World number one Aryna Sabalenka survived a scare from veteran Laura Siegemund and came back from a break down twice in the deciding set to win in 2 hours and 54 minutes, the third-longest match of this year's Championships. Siegemund was bidding to win her first match against a world number one at her fifth try. The 37-year-old attempted to outlast Sabalenka from the baseline and won the first frame, 6-4. 

A runner-up at the Australian Open and Roland Garros already this season, Sabalenka was bidding to make her third Grand Slam final of the year and fourth in a row. The 27-year-old responded and took the second, 6-2. Siegemund, meanwhile, was aiming to become the oldest first-time Grand Slam semifinalist in the Open Era. The German kept Sabalenka off-balance again in the decider to break for a 2-1 lead. The Belarusian has reached the semifinals here the last two times she's played, in 2021 and 2023, but did not feature in 2022 or 2024. The top seed managed to fight back. 

Sabalenka claimed titles at WTA 1000 events in Miami and Madrid in addition to triumphing in Brisbane earlier this season. She closed out the contest 6-4 and advanced to her 12th career Grand Slam semifinal and also became the first player to qualify for this year's WTA Finals. Next up for her is Amanda Anisimova. 

"It's not like it's an unknown game, it's a smart game." said Sabelenka, "She's really making everyone work against her, and going into the match against her you know that you have to work for every point. It doesn't matter if you're a big server, if you're a big hitter, you have to work, you have to run, and you have to earn the win. Honestly I was just trying to focus on myself and make sure I don't give her that energy. I didn't want her to see that I was annoyed or anything by her, even if I was a little bit at some points. But I was trying not to give her that energy."
