LONDON (AP) — Sure, Naomi Osaka is a four-time Grand Slam champion who also impresses with her fashionable outfits.On Tuesday, she sounded like the rest of us. The plantar fasciitis was acting up. She’s working too much.“I’m just getting old,” Osaka said.The 28-year-old Osaka’s Wimbledon run and fashion show ended in a 7-6 (4), 6-4 loss to Karolina Muchova in the quarterfinals of the grass-court Grand Slam.Osaka, a former No. 1 player, had ousted top-ranked Aryna Sabalenka in the fourth round — with arguably some of her best tennis since returning from maternity leave — but couldn’t find her rhythm Tuesday against her Czech opponent.“It’s hard because I played so well in my last match, then today I just feel like I didn’t play well at all and I didn’t have any energy,” said Osaka, who despite the loss still had her best result at the All England Club by reaching the quarterfinals.

“I could feel it coming because I’ve played way more matches than I usually do before a Slam,” she added. “I just wanted to try that to see the rhythm, you know? Obviously it worked out well. But I think I probably won’t do that again. But yeah, I would say it was like an accumulation of playing two weeks straight without a day off.”
