João Fonseca will not play his third round in Cincinnati. The Brazilian, ranked 26th in the world, withdrew on Tuesday ahead of his match against Australia's Christopher O'Connell after feeling discomfort on the left side of his abdomen during practice the previous day. With the US Open less than two weeks away, the timing could hardly be worse.

The player explained the decision himself. "Today during practice I felt a slight discomfort on the left side of my abdomen. After undergoing tests, my team and I decided to withdraw from the Cincinnati Open to recover as quickly as possible." The tone is reassuring, the wording careful. No timeline has been given, and the exact nature of the problem has not been disclosed.
O'Connell therefore moves into the last 16 without hitting a ball. For Fonseca, the halt stings all the more because he had opened his week convincingly two days earlier, beating Botic Van De Zandschulp 6-4, 7-6(7) in a shade under two hours. The second set turned on a tight breaker, won 9 points to 7, the kind of passage that says as much about a player's nerve as about his tennis.
A SEASON THAT CHANGED HIS STANDING
The withdrawal lands in the middle of a 2026 campaign that has redrawn the Brazilian's status. Nineteen wins from thirty-two matches, but above all a set of results that owe nothing to luck. At Roland-Garros he knocked out Novak Djokovic in the third round before reaching the quarter-finals, a fortnight that marked the moment the wider public stopped seeing him as a prospect and started treating him as an opponent. In Montreal, days before Cincinnati, he saw off Stefanos Tsitsipas and then Casper Ruud before falling to Ben Shelton.
That kind of run carries a cost. A player discovering the rhythm of Masters 1000 events and Grand Slams at this speed absorbs a workload his body has never met. Fonseca turns twenty in three days. The physical question, long a secondary matter in his case, is becoming something his team will have to watch closely.
THE NEW YORK DEADLINE
It is the US Open, inevitably, that gives this withdrawal its weight. The tournament begins in under two weeks and Fonseca will arrive with a standing he did not hold a year ago, that of a seeded player capable of troubling anyone on hard courts. Skipping Cincinnati costs him match practice in conditions close to those of Flushing Meadows, but hands him ten days to heal.
The trade-off is a familiar one and rarely debatable: better to turn up short of rhythm than short of fitness. Abdominal problems carry the awkward habit of striking the serve directly, a stroke that loads the core on every strike. A player who cannot serve freely on hard courts loses far more than a few miles per hour, he loses the foundation of his attacking game.
WHAT TO WATCH
Nothing at this stage suggests his New York campaign is in danger, and nobody in his camp has hinted at it. The phrasing used, withdrawing in order to recover as quickly as possible, points to precaution rather than alarm. Still, the silence on any timeline leaves room for every reading, and the coming practice days will say far more than any statement.
Cincinnati, meanwhile, carries on without one of its most anticipated names. O'Connell inherits an unexpected place in the last 16, and the men's draw loses a tie many had circled. Brazilian tennis, without a flag-bearer of this stature for a long time, will simply hold its breath until the first exchanges in New York.
