Having tasted her first Grand Slam success at the U.S. Open last year, Naomi Osaka says she now has a "weird" feeling of wanting more after progressing to her first Australian Open semifinal on Wednesday.
Osaka was just 20 when she became Japan's first Grand Slam singles champion by beating Serena Williams 6-2 6-4 in a controversial U.S. Open final in September.
She remained on course to add another Grand Slam title to her resume after blowing away Ukrainian Elina Svitolina 6-4, 6-1 on Wednesday to set up a semifinal with Czech Karolina Pliskova in the year's first Grand Slam.
