Naomi Osaka said she still does not feel like herself on court eight months into her comeback season following a maternity break, with the four-time Grand Slam champion puzzled at her lack of power and accuracy.

The 26-year-old was beaten by Ashlyn Krueger in the second round of qualifying for the Cincinnati Open, the latest setback in a patchy run of form heading into the final Grand Slam of the year at the U.S. Open, which runs from Aug. 26 to Sept. 8.

¡°My biggest issue currently isn¡¯t losses though, my biggest issue is that I don¡¯t feel like I¡¯m in my body,¡± Osaka wrote on Instagram on Tuesday.

¡°It¡¯s a strange feeling, missing balls I shouldn¡¯t miss, hitting balls softer than I remember I used to. I try to tell myself, ¡¯It¡¯s fine you¡¯re doing great. Just get through this one and keep pushing,¡¯ mentally it¡¯s really draining through.

¡°Internally, I hear myself screaming, ¡¯What the hell is happening?!?!¡¯¡±

Osaka returned to action in January after a 15-month break during which she gave birth to her daughter. Now ranked 90th in the world, her best results have been runs to the quarterfinals at Doha and ¡¯s-Hertogenbosch.

¡°I¡¯ve played a handful of matches this year that I felt like I was myself and I know this moment is probably just a small phase from all the new transitions (clay, grass, clay, hard), however the only feeling I could liken how I feel right now to is being post-partum,¡± Osaka said.

¡°That scares me because I¡¯ve been playing tennis since I was three, the racket should feel like an extension of my hand.¡±

Osaka¡¯s next event will be at Flushing Meadows, where she triumphed in 2018 and 2020, but she said she did not understand why everything about her game felt ¡°almost brand new¡± again.

¡°This should be as simple as breathing to me, but it¡¯s not,¡± she added.

¡°I genuinely did not give myself grace for that fact until just now.¡±

Despite her struggles, Osaka said she loved putting in the work each day and ¡°eventually having the opportunity to get to where you want to be.¡±
