Madison Keys vs. Katerina Siniakova — Cincinnati 2026 R32 Match Report
Both Madison Keys and Katerina Siniakova arrived in Cincinnati carrying the same uncomfortable memory: a first-round exit at last year’s US Open.
For Keys, the 31-year-old former major champion, this week has doubled as the start of a North American swing she needs to use well.
Against Siniakova, she made the clearest possible statement about where her game stands right now.
Keys won 6-1, 6-3 in the round of 32, needing barely an hour to do it. She broke Siniakova’s serve four times without facing a single break point of her own, a level of control that left the Czech with almost nowhere to hide.
A few numbers set the tone: Keys won 74 percent of her service points to Siniakova’s 47, and finished with a dominance ratio of 2.06 against Siniakova’s 0.49, more than four times lower.
Madison Keys Breaks Twice to Cruise Through a Lopsided Opener
The first set left little doubt about how the match would go.
Keys held to open, Siniakova leveled, and Keys held again to lead 1-2. From there, she took total control: a break for 1-3, a hold for 1-4, and a second break for 1-5, before closing the set out with a final hold, 6-1.
Siniakova managed a single hold of her own in the entire set, sandwiched between two breaks that Keys barely had to work for. It was a set built on returns as much as serves, Keys finding depth and pace that Siniakova simply couldn’t answer.

A Return Game That Left Siniakova With No Answers
Across the match, Siniakova had only one real window into Keys’s serve. She created three break points, all in the second set, but Keys saved every one of them. Her control was that complete.
The scoreline points to total domination, and the underlying numbers back it up without much complication this time. Siniakova’s return rating of 51 was a fraction of Keys’s 204.
Keys’s own serve did plenty of damage too.
She won 79 percent of her first-serve points and finished with 13 winners to Siniakova’s six, while committing far fewer unforced errors, 12 to 22.
On pressure points, Keys won seven of twelve to Siniakova’s five, a smaller gap than the rest of the match but still enough to confirm which player controlled the moments that mattered.
Two Players Chasing the Same Redemption
The shared history between these two goes beyond Tuesday’s scoreline. Both were eliminated in the first round of last year’s US Open, Keys in a marathon three-setter to Renata Zarazua and Siniakova in straight sets to Hailey Baptiste.
Neither has played an especially heavy hard-court schedule since, and both arrived in Cincinnati looking to bank ranking points before the North American swing reaches its biggest event.
For Keys, that search has included a mix of promising and frustrating results this year, from a run to the Australian Open fourth round to an early exit in Toronto against Marta Kostyuk.
Cincinnati now offers her the kind of deep run that could meaningfully reshape her position heading into New York.
Wang Xiyu or Svitolina Awaits
Keys’s win sets up a round-of-16 meeting with the winner of Wang Xiyu and Elina Svitolina, a step up in competition after an afternoon in which Siniakova rarely threatened her.
For Siniakova, the singles disappointment comes with a reminder of where her game still ranks at the very top. She remains the WTA’s world No. 1 in doubles, a position built on one of the best seasons of her career.
Reunited with regular partner Taylor Townsend, she won back-to-back WTA 1000 titles at Indian Wells and Miami to complete the Sunshine Double. She then added a third straight 1000 crown in Madrid, beating Mirra Andreeva and Diana Shnaider in straight sets in the final.
She reinforced that No. 1 spot again just last week, winning the Toronto title alongside Zhang Shuai without dropping a set.
At the 2026 US Open, she will be back with Taylor Townsend.
