The WTA circuit has seen only one repeat winner in 13 tournaments this year and for Japan's Naomi Osaka, who is fast emerging as the next dominant force in women's tennis, the results underline the depth of talent on the Tour.

Russian Daria Kasatkina, who bagged the Phillip Island Trophy in Melbourne last month, became the first two-time winner on the Tour this year on Sunday after the 23-year-old's triumph in the St. Petersburg Ladies Trophy final.
