Dominance on the court in Riyadh: The course of the match against Kasatkina

September 10, 2026, will go down in history as the moment Iga Świątek definitively silenced speculation regarding her form in Riyadh. The victory over Daria Kasatkina in the final group stage match of the WTA Finals left no room for doubt. The Pole wins and advances to the semifinals. It is a direct qualification, earned in the manner her fans have become accustomed to during the best moments of her career.

Almost everything worked in this match. Above all, the serve, which had been temperamental in recent weeks, was precise and difficult to read this time. Świątek not only protected her own service games but, most importantly, dictated terms on the Russian's serves from the very beginning. An aggressive return became the main tool that allowed the leader to control the rallies. Kasatkina, a player well-known for her defensive patience, was unable to find any answer to such intensity. Every shot from the Pole had a specific purpose.

After a difficult period in North America, where painful defeats at the US Open followed her success in Toronto, this performance in Saudi Arabia is the strongest response to the skeptics. The competition in Riyadh proved that the coaching staff has learned from recent setbacks. Stabilizing her form at such an important moment in the season is a clear warning signal to the other players in the field. A semifinal pass is now a fact, and the style in which Świątek earned it restores faith in the dominance we remember from the Canadian courts. Now, the real fight for the trophy begins, where the margin for error is reduced to zero. Every subsequent match will require the same concentration we saw on the court today.

Balance after the US Open: How did Świątek react to the defeat?

The victory over Daria Kasatkina in the final group stage match of the WTA Finals in Riyadh definitively closes a chapter that caused serious concern in the Pole's camp just two months ago. Advancing to the semifinals is not just a sporting success; it is primarily proof of stabilized form, which was far from ideal in New York. Let us recall: as recently as September 7, 2026, the mood was quite different. The defeat in the US Open round of 16 to Qinwen Zheng became a symbol of that crisis, after which the WTA ranking looked significantly worse for the Polish player.

That match in New York was a textbook example of the mental and technical instability that plagued Świątek during the American summer. Experts were merciless in their diagnoses. Dawid Celt, analyzing the causes of that defeat, pointed to a fundamental problem with concentration and managing leads: "That is why Iga Świątek was winning 5:0 and lost 5:7." This brutal assessment best reflects the state the leader of Polish tennis was in at the time. A lack of stability in key moments caused certain victories to slip through her fingers, which affected the perception of her form before the end of the season.

Riyadh shows a different tennis player. While it seemed in August, after winning the tournament in Toronto, that Iga was returning to a winning path, the New York setback put a big question mark over her preparation for the world finals. Today's advancement to the top four players of the season is the best possible answer to that criticism. Świątek has stopped squandering leads, which proved decisive against Kasatkina. The WTA Finals semifinal is hard proof that the lesson from the US Open has been learned.

Situation in the WTA ranking: The fight for points after September 10, 2026

The victory over Daria Kasatkina in the final group stage match is a ticket to the WTA Finals semifinals in Riyadh for Iga Świątek. The Pole could not afford a slip-up, and the scenario where she ends her season prematurely seemed like a very real threat until recently. The tournament in Saudi Arabia has grown into a rescue mission for this year's ranking. After a series of failures in North America, every win in Riyadh now weighs twice as much.

The situation in the table is tense. As recently as September 7, headlines circulated about painful drops after the US Open, where Świątek was eliminated earlier than expected. The defeat to Qinwen Zheng in the US Open round of 16 (07.09.2026) forced the player's staff to change priorities. Points lost in New York had to be recovered at an express pace, and Riyadh became the only place where the end of the season could still be saved.

Here is the balance of the last few weeks that influenced the Pole's position:

Result of the match against Qinwen Zheng (US Open) — defeat (Przegląd Sportowy, 07.09.2026)
Result of the match against Marie Bouzkova (3rd round of US Open) — win (Przegląd Sportowy, 05.09.2026)
Result of the WTA tournament in Toronto — victory (Polsat Sport, 14.08.2026)
Ranking status after US Open — bad news (Przegląd Sportowy, 07.09.2026)

Success in Toronto in mid-August gave hope for stability, but the US Open showed how fragile Świątek's advantage is. The lack of points from New York meant that the top of the ranking closed in dangerously. The competition in Riyadh is not just a fight for a trophy, but above all an attempt to maintain distance from chasing rivals. Getting out of the group is not a success in itself; it is merely a necessary condition to keep in touch with the leaders. Now that the semifinal is a fact, the pressure shifts to the later stages, but the margin for error remains zero.

Tactical adjustments: What has changed since Toronto?

The victory over Daria Kasatkina in the final group stage match in Riyadh ends a period of searching and definitively secures Iga Świątek a direct advancement to the WTA Finals semifinals. This is confirmation that the Pole's staff managed to develop solutions that were so desperately missing during the August struggles on hard courts. Analyzing the last few weeks, a clear correction in the way energy and rally tempo are managed is visible.

However, the stabilization of form did not come overnight. After winning the WTA tournament in Toronto, which ended on August 14, 2026, a quick collision with reality followed. The defeat to Elena Rybakina, recorded on August 21, 2026, exposed old demons: an overly defensive attitude in key moments and a lack of patience when finishing rallies. Rybakina showed then that aggressive tennis still poses a barrier that is difficult for Świątek to overcome when the Pole gives up the initiative.

The staff drew conclusions. Changes are visible in the following aspects:

Abandoning the attempt to overpower rivals in every rally in favor of keeping the ball deep in the court, which we saw in the clash with Kasatkina.
Increased tactical discipline on her own serve, eliminating the lulls that Dawid Celt mentioned after the US Open when analyzing form fluctuations while leading 5:0.
Better reading of opponents' games at the end of sets, which allowed avoiding scenarios like 5:7, which were the bane of Świątek during the American tour.

Will these corrections be enough for the semifinal? The world number one remains the tournament favorite, but Świątek in Riyadh resembles the version from Toronto more than the one that lost in the US Open round of 16 to Qinwen Zheng. This is not a return to the dominance of previous seasons, but a pragmatic management of her own potential. Success in Riyadh shows that the current Świątek is capable of winning even when things are not going her way.

Road to the final: Who is waiting in the semifinals?

The win against Daria Kasatkina in the final group stage match of the WTA Finals in Riyadh ends the period of uncertainty and officially opens the door to the semifinals for the Pole. This result means direct advancement from the group, which just a few days ago, after the painful defeat to Qinwen Zheng at the US Open, seemed like an almost unrealistic scenario. Świątek, despite clearly weaker form at the beginning of September, managed to regain the rhythm that accompanied her during her August triumph in Toronto.

Now attention shifts to the tournament bracket. The conclusion of the group stage will determine the final balance of power, and Świątek's opponents in the fight for the final will be the top-ranked players who dominated the parallel group. Although we will only know the exact composition of the semifinals after the final matches are played, fans must prepare for clashes with tennis players who have presented much more stable form in recent weeks than the Pole did during the New York tournament.

One must look at this competition through the prism of the problems that Dawid Celt spoke about openly. The defeat at the US Open, where Świątek gave up a 5:0 lead, losing the set 5:7, is still a fresh signal that concentration remains a fragile element of her tennis. Even after the victory over Kasatkina, the road to the final in Riyadh will not be a walk in the park. Potential opponents have already seen the Pole lose leads and will certainly exploit every moment of hesitation. If Świątek wants to think about the final triumph, she must eliminate the errors that cost her a drop in the WTA ranking after losing to Zheng. The semifinal in Riyadh is a test not only of technique but, above all, of resistance to pressure, which will not be lacking in Riyadh. This is not the same tournament as in Toronto, and the stakes are higher than just the result of one match.

Financial and prestigious dimension of the WTA Finals

The victory over Daria Kasatkina in the final group stage match secures Iga Świątek a direct advancement to the semifinals of the WTA Finals in Riyadh. For the Pole, this is not just a return to playing for the highest trophies, but above all a confidence boost after a series of difficult months. After the August win in Toronto and the subsequent farewell to the US Open at the round of 16 stage, there is more at stake in Saudi Arabia than just ranking points.

The WTA Finals is the culmination of the calendar in the 2026 season. The tournament in Riyadh, due to its rank and prize pool, is the ultimate test of form for the world's top tennis players. Świątek, fighting to maintain her position in the strict hierarchy after shaky form in New York and matches against rivals such as Qinwen Zheng or Elena Rybakina, perfectly understands the weight of this moment. A lack of success in this tournament could deepen the pessimistic moods that accompanied fans after recent reports of drops in the WTA ranking.

Being in the semifinal changes the perspective. It is a guarantee that the end of 2026 will not be merely a desperate defense of the achievements from previous months. Świątek needs this success to close the season with a sense of control, and not in the shadow of lost tie-breaks or expert criticism, such as that flowing from Dawid Celt's analyses regarding problems with maintaining set leads. Riyadh has become an arena where the Pole must prove that her tennis foundation is still strong enough to dominate the women's tour. Every subsequent win is not just money and points; it is primarily a signal sent to rivals before the next year of competition.
