Defending champion Ash Barty will face Elina Svitolina in the semi-finals of the Miami Open, with a win ensuring the Australian retains her world No.1 ranking.
Barty survived a huge quarter-final test in trying conditions with a hard-fought victory over the heavy-hitting Aryna Sabalenka.
The heat and humidity in South Florida reminds Barty of what conditions can be like in Queensland.
And she loves it, extending her winning run in Miami to 10, which includes her 2019 title success when the tournament was last played.
The world's top-ranked player didn't wilt against Sabalenka, winning the final nine points to prevail 6-4 6-7 (5-7) 6-3 for her third three-set win in four matches this tournament.
"I enjoy these courts," Barty said.
"You know, I enjoy the balls and how they are responsive to spin.
"A lot of different elements.
"But, you know, there are a lot of places around the world that I enjoy playing and here is one of them."
Barty and Sabalenka got a 10-minute heat break before starting the third set, though the Aussie looked like she didn't need much downtime after the resumption.
"Everywhere in the world there are different conditions and at times it suits you more than other places," Barty said.
"I feel like these are very familiar conditions for me.
"With the heat and humidity, it's very similar to Brisbane where I grew up and what I was born and bred and trained in my whole life."
Barty is now 18-3 in her past 21 three-setters, 10-1 in her past 11 quarter-finals and 12-3 in her past 15 meetings against fellow top-10 players.
She had gone more than 14 months without facing a top-10 player - mainly due to her staying home and away from the tour during the pandemic in 2020.
"You can't see me, but there's a massive smile behind my mask," Barty said in her on-court interview.
"It was certainly the best level I've played for a long time and especially over a sustained period."
A win over fifth-seeded Svitolina, who wasted little time defeating Anastasija Sevastova 6-3 6-2, will ensure Barty fends off the challenge of Naomi Osaka for the No.1 ranking.
Osaka can retake the top spot if she wins the WTA 1000 event in Miami and Barty fails to progress to the decider.
Since Osaka made history to become the first Japanese No.1 after winning the 2019 Australian Open, only she or Barty have held the top spot.
Barty first overtook Osaka to become No.1 for the first time on June 24, 2019.
