Wozniacki revels in title defence

Wozniacki, who knocked out Garbine Muguruza in the semi-finals, went up against Russian Anastasia Pavlyuchenkova in Sunday's final in Tokyo looking to become the seventh woman to successfully defend the title.

The Dane, who is a two-time US Open finalist, romped through the first set, winning 6-0, but the second set was a much tighter affair as her opponent put on a much stronger showing.

However, it was the 27-year-old from Odense who won the set 7-5, picking up her 26th career title and ensuring she continued her run of having won at least one WTA tournament every year since 2008.

It also ended a frustrating period for Wozniacki, who had lost her previous six finals in 2017, and she admits it was a big relief to finally get the job done after so many near-misses.

"It was my seventh final this year and obviously after a while it gets harder and harder," she said. "I've won here in the past and it has great memories for me so I'm happy I was able to stay focused and aggressive."
