Former world number one Naomi Osaka says she does not "feel like I'm in my body" following her return to tennis after a maternity break.
Japan's Osaka returned to the WTA Tour in January after the birth of her first child, daughter Shai, in July 2023.
Since then, the four-time Grand Slam champion has struggled to rediscover her best form and been unable to advance past the quarter-finals at any tournament.
"My biggest issue currently isn't losses though, my biggest issue is that I don't feel like I'm in my body," Osaka, 26, wrote on Instagram on Tuesday.
