Karolina Muchova claimed the Bad Homburg Open title after Naomi Osaka retired from the final due to injury, giving the Czech player her first WTA grass-court championship in her debut at the tournament.

Muchova had no previous WTA title on grass before this week. The win fills that gap in her résumé and comes on her first appearance at Bad Homburg, adding weight to the achievement within her career.

How the final ended

Osaka stopped play before the match was completed and did not return to court. With sets still in progress at the time of withdrawal, tournament organizers declared Muchova champion by retirement. Osaka was recognized as runner-up despite not finishing the match — a result that reflects a competitive week for the Japanese player before the final.

Next: Wimbledon

Muchova heads to Wimbledon carrying a grass-court title and match rhythm on the tour’s most technically demanding surface. Osaka’s participation in the Grand Slam, given her injury, remains to be confirmed.
