Quarterfinal action at the WTA Adelaide International will feature multiple top 10 players taking the court on what promises to be a good day of tennis in South Australia. As  ever, LWOT will offer predictions for all four matches as well as the quarterfinal action at the WTA Hobart International. But who will reach the semifinals?

WTA Adelaide Quarterfinal Predictions

Yulia Putintseva vs Diana Shnaider

Head-to-head: Putintseva 1-0 Shnaider

This pair have only met once in their careers, in 2023, just as Diana Shnaider was beginning her rise towards the top of the game. Yulia Putintseva has played great tennis this week, defeating Donna Vekic and Ons Jabeur with relative ease. On the other hand, Shnaider had a disappointing tournament in Brisbane last week, and she hasn’t looked convincing this week yet, trailing former Wimbledon champion Marketa Vondrousova before an injury forced the Czech to retire. The Russian’s lefty game can heat up at any given point, but Putintseva looks more convincing in this matchup.

Madison Keys vs Daria Kasatkina

Head-to-head: Keys 9-2 Kasatkina

A twelfth meeting is on the cards in this quarterfinal matchup, with Madison Keys has proved over time that she has the edge against Daria Kasatkina. They’ve played each another in big matches, such as in the final of a WTA 500 event in Eastbourne, with Keys winning nine of their elevent matches. That said, it is worth noting that the world #9’s only win over Keys on hard courts did occur in Australia, in 2022.

Keys’ powerful game usually matches up well against counterpunchers, as is the case with this matchup. While Kasatkina has looked sharp this week, Keys has had to defeat far tougher competition — taking out the defending champion Jelena Ostapenko to make it to the quarterfinals, though the American’s two matches in Adelaide so far have been against power-hitters so the change in pace might be difficult for her. Still, she should have enough to reach the semifinals.

Prediction: Keys in 3

Liudmila Samsonova vs Emma Navarro 

Head-to-head: first meeting

This should be an entertaining first-time matchup on the WTA Tour. When at the top of her game, Liudmila Samsonova is one of the toughest players to face off against. Her inconsistent patches have prevented a big run at a tournament or Top 10 debut. Her two wins had to go to a third set, and she’s hit a bit too many double faults this week. Meanwhile, Navarro, surely eyeing another deep run at a Major in Melbourne, has rebounded after a disappointing tournament in Brisbane last week, taking out Ekaterina Alexandrova in her opener at the WTA Adelaide International. The American’s topspin, angles and skills on the court should counter Samsonova’s fast and powerful groundstrokes. Look for Navarro to win in two close sets.

Jessica Pegula vs Ashlyn Krueger

Head-to-head: Pegula 3-0 Krueger

After withdrawing from Brisbane with an injury, Jessica Pegula’s first match in Adelaide couldn’t have gone better. She cruised past her rival Maria Sakkari 6-4 6-1. Ashlyn Krueger, meanwhile, clearly has a bright future and has already put together a solid 6-2 record in 2025. Krueger could come away with the upset if she attacks Pegula’s serve, but the amount of matches she’s played this week suggests some caution about her chances would be wise. The 20-year-old is a lucky loser in this event, and three of her four matches this week have gone to a third set. Pegula will be fresher and should win this match as a result.
