The final four French Open quarterfinal spots will be locked up on Day 9 as we start to make our way toward the business end of the tournament. Two of the biggest names in tennis, Aryna Sabalenka and Naomi Osaka, square off in what is a blockbuster. As always, our writers offer their rountable predictions. But who will advance?
French Open Day 9 Predictions
Anna Kalinskaya vs Anastasia Potapova
Tope
Anna Kalinskaya leads the head-to-head 2-0, but both of those wins came on hardcourt, and the last time these two shared a court was four years ago. Clay is a completely different beast, and right now Potapova owns it. She’s been the form player of the clay swing, and toppling the reigning Roland-Garros champion Coco Gauff, isn’t just a result, it’s a statement of intent. Kalinskaya did her job against Camilia Osorio but was far from convincing in a match that raised more questions than answers. Potapova walks into this fourth round riding a wave of belief, momentum, and red clay in her bones — and on this surface, at this moment, the head-to-head means very little.
Prediction: Potapova in 3
Jordan
Potapova’s run of form has been unexpected. She possesses a very good chance against Kalinskaya, whose game is more naturally suited to hard courts. I think Potapova will build on her outstanding triumph against Coco Gauff here.
Prediction: Potapova in 3
Ateet
Anastasia Potapova upset the defending champion Coco Gauff in a three-set thriller. She went toe-to-toe with Gauff from the baseline but also had the power to finish the rallies with winners. She is playing the best tennis of her life and is my favourite to reach the quarterfinal. Anna Kalinskaya is a dangerous player and has the head-to-head advantage, but their last meeting was in 2022. Potapova is a much better player now and in terrific form.
Prediction: Potapova in 3
Ilemona
Anastasia Potapova stunned defending champion Gauff in one of the biggest upsets of the tournament. That is a significant confidence boost, but she arrives having spent more time on court than Anna Kalinskaya. Kalinskaya’s aggressive baseline game is the right style to exploit Potapova’s tendency to go flat in key moments, and her seeding and ranking reflect a genuine quality edge. Kalinskaya should come through a competitive match.
Prediction: Kalinskaya in 3
Zain
Anastasia Potapova had one of the upsets of the first week when, in arguably her best match performance ever, she took out the defending champion Coco Gauff. Now against Anna Kalinskaya, this is a matchup in which she will face a player willing to attack from the baseline, much like herself.
Both of these players have played against each other in doubles and singles, and have also teamed up together in doubles, meaning they know each other’s games pretty well. Serve will be crucial, as the second serves in this match is expected to be punished by the returner. I think Kalinskaya might have the edge from the serving department, but Potapova is the better mover on clay. She is also coming into this match with the confidence of one of her best wins ever. And while that might cause a natural letdown, I expect Potapova to keep that level up for at least one more match and make the last eight in Paris this year.
Prediction: Potapova in 3
Diane Parry vs Maja Chwalinska
Tope
Maja Chwalinska is on warrior’s high and her resilience alone makes her the favourite, but But Parry is no passenger in this story. The Frenchwoman just dismantled sixth seed Anisimova on Philippe-Chatrier in front of a crowd that was less spectator, more weapon and that same crowd will show up again, louder and hungrier, for a quarterfinal place.
Prediction: Parry in 3
Jordan
This is a fascinating battle between two players who most did not expect to reach this stage. Parry will have home advantage, and the benefit of a more unconventional game compared to most WTA players. However, Chwalinska just seems totally locked in right now, and I think she can effectively target Parry’s weaker backhand.
Prediction: Chwalinska in 2
Ateet
This is the most surprising fourth-round matchup, but both players thoroughly deserve to be here. Diane Parry used her backhand slice to great effect against Amanda Anisimova, but that might not be as effective against Chwalinska. However, the crowd will once again be a factor which could disrupt Chwalinska and benefit the Frenchwoman.
Prediction: Parry in 3
Ilemona
Maja Chwalinska beat Sakkari in three sets after dropping the first set, demonstrating the mental resilience to recover when things go wrong. Diane Parry beat Anisimova in a tense three-setter, with the home crowd driving her over the line. Both players have been among the stories of the tournament, but this is Parry’s home Slam and the Roland Garros crowd is her most powerful weapon. The crowd factor in a match this close could prove decisive.
Prediction: Parry in 3
Zain
When the draw was made over a week ago, not many would have thought that we would get a Diane Parry vs Maja Chwalinska matchup in the second week, but here we are. Both of these players have made the most of the opportunities they were given, had impressive wins along the way, and now feel they have a real shot at making the quarterfinals.
Chwalinska will look to use her court craft and lefty angles to disrupt her opponent’s rhythm once again, which can prove effective against Parry. Meanwhile, with a packed crowd behind her, Parry will look to use her slice and all-court game to get Chwalinska into tricky positions. Ultimately, in a match where nerves are expected, I expect the player with a whole stadium behind her to have the edge needed to come out on top in what should be a three-set battle.
Prediction: Parry in 3
Madison Keys vs Diana Shnaider
Tope
Madison Keys and Diana Shnaider are set to collide in what promises to be a bazooka shootout, two big hitters who’ll trade flat, heavy groundstrokes until someone blinks first. Keys survived the gutsy Victoria Mboko, while Shnaider, in contrast, was ruthless in dispatching Oleksandra Oliynykova and arrives full of confidence but that 0-3 head-to-head shadow looms large, and Keys has a knack for finding another gear when it matters most and if she brings her A-game, the fourth meeting looks likely to end the same way as the first three.
Prediction: Keys in 2
Jordan
Keys is a realistic title contender, especially with how the draw has opened up. The American is also among the most capable of beating Sabalenka or Osaka to reach the final. Shnaider’s game, while impressive, does not carry the same threat, and her opponent’s confidence from beating Victoria Mboko will probably prove crucial.
Prediction: Keys in 2
Ateet
Madison Keys has quietly reached the fourth round when not many people expected her to. Now that she is here, her tennis is good enough to trouble anyone. The most important thing is that she looks healthy and confident. Diana Shnaider has yet to lose a set, and she has troubled Keys in their last two meetings. Paris’s temperature has returned to normal, which should slow down the conditions and benefit Shnaider.
Prediction: Shnaider in 3
Ilemona
Diana Shnaider was dominant in beating Oliynykova 7-5, 6-1 and arrives with momentum and minimal fatigue. Madison Keys has been solid but measured through the draw, and her flat power game is a genuine weapon. Shnaider’s own power and current confidence, however, make this one of the more competitive fourth-round matches. This should be close, but Keys’ experience in big matches and cleaner path could help her edge it out.
Prediction: Keys in 3
Zain
Both these players are known for their aggressive baseline play, a playstyle that does not necessarily suit slower clay, but given how cleanly they hit the ball, they make it work.
While Madison Keys is the slightly better overall ball striker and has the experience edge, Diana Shnaider’s lefty angles and point construction can cause trouble on clay. But in this matchup, it has largely come down to which player can seize the momentum from the back of the court, which the American has managed to do more or less in every encounter so far. And while I expect this to be a close match, Keys’ confidence in this matchup makes me give her the slight edge.
Prediction: Keys in 3
Aryna Sabalenka vs Naomi Osaka
Tope
The one thread Naomi Osaka can cling to in this one is the heat. If Paris bakes, the slower, higher-bouncing conditions could neutralise some of Sabalenka’s power and give Osaka’s flatter ball-striking a fighting chance as Roland Garros is new territory for her; clay has never been her cathedral the way it has been Sabalenka’s hunting ground. Expect Sabalenka to win, but don’t expect a straight-sets stroll.
Prediction: Sabalenka in 3
Jordan
Sabalenka last failed to reach the Grand Slam quarterfinals (only counting Majors that she participated in) at the 2022 French Open. That underlines the challenge that faces Osaka. The Japanese star’s best tennis is capable of competing against the world No. 1, but Sabalenka’s ruthlessness makes her the more likely winner.
Prediction: Sabalenka in 2
Ateet
World No.1 Aryna Sabalenka defeated Daria Kasatkina in straight sets, but her level wasn’t that great in the second set. She will meet Naomi Osaka for the third time this season and must be ready for a tough battle. Naomi Osaka played one of her best matches on clay to defeat Iva Jovic in a fantastic match. I think this is going to be one of Sabalenka’s biggest tests this season, and she will need to be at her best to win this.
Prediction: Sabalenka in 3
Ilemona
Aryna Sabalenka dispatched Kasatkina in straight sets while Naomi Osaka needed nearly three hours to get past Jovic. The physical disparity between the two is significant heading in. Osaka said their Madrid match earlier this year was tight and has shown her best clay form in Paris, but Sabalenka’s combination of power, freshness and current dominance on this surface make her extremely difficult to overcome.
Prediction: Sabalenka in 2
Zain
The standout match of the day features two four-time Major champions as Naomi Osaka takes on World No. 1 Aryna Sabalenka. In her deepest run at the French Open yet, Osaka has served exceptionally well this week, but it has been her aggressive baseline game that has got her to this point. Against Sabalenka, she will once again need it at its best, as Sabalenka is the best aggressive baseliner in the world currently and will look to overpower Osaka from the baseline.
Both players will need to serve well, but ultimately, this match comes down to which player can gain the baseline advantage. And while Osaka has shown this tournament that she can have decent results on slower clay, Sabalenka’s edge in movement, defensive scrambling, and variety from the back of the court are advantages enough for me to go with the World No.1 here.
