Updated Aug. 18, 2026: Three entries change. Elina Svitolina, the world No. 9, withdrew on Tuesday afternoon ahead of her third-round match against Xiyu Wang with a right ankle injury she sustained in Toronto and aggravated in the second round here. Wang advanced by walkover to face Madison Keys. Svitolina said she had been advised by doctors to rest, and gave no timeline beyond that — full report here. Joao Fonseca has withdrawn mid-tournament, pulling out before his third-round match against Christopher O’Connell after feeling discomfort on the left side of his abdomen during practice. He said tests were carried out and that he and his team decided to withdraw in order to recover as quickly as possible. No timeline was given and no assessment of his US Open availability has come from the player or his team. O’Connell advances to the last 16 without playing. Separately, the Belinda Bencic doubt logged below has resolved: she retired from her second-round match with a right hip injury, which the tournament’s draw sheet records as a retirement rather than a withdrawal.
Updated Aug. 12, 2026: Belinda Bencic is a new doubt rather than a new withdrawal, and the distinction matters here. She pulled out of her Toronto quarterfinal against Coco Gauff shortly before it was due to start, describing a pinching hip that painkillers, taping and a warm-up had all failed to settle, and saying she could not move well enough to compete. She remains the No. 12 seed in Cincinnati with a first-round bye and has not withdrawn from this tournament. She had also said earlier in the week that a lingering problem after Wimbledon left her unsure whether she would play Toronto at all. Nothing has been announced by the player or the tournament, so the running count is unchanged at thirteen. Separately, Holger Rune, who is on the list below, has stated that he has not withdrawn from the US Open, contradicting a wave of reports this week that said he had — the full account is here. His absence from Cincinnati is unaffected.
Updated Aug. 11, 2026: Qualifying begins this morning and the singles draws are made at 3 p.m. ET, which is the point at which this list stops governing replacements. Until the draw, a vacancy is filled from the alternate list in ranking order; after it, a late withdrawal is filled by a lucky loser from qualifying. No new withdrawal has been confirmed on either entry list overnight. The running count stands at thirteen, seven men and six women, correcting the split published here yesterday. Gabriel Diallo remains a doubt rather than an absence, unreplaced and unconfirmed by player or federation.
Updated Aug. 10, 2026: No further withdrawals have been filed on either entry list overnight, with qualifying due to begin. The running count on this page has been reconciled: thirteen players are confirmed out, seven men and six women. Gabriel Diallo, who retired from his second-round match in Montreal with a leg injury, is not included in that figure. He has not been replaced on the men’s entry list and neither he nor Tennis Canada has confirmed a withdrawal, so he is carried here as a doubt rather than an absence.
Updated Aug. 9, 2026: Karolina Muchova is out of the women’s draw, with Simona Waltert taking her place. Muchova, the Wimbledon runner-up, underwent surgery days after that final and has not named the injury. She has said she expects to be ready for the US Open, but she will arrive in New York without a competitive hard-court match, having also missed Toronto. That takes the running total to fourteen across both fields.
Updated Aug. 9, 2026: Jannik Sinner has withdrawn from the Cincinnati Open with a right knee injury. The world No. 1 announced the decision Sunday, saying he was not ready to compete and was turning his attention to the US Open. He was runner-up here last year and has not played since winning Wimbledon on July 12. His withdrawal takes the top-ranked man out of a draw that had already lost the defending champion. Full story here.
Updated Aug. 9, 2026: Two further withdrawals have been confirmed on the entry lists. Ethan Quinn is out of the men’s draw, with Lorenzo Sonego taking the place, and Jacqueline Cristian is out of the women’s draw, replaced by Maria Timofeeva. That takes the running total to twelve across both fields.
Updated Aug. 8, 2026: Jasmine Paolini has withdrawn from the Cincinnati Open, where she was runner-up last year. She announced it herself on Instagram on Friday. Taylor Townsend has taken her place in the main draw, moving in on her ranking and returning to the tournament the wild card she had been awarded on Aug. 3.
Updated Aug. 7, 2026: Holger Rune has withdrawn from the Cincinnati Open, and Daniel Mérida moves out of qualifying into the main draw in his place. Lorenzo Sonego was next in line and has since taken Ethan Quinn’s place.
The last significant tune-up before the US Open is going ahead without a growing share of the players it was built around. Thirteen men and women have come out of the Cincinnati Open singles fields since the entry lists were published, seven from the men’s draw and six from the women’s, with Gabriel Diallo a further doubt who has not yet been replaced. The heaviest losses at the top have come on the men’s side.
Rune came out on Aug. 7. The Dane has not played a competitive match since rupturing his left Achilles tendon at the Stockholm Open in October 2025, and Cincinnati had been the last realistic staging post for a comeback before New York. He had already come out of Hamburg, Roland Garros, Queen’s, Wimbledon and Montreal while working back from surgery, each time stopping short of a firm return date. He has not set one now either. Mérida, who had been expected to play qualifying, takes the vacated place.
Until Sunday the largest absence had been the defending champion.Carlos Alcaraz withdrew on Aug. 4 with the right wrist injury that has kept him off the tour since the Barcelona Open in April. He won the title here last year when Jannik Sinner retired in the first set of the final, and he was due to defend 1,000 ranking points. Mattia Bellucci replaced him in the field. With Cincinnati gone, the ATP 250 in Winston-Salem is the only tune-up left on his calendar before New York.
Three men had already gone before Alcaraz. Alexander Bublik, Alejandro Davidovich Fokina and Sebastian Korda all came out of the men’s field, with Marton Fucsovics, Adam Walton and Valentin Royer taking their places. Korda has since had surgery. Gabriel Diallo is also expected to miss the tournament after retiring from his second-round match in Montreal with a leg injury, though Tennis Canada has not given a timeline for his return.
The women’s field has lost six, Karolina Muchova the most recent. Victoria Mboko and Hailey Baptiste are both out for the entire North American hard-court swing with knee injuries, Mboko with medial collateral ligament damage sustained in a fall at Queen’s Club in June and Baptiste with an anterior cruciate ligament and meniscus injury from the second round of the French Open. Tamara Korpatsch and Tatjana Maria replaced them. Jacqueline Cristian also came out, replaced by Maria Timofeeva.
The fourth is Emma Raducanu, who is recovering from a stress fracture and has also been left off the US Open entry list. Maya Joint took her place in Cincinnati.
Jasmine Paolini is the fifth. The Italian reached the final here last year and was defending 650 points. She has not played since the Wimbledon quarter-finals and had already skipped Washington and Toronto with a left foot injury. She confirmed the Cincinnati withdrawal herself on Instagram on Friday, saying the focus is on being ready for the US Open. It is mathematically possible she leaves the top 20 before New York, though that turns on results below her rather than on the withdrawal alone.
What remains is still a deep field, though the women’s draw has now lost Muchova, Paolini and Mboko. Aryna Sabalenka, Elena Rybakina, Jessica Pegula, Coco Gauff, Mirra Andreeva and Iga Swiatek are all entered, with Swiatek defending the title. On the men’s side Alexander Zverev, Felix Auger-Aliassime, Taylor Fritz and Ben Shelton are all in, and Novak Djokovic returns for the first time since winning the title in 2023.
Jack Draper is a separate case. He remains on the entry list and has not withdrawn, but his participation is in doubt after he lost his opening match in Montreal while hampered by a recurrence of the bone bruising in his left arm that had already cost him most of the first half of the season. He holds a main-draw wild card, and reports since Montreal have him returning in Cincinnati, though no statement from the player or his team has confirmed it. Until a withdrawal is filed he counts as entered, not absent.
Replacements are drawn from the alternate list in ranking order until the draw is made. Once the draw is out, a late withdrawal is filled by a lucky loser from qualifying rather than by the next alternate, which is why the identity of a replacement can change depending on how close to the draw ceremony a player pulls out. Qualifying runs Aug. 11-12 with 48 men and 48 women competing for 12 main-draw places each.
The tournament opens with Community Weekend on Aug. 8-9 at the Lindner Family Tennis Center in Mason, Ohio. The main draw begins Aug. 13 and runs through Aug. 23. The US Open main draw starts Aug. 30.
Every withdrawal at this stage carries a second consequence. Points not defended in Cincinnati come off a player’s ranking on the Monday after the tournament, and US Open seeding is set from the rankings of Aug. 24. Alcaraz and Swiatek are the two defending champions here, and only one of them is playing. This page will be updated as further withdrawals are confirmed.
