Elise Mertens eliminates Iga Swiatek at the China Open

Elise Mertens beat Iga Swiatek in the 2026 China Open quarterfinals and advanced to the semifinals in Beijing. Her qualification is confirmed by the official WTA tournament page, which describes the result as an upset and notes the continuation of the Belgian’s run. However, the material available from the consulted sources does not display the set-by-set score or identify her next opponent. Both details should be checked on the official WTA scores page, as the draw and schedule may change.

The confirmed result in Beijing

The victory came in the quarterfinals of the women’s tournament in Beijing. The WTA itself reports that Mertens eliminated Swiatek and reached her first WTA 1000 semifinal since 2021. The verified fact, therefore, is not merely that the Belgian won an important match: she became one of the final four players in an event of this category.

The exact score is not shown in the extracted text from the supplied official pages. Publishing it without a readable match record would mean adding an unsupported detail. Readers looking for games, sets or match duration should use the official scoreboard and select the China Open.

Why the victory carries sporting weight

The players’ backgrounds help put the result into perspective. According to Mertens’ WTA profile, her career-high singles ranking is No. 12, and she had collected ten tour-level singles titles. In 2026, she had been a finalist in Monterrey. Beijing also brought her first victory over Coco Gauff in six meetings, sending her into the quarterfinals before the win over Swiatek.

Swiatek, meanwhile, is a former world No. 1 with 26 singles titles in the record shown on her official profile. The Polish player won Toronto in 2026 and was the Beijing champion in 2023. Defeating a former champion of this tournament therefore gives Mertens’ run significance beyond advancement alone.

Mertens’ route through the tournament

The sequence available on the WTA pages shows two notable victories: first against Gauff in the round of 16, then against Swiatek in the quarterfinals. It is reasonable to view that combination as a high-impact run, but not as a guarantee of the title. The semifinal still has to be played, and no projection replaces the result on court.

The China Open is an outdoor hard-court WTA 1000 event. Its 2026 edition runs in Beijing from September 30 to October 11 and has a 96-player singles draw. Those features explain the importance of the semifinal berth without turning the elimination of a favorite into a premature conclusion about the rest of the event.

Who Mertens plays next

The sources reviewed do not clearly display the name of her next opponent. It is therefore not possible to state safely whom Mertens will face or provide a court or start time. The appropriate route is to check the updated draw on the tournament page and the schedule in the WTA scores section.

This caution also prevents a projected semifinal from being confused with an officially confirmed matchup. Once the pairing is published, the official draw will be the proper reference for the opponent, date and any scheduled time.

What to follow from here

Three points should be kept separate: Mertens’ place in the semifinal is confirmed; the detailed score is absent from the supplied material; and her next match depends on an official draw update. The WTA also offers regional broadcast information, but the sources for this article do not confirm a specific broadcaster for Brazil, France, the United States or Spain.

The central sporting conclusion is nevertheless clear: after already overcoming Gauff, Mertens eliminated a former world No. 1 and Beijing champion, returning to a WTA 1000 semifinal after five years. The full score and next fixture should be verified directly through the official channels.
