The return of Caroline Wozniacki’s winning smile may be the tournament’s lasting image but the 2016 Toray Pan Pacific Open will also be remembered as Naomi Osaka’s coming out party.

While her talent has never been in doubt, the Japanese teenager has struggled to exhibit it as often as she would like. That all changed during her homeland’s flagship event, as Osaka dismantled Dominika Cibulkova and overpowered Elina Svitolina en route to her maiden WTA final.

Wozniacki – whose own feel-good story promoted her to No.22 – ensured there was no fairytale finish, but she was unable to stop Asian tennis’ star in waiting from becoming the youngest player inside the Top 50.

Many astute observers – including management group IMG – have been keeping a watchful eye on Osaka’s progress for some time. This year alone she has run both Simona Halep and Madison Keys close at majors, and the new World No.47 now looks to have the temperament to make the most of her spectacular shotmaking.

Osaka, though, was not the biggest mover in Monday’s new rankings…

Anastasija Sevastova (+5, No.35 to No.30): Although Sevastova was unable to repeat her US Open upset of Garbiñe Muguruza, by reaching the second round in Tokyo she secured a Top 30 debut. 

Lesia Tsurenko (+27, No.80 to No.53): On the other side of the Sea of Japan, Tsurenko continued the form that took her to the second week of the US Open by dethroning Jelena Jankovic in the final of the Guangzhou International Women’s Open. It was the Ukrainian’s second WTA title and puts her just 52 points away from reclaiming a Top 50 spot.

Lara Arruabarrena (+29, No.90 to No.61): Last week’s other title winner, Arruabarrena, did it the hard way coming back from the brink against Louisa Chirico, then winning a rollercoaster final with Monica Niculescu. This ended a four year wait for a second WTA title and also brought a new career-high ranking.
