Ash Barty has hailed Iga Swiatek, her successor as the world No.1, declaring there's no-one better to take over the top spot in women's tennis than her young Polish friend.
Swiatek was left reflecting on her "dream come true", becoming just the 28th woman - and first from her country - to head the WTA rankings after beating Viktorija Golubic 6-2 6-0 in the second round of the Miami Open.
