Naomi Osaka perplexed by power struggles after Cincinnati setback

The Japanese player 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 from August 26 to September 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 quarter-finals 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".
