What happened in Cincinnati
Cincinnati Open 2026, quarterfinals against Iga Świątek. Rybakina injured her left ankle during the match and could not continue; the retirement was recorded officially. It was her second withdrawal of the season - in February in Dubai she had retired in the third round with illness.
The timing could hardly have been worse: the US Open was less than a week away and she was in the middle of the race for the No. 1 ranking.
Did Rybakina play the US Open?
Yes. Despite speculation about a withdrawal she confirmed her entry and opened against Thea Frodin. No visible movement restrictions appeared over the fortnight: she beat Jessica Bouzas Maneiro, Yuliia Starodubtseva, Naomi Osaka and Zheng Qinwen, playing two three-set matches along the way.
What that tells us. The problem was not structural but the kind that responds to taping and load management. Five matches in ten days in New York heat, two of them going the distance, is reasonable evidence that the ankle holds up.
Injuries and withdrawals
| When | Tournament | Cause | Outcome |
|---|---|---|---|
| August 2026 | Cincinnati Open, quarterfinals | Left ankle injury | Retired mid-match |
| February 2026 | Dubai Championships, third round | Illness | Retired mid-match |
She has no chronic problems that force her to miss long stretches of the calendar: 55 matches in an incomplete 2026 season is one of the heavier schedules in the top ten.
Why ankle injuries matter for her specifically
Rybakina's game is built on the serve, and the serve is a push off and a landing on the front foot. Any restriction in the ankle costs first-serve speed more than it costs any other part of her game. That is why her physical team builds its work around ankle and knee stability rather than added muscle - more on the team page.
How the WTA medical protocol works
Tour rules allow one medical time-out per injury: three minutes for an examination by a physiotherapist plus treatment time. If the player cannot continue, a retirement is recorded - the opponent advances, and the prize money and points already earned are kept.
A separate rule governs withdrawals before a tournament begins: pulling out twenty-four hours or more before a first match carries no penalty, while withdrawing after the draw can bring a fine. That is why the decision about the US Open after Cincinnati went to the wire - withdrawing earlier would have removed the option of changing her mind.
Season load and the price of the calendar
Fifty-five official matches in an incomplete season is one of the heavier schedules in the top ten. Add intercontinental travel, four surface changes a year and compulsory WTA 1000 entries, where skipping an event without a medical certificate costs points.
For a player whose game is built on an explosive serve, the joints matter more than the muscles: ankle, knee and shoulder. Every serve is a push, a rotation and a landing on the front foot; across eighty serves in a match the load accumulates quickly.
That shapes how her physical team works: not added mass but joint stability, recovery control between matches and lighter weeks between tournament blocks.
Reading a retirement
A retirement is not the same as a withdrawal, and the difference matters for the record. A player who retires mid-match keeps the prize money and points already earned; the opponent advances with a win recorded against her name. A withdrawal before the match starts leaves no result at all.
Statistically, retirements cluster in exactly the situations Rybakina found herself in: back-to-back mandatory events, a hard surface, and a Grand Slam a week away. Playing on with a compromised joint risks a longer absence than the points are worth.
Her own record shows the pattern clearly: two retirements in 2026, both mid-match, and no pre-tournament withdrawals at all. She enters what she intends to play.
