MIAMI — The heat and humidity this time of year in South Florida remind Ash Barty of what conditions can be like in her native Australia. She loves it.
The world’s top-ranked player didn’t wilt in the conditions Tuesday at the Miami Open, winning the final nine points to finish off No. 7 seed Aryna Sabalenka of Belarus 6-4, 6-7 (5), 6-3 in a quarterfinal matchup — her third three-set win in four matches in this tournament.
“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.”
Temperatures reached the mid-80s on Tuesday, and the humidity made it feel even hotter, especially without any shade on the court. Barty and Sabalenka got a 10-minute heat break before starting the third set, though the defending Miami champion from when the event was last held two years ago looked like she didn’t need much downtime.
Barty faced seven break points in the match and saved them all. She will meet No. 5 seed Elina Svitolina in Thursday’s semifinals; Svitolina eased past Anastasija Sevastova 6-3, 6-2 on Tuesday night to make the final four in Miami for the first time.
Barty is now 18-3 in her past 21 three-setters, 10-1 in her past 11 quarterfinal matches and 12-3 in her past 15 meetings against fellow top-10 players. And she ran her winning streak in Miami to 10 matches.
“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.”
