskova, I see Ash winning more slams, there's no doubt about it."
In an era where the women's grand slam titles have been shared around – there are currently 18 active singles champions – the chance for Barty to add her second title would cement her position as the best in the world.
Where others have found it difficult to stay at the top, Barty has motored serenely on, having reached at least the fourth round in eight of the last nine slams she's played, with the sole exception being her injury-enforced retirement in Paris.
"For Ash, the quality and consistency is there," Dokic explained.
"At times some of the girls have struggled for consistency after they've won a slam, they've struggled with the pressure and a lot of them have talked about that.
"I feel like after Ash won at Roland Garros she continued to play at such a high level and dealt so well with the pressure and expectation.
"That's not easy, Ash has so many great qualities in addition to her on-court attributes and that's why she's number one in the world."
Barty has dropped just a single set on her run to the final, and even that was hard fought, with the Australian conceding a tie-break to Carla Suárez Navarro in the opening round.
Coming off a month out of the game after injury forced her to abandon her Roland Garros campaign, it's an imposing record for the 25-year-old, one topped off by her straights sets semi-final win over Kerber.
"I feel like she's been getting better and better with each match, which is so impressive, especially since she hasn't played since the injury at Roland Garros," Dokic noted.
"It's also hard when you haven't had a good preparation, obviously she missed the grass court tournaments before Wimbledon because of her hip.
"Against Kerber it was almost the perfect match, and that's against an extremely tough opponent who knows how to play on grass, she's a former Wimbledon champion.
"To be able to win that in straight sets is so impressive."
Even on the rare occasions she's fallen behind, Barty hasn't panicked, displaying the level-headed composure for which she's renowned. When Kerber raced to a 3-0 lead in the second set of the semi-final, Barty simply dug deeper.
"Ash got on a couple of runs, one of them was 10 points in a row and another was 11 points in a row leading into the second set tie-breaker, against such a high quality opponent that's not easy," Dokic said.
"It just shows you that she's able to knuckle down and be extremely focused when it really matters.
"I've said it all tournament, she's played the big points extremely well, it's something that (Novak) Djokovic does well and Ash has been doing it here.
"I'm so excited to see her in the final, it would be so fantastic for her to win the tournament."
Barty has a 5-2 record against Pliskova, including wins in each of their last three matches, although the two most recent matches went to a third set.
Like Barty, Pliskova has only dropped one set this tournament, coming from behind to down Aryna Sabalenka in the semi finals, 5-7, 6-4, 6-4.
"They've been tough matches between Ash and Pliskova, the last one was 7-5 in the third set, but I feel like Pliskova is a better match-up for Ash than Sabalenka would have been," Dokic said.
"Sometimes Sabalenka can get on a run and it's really hard to counteract that because she's such a big hitter, even bigger than Pliskova.
"It will be tough tonight, but Ash is the favourite, even though Pliskova's semi final was one of the best matches I've seen her play, certainly at grand slam level.
"For Ash, I feel like she's got more belief and confidence, and she'll be able to expose so much of the Pliskova game with her slice, which she won't like, she'll have to hit up against that."
Barty has worn a tribute dress during this tournament to Evonne Goolagong Cawley, the last Australian to hold aloft the Venus Rosewater Dish, presented to the women's champion at Wimbledon since the 1880s.
But Dokic doesn't believe the pressure of breaking such a long drought will get to Barty.
"I think it will motivate her, it's never easy but she's talked about Evonne a lot, and just how instrumental she's been, even during her childhood," she said.
"We've seen the dress she's wearing that's inspired by Evonne, so hopefully that's an omen.
"It's a fantastic story, it's been 41 years but it would be phenomenal to see Ash lift the trophy."
