Heather Watson celebrates winning her second round match over Ksenia Pervak at the Australian Open

Heather Watson has produced another remarkable display at the Australian Open, coming back from three match points down to beat Ksenia Pervak.

Fans thought the British number one was on her way out. At one point, she was trailing her opponent by a set and was losing 6-3 in the second set tie-break.

But Watson battled back to win 4-6 7-6 (9-7) 6-2 after three hours and two minutes.

She will now play in-form fourth seed Agnieszka Radwanska in the last 32.
