Naomi Osaka retired from the Bad Homburg Open final after a foot injury forced her out early in the second set. The fourth seed was down 6‑1, 1‑0 to Czech Karolina Muchova when she called time, shook hands and left. A win would have given Osaka her first grass title, completing a comeback after a year‑long tour hiatus.

The injury surfaced following a medical timeout in the opening set, suggesting the problem worsened as Osaka tried to rally. A four‑time Grand Slam champion, she has never progressed beyond Wimbledon’s third round, making the timing of the setback particularly damaging. Her first‑round opponent, France’s Elsa Jacquemot, now faces a rested opponent. Medical staff confirmed swelling on her right foot, limiting her mobility.

Osaka thanked the crowd during the brief trophy ceremony, apologising for not finishing the match but praising the week’s atmosphere. With Wimbledon opening Monday, she must manage the foot issue quickly to avoid a repeat of past early exits. Should the injury persist, Osaka could face a withdrawal, forcing a lucky loser into the draw.
