Naomi Osaka Reaches First Career Grass-Court Final After Battling Past Wang Xinyu at Bad Homburg Open

Naomi Osaka is one win away from a milestone that has eluded her for nearly two decades on tour: a grass-court title.

The four-time Grand Slam champion advanced to the final of the 2026 Bad Homburg Open on Friday with a straight-sets win over China's Wang Xinyu, marking the first time in her career she has reached a championship match on grass. The result also extends a career-best run on the surface just days before Wimbledon begins.

A career-first breakthrough

Osaka's path to elite tennis has always run through hard courts and, at times, clay, but grass had remained the one surface where she had never quite broken through. Entering the tournament as the No. 6 seed, Osaka had not previously reached a semifinal on grass since the 2018 Nottingham Open, and Friday's win secured the first grass-court final appearance of her career.

The breakthrough comes two years after Osaka returned to the tour following a layoff of more than a year, a stretch that included the birth of her daughter. Since coming back in 2024, she has worked to rediscover the form that once carried her to two Australian Open titles and two U.S. Open titles, four major championships in total. Friday's result is among the clearest signs yet that her game has rounded back into shape, even on a surface long considered her weakest.

Dominant from the start

Osaka set the tone for the semifinal in the opening set, overwhelming Wang behind a powerful and precise serve. She finished the first set with six aces and won 82 percent of her first-serve points, adding a strong 63 percent on her second serve to close it out comfortably.

The numbers behind Osaka's run through the tournament back up the eye test. Through her first three rounds at Bad Homburg, Osaka strung together six consecutive sets won without dropping one, while posting a first-serve point-win rate that ranked among the best in the field. In the quarterfinals, she dispatched Ekaterina Alexandrova in straight sets, 6-2, 6-2, conceding just two break points and winning 94 percent of her points on first serve.

Wang fights back, but too late

Wang, ranked outside the top 50 entering the tournament, had quietly built a strong run of her own to reach the final four. The Chinese player advanced to the semifinal without dropping a set across her first two matches, beating Renata Zarazua and Leylah Fernandez, before receiving a walkover into the semifinals when Elina Svitolina withdrew from the tournament with a right hip injury.

Against Osaka, Wang showed flashes of the form that had carried her through the draw. After falling behind a set, she broke Osaka's serve in the second set to level things at 2-all — the first real opening anyone had given her in the tournament against the Japanese star. It was a small crack in an otherwise dominant performance, but one that did not last. Osaka broke back immediately, and from that point the outcome was no longer in serious doubt. She closed out the second set 6-3 to seal her place in the final.

To her credit, Wang made Osaka work harder for the win than most of her previous opponents in Bad Homburg had managed, taking more points off Osaka's serve than the Japanese star had previously conceded in the tournament. But a single break proved to be the limit of what Wang could extract from the match.

Setting up the final

Osaka's opponent in Saturday's final will come from the day's second semifinal, pitting fourth seed Karolina Muchova against Romanian qualifier Elena-Gabriela Ruse for the second spot in the championship match.

Either finalist will arrive with credentials on grass. Muchova entered the tournament with a 27-8 record for the season and a 3-1 mark on grass, while in the eleven years prior she had compiled a 23-16 record specifically on grass courts. Muchova has reached the Wimbledon quarterfinals on two occasions, giving her a track record on the surface that Osaka has largely lacked until this week.

Timing that could not be better

The breakthrough arrives at a particularly useful moment on the calendar. Wimbledon begins Monday, June 29, and a deep run — let alone a title — in Bad Homburg would be the clearest signal yet that Osaka's serve-driven game has finally translated to grass heading into the year's third major.

Her statistical profile through the week supports the idea that this is not simply a hot run, but a more complete version of her game finding its footing on a surface that had resisted her for years. Through her run to the final, Osaka won 79 percent of points behind her first serve and 59 percent on her second, while converting more than half of her break-point opportunities against elite-level competition.

For a player who has spent the better part of two years working her way back from an extended absence and toward the level that once made her one of the most feared servers and ball-strikers in the women's game, Saturday's final represents both a milestone and a test. A title in Bad Homburg would not just be Osaka's first trophy on grass — it would also hand her significant momentum heading straight into the All England Club, where the surface that has long given her trouble will once again take center stage.
