World number six Karolina Pliskova has withdrawn from the Sydney International with a left thigh injury, tournament organisers said Sunday. The Czech, who was the fourth seed for the Sydney event, demolished France's Alize Cornet 6-0, 6-3 to win the Brisbane International on Saturday.

As her withdrawal came before the start of the first match, Italian Roberta Vinci as the next eligible seed took Pliskova's open spot and a qualifier/lucky loser would come into the draw, organisers said.
