Ash Barty has detailed the immense satisfaction of silencing her doubters as Iga Swiatek savours being crowned tennis's year-end world No.1 for the first time.
Swiatek was on Wednesday officially declared the WTA's 17th different year-ending No.1- succeeding Barty - following a phenomenal eight-title, two-slam season also featuring a 21st-century-best 37-match winning streak.
