Understandably, given the potentially seismic shift at the top of the rankings, Karolina Pliskova’s mightily impressive progress through the draw at last week’s Western & Southern Open went largely unnoticed. Unnoticed that is until she scuppered plans for Angelique Kerber’s World No.1 coronation with a flawless display in the final of the Premier 5 event.

Having enjoyed a breakthrough season in 2015 – reaching six finals and threatening to qualify for the BNP Paribas WTA Finals Singapore presented by SC Global – Pliskova has found success harder to come by this time around. There have been flashes of her explosive brilliance – most notably in Indian Wells, where she reached the last four, and on the grass of Nottingham and Eastbourne – but consistency has remained elusive.  

This past weekend, the Czech proved once more that her place at tennis’ top table is very much warranted, outplaying Garbiñe Muguruza then Kerber to take home the sixth and most prestigious title of her career. The result bumps Pliskova several places up the rankings from No.17 to 11. Not only is Pliskova now certain to be among the leading 16 seeds for the US Open, she is also within touching distance – a measly 55 points, to be precise – of reclaiming the Top 10 spot she held briefly last season.

A more pressing concern is fulfilling her undoubted potential at the Grand Slams, where she is yet to make it beyond the third round. Her ranking rise has aided hopes of a good showing at the US Open, which begins next Monday.

Pliskova, though, was not the only player to receive a potential seeding boost.

Timea Babos (+8, No.41 to No.33): Also performing well in Cincinnati was Babos, whose first quarterfinal at an event of this stature was rewarded with a career-high ranking and a possible seeding at the US Open.

Alizé Cornet (+11, No.58 to No.47): It has been a testing campaign for Cornet, injuries precipitating a slide down the rankings and, in Cincinnati, forcing her to qualify for a WTA event for the first time since April 2012. She came through the test, going on to upset Kiki Bertens in the first round to edge back into the Top 50.

Alison Riske (+11, No.70 to No.59): Another player to come through qualifying was Riske, and while she was unable to capitalize on a bright start to upset Svetlana Kuznetsova in the second round, the points earned ensure she continues to close in on a return to the Top 50 for the first time since last September.

And finally…
Strictly speaking, Sania Mirza did not move up in the rankings last week, but by outperforming former partner Martina Hingis in Cincinnati she now assumes sole ownership of the doubles No.1 ranking. It is her 70th week on top – only Gigi Fernandez (80 weeks), Paola Suarez (87), Sara Errani (87), Roberta Vinci (110), Arantxa Sánchez-Vicario (111), Natasha Zvereva (124), Lisa Raymond (137), Cara Black (163), Liezel Huber (199) and Martina Navratilova (237) have been World No.1 for longer.
