The two matches promise contrasting storylines at the WTA 1000 tournament. Swiatek is aiming to keep her season-ending qualification hopes alive, while Kartal is enjoying a remarkable comeback after six months away from competition.
Ostapenko, meanwhile, is seeking her first final appearance of the season at a WTA 1000 event, and Chwalinska has the opportunity to continue her breakthrough campaign on one of the biggest stages in women's tennis.
Swiatek faces Chwalinska in all-Polish semi-final
Swiatek booked her place in the last four with a commanding 6-4, 6-1 victory over American Ann Li in the quarter-finals. The Polish star has progressed through the tournament without dropping a set, also defeating Magdalena Frech and Ashlyn Krueger in earlier rounds.
Despite her pedigree as a six-time Grand Slam champion, Swiatek has endured a comparatively challenging 2026 season by her standards. Her title in Toronto remains her biggest achievement of the year, and reaching the Wuhan final is crucial to keeping her bid for a place at the WTA Finals alive.
Standing in her way is Chwalinska, who continued her impressive run by defeating Greece's Maria Sakkari 6-0, 3-6, 7-5.
Chwalinska has already enjoyed a breakthrough year, reaching the French Open final before building momentum again during the Asian swing. Her progress in Wuhan has demonstrated her ability to compete against established players, and she will now face one of the sport's most accomplished competitors.
A rivalry with a long history
Although this will be their first meeting on the WTA Tour, Swiatek and Chwalinska have history dating back to their teenage years. Swiatek won their only previous professional singles meeting at an ITF tournament in Stockholm in 2016.
Swiatek will enter as the favourite because of her experience and consistency at WTA 1000 events. Chwalinska, however, has little to lose and will be eager to turn her outstanding tournament into a place in the final.
Kartal's remarkable comeback continues
The other semi-final features Britain's Kartal against Latvia's Ostapenko, with both players arriving after impressive quarter-final victories.
Kartal defeated world No. 6 Elina Svitolina 6-2, 2-6, 6-4 to reach the first WTA 1000 semi-final of her career.
The result continued an outstanding run for the British player, who has beaten three seeded opponents in succession after overcoming Belinda Bencic and Jasmine Paolini in earlier rounds.
Kartal's achievement is particularly notable because she is competing in only her second tournament since a six-month absence. Her performance in Wuhan has offered a reminder of her ability to challenge leading players when fit and confident.
The British star will now seek to take another major step forward by reaching the biggest final of her career.
Ostapenko returns to Wuhan semi-finals
Ostapenko booked her place in the semi-finals with a 7-6(6), 6-1 victory over 11th seed Diana Shnaider.
The Latvian showed considerable resilience in the opening set, recovering from 2-5 down and saving multiple set points before taking the tie-break. She then dominated the second set to complete the win.
Ostapenko's path to the last four has included three-set victories over Jessica Pegula and Leylah Fernandez, highlighting her ability to fight through demanding matches.
The former French Open champion is also returning to the Wuhan semi-finals for the first time since 2017. She has not reached a final since winning the Stuttgart title in April 2025, making this tournament an important opportunity to revive her season.
Kartal and Ostapenko renew their rivalry
The head-to-head record between Kartal and Ostapenko stands at 1-1, with both previous meetings taking place on grass in 2025.
Ostapenko won their encounter in Eastbourne, while Kartal prevailed at Wimbledon. Their Wuhan meeting on hard courts therefore presents a fresh challenge for both players.
Kartal will hope her confidence and recent run of victories can carry her through, while Ostapenko will look to impose her aggressive baseline game and powerful shot-making.
The Latvian has struck more winners than any other player in the tournament, according to Flashscore's preview, making her a dangerous opponent despite Kartal's impressive momentum.
