It was business as usual for Iga Swiatek on Friday afternoon, with the pole dispatching Marta Kostyuk in straight sets to keep her Cincinnati Open campaign alive.
Swiatek faced a little bit of unnecessary drama versus French qualifier Varvara Gracheva in her opening match on Wednesday, spurning a 5-2 lead in the second set and five match points before eventually prevailing in three sets.
But, against the 15th seed, the world No 1 had a much smoother time of things.

Kostyuk broke in the very opening game but was unable to match Swiatek’s consistency after that point, and the five-time Grand Slam winner picked up a comfortable 6-2, 6-2 victory to become the first woman to seal a place in the last eight.
Swiatek hit some notable milestones with her emphatic victory – as now seems commonplace any time the 23-year-old wins a match.
This is now her sixth WTA 1000 quarter-final of the season, only failing to reach the last eight in Miami, when she lost in round four, and at last week’s Canadian Open – where she did not play.
In the past decade, only one player has reached more WTA 1000 quarter-finals in an individual season – herself in 2023, where she reached seven WTA 1000 quarter-finals.
With WTA 1000 events in Beijing and Wuhan coming later in the season, Swiatek is well-placed to eclipse her own personal best.
It is also a 14th straight match win for her at WTA 1000-level, having won Madrid and Rome back-to-back earlier in the year.
That is the second-longest streak by any player since she made her first WTA 1000 appearance in 2019 and, once again, it is her own record she is now potentially in line to break.
She won 23 straight matches at this level in her dominant 2022 season, spanning from Doha to the Canadian Open.
Swiatek has now also reached 13 WTA 1000 quarter-finals across the past two seasons, with Agnieszka Radwanska’s record of 14 across 2012-2013 now under threat.
The world No 1 will face an intriguing quarter-final next, either against fifth seed Jasmine Paolini or teen sensation Mirra Andreeva.
However, with the likes of defending champion Coco Gauff and Elena Rybakina already out of the tournament, she will likely fancy her chances of claiming a first Cincinnati title.
