Naomi Osaka's best-ever Wimbledon run ended Tuesday with a7-6 (4), 6-4 quarterfinal defeat to Karolina Muchova, and the four-time Grand Slam champion didn't hide her frustration afterward. Having upset top-ranked Aryna Sabalenka just a round earlier, Osaka struggled to find her footing against the Czech player, admitting she felt drained of energy despite the strong form she'd shown days before.
When she was asked if an ankle issue was behind her flat performance, Osaka laughed off the idea and joked about simply "getting old" at 28. She then got more specific, saying she believes she's dealing with plantar fasciitis, a condition she said first flared up in the off-season last year and resurfaced once she hit the grass courts of the All England Club. She had already been forced to retire from a Wimbledon tune-up final in Bad Homburg, Germany, earlier this season because of the same foot issue.
Plantar Fasciitis: The Culprit Behind a Loss?
Osaka described the injury in her own words rather than through a formal diagnosis, telling reporters she has "plantar fasciitis on my feet. Well, that's what we assume it is." She theorized that playing more explosively off her toes lately, combined with the different demands of grass compared to hard court, may have reactivated the issue.
"I think it reactivated on grass court because I'm pushing off a lot more to go forward," she said, adding that she didn't expect it to be a problem once the tour moves back to hard courts. She also pointed to a packed schedule as a contributing factor, noting she'd played considerably more matches heading into this Grand Slam than she typically would.
That combination of a heavy match load on an unfamiliar surface, paired with a foot issue she'd already battled once this season, lines up with how plantar fasciitis commonly develops: through repeated stress on the tissue connecting the heel to the toes, especially during fast lateral sports, which is what grass-court tennis demands.
A Closer Look at Plantar Fasciitis
According to MayoClinic, Plantar fasciitis is inflammation of the plantar fascia, the thick band of tissue running along the bottom of the foot that connects the heel bone to the toes and supports the arch. It's the most common cause of heel pain, affecting roughly 1 in 10 people at some point in their lives.

Common symptoms:
Causes
: Overuse or excessive stress on the plantar fascia, often from being on your feet for long stretches, playing sports, exercising on hard surfaces, skipping warmups, or wearing unsupportive footwear
- Stabbing or aching pain in the heel or arch, often worst with the first steps after waking up or standing after sitting
- Stiffness in the foot
- Swelling around the heel
- A tight Achilles tendon
- Pain that eases during activity but returns afterward
- Risk factors : Flat feet or high arches, certain repetitive-impact activities like running or dance, excess body weight, and occupations that require standing for long periods
- How it's diagnosed : Typically confirmed through a physical exam, where a provider reviews symptoms and gently presses on the plantar fascia to check for tenderness; imaging like X-rays, ultrasound, or an MRI is only used if another condition is suspected
- What to do : Rest, ice the area for 10–15 minutes at a time, wear supportive shoes, and try gentle stretching; over-the-counter anti-inflammatory medication can help with pain in the short term
- When to see a provider : If heel or foot pain doesn't improve within a week, or persists beyond two weeks of home treatment, since ignoring it can lead to a change in gait that causes knee, hip, or back problems down the line
Age Isn't Just a Number, It's an Indicator
Osaka's offhand remark about "getting old" points to something bigger than one uncomfortable press conference: even elite athletes with access to top medical care often deal with common, everyday conditions like plantar fasciitis, and openly discussing them helps normalize a condition that affects everyday people far more often than headline-grabbing injuries do.
Her situation is also a useful example of how minor, chronic issues can shape performance under the brightest lights. Osaka didn't attribute her loss to a single dramatic injury, but to a nagging condition compounded by heavy match play, exactly the kind of accumulated wear that recreational athletes and weekend runners experience too, just without cameras watching.
For anyone brushing off similar heel pain as no big deal, her comments are a reminder that plantar fasciitis, while rarely serious, is worth addressing early rather than playing through indefinitely.
