In her postgame press conference, Pliskova said she had been wary of Osaka's power and had tailored a game plan aimed at neutralizing the U.S. Open champion's unsafe forehand.
"I didn't want to try to overpower her because I think she just has more power than me, so I just wanted to be patient and just to wait for my chances, waiting for my shots", Pliskova said.
The 20-year-old Osaka has signed with the US$500,000 Hong Kong tournament to make her second straight appearance at Victoria Park and was scheduled to compete in this week's Wuhan Open in China.
Osaka has carried the poise and power that saw her overcome Serena Williams in the Flushing Meadows final across the Pacific with her and, helped by eight double-faults from Giorgi, wrapped up the victory in just 72 minutes. Osaka has now lost in the final of this tournament twice, having also been runner-up in 2016.
Slovakia's Magdalena Rybarikova was forced to withdraw due to an upper respiratory illness. But I served really well and that got me out of a lot of trouble today.
Pliskova has spent more time on court than any other player at this tournament despite a first round bye and was once again dragged into a long contest by a dogged Vekic. "But I won, that's important, which means I have a chance to improve again." said the former Wolrd Number one, Pliskova. "I was getting exhausted from the match, so it was not as fast as I wanted to serve".
Seeking to break back, Osaka hit a number of impressive winners against Pliskova's serve, but the fourth seed held firm to close out the set.
"She has basically every shot and she has a really good serve, so I know it will be a very hard match".
"It was important for me to play just two sets and not go to a third one".
Her rally ended up falling just short as Wozniacki served out the match, drawing an error from Osaka on match point to take her first title of the year. That's normal in semi-finals - there are no easy opponents. "For a while it was looking like it maybe could be under two hours, but not really". "She was missing quite a lot today so it was working, so I didn't change anything".
