Osaka reaches first Washington quarterfinal as Krueger retires with right ankle injury

Naomi Osaka secured her spot in the quarterfinals of the Mubadala Citi DC Open on Wednesday night. She defeated Ashlyn Krueger after the latter retired due to a right ankle injury. At the time of the retirement, Osaka led 6-3, 3-1.

Krueger struggled with the injury throughout the match, requiring a medical timeout during the first set. She managed to play on for a short period in the second set before ultimately stopping the match after 53 minutes. This marks her first mid-match retirement since early 2025.

For Osaka, the victory marks her third consecutive quarterfinal appearance. She enters this match following deep runs at both the Bad Homburg tournament and Wimbledon. Her performance on Wednesday showed significant promise as she transitioned back to hard courts, an environment where she has historically excelled.

Statistically, Osaka performed well under pressure. She did not face a single break point throughout the evening and won 80 percent of points on her first serve. Her offensive efficiency remained high, with an 11-5 winner-to-unforced-error ratio. She now prepares to face Elisabetta Cocciaretto, who earned her own spot in the next round by defeating Emma Navarro.

Osaka and Cocciaretto have faced each other once before, during the 2024 Miami tournament, where Osaka won in straight sets. The winner of their upcoming Friday match will move on to the semifinals in Washington, where they will compete against either Elina Svitolina or Alexandra Eala.
