Top seed Caroline Wozniacki has withdrawn from the Citi Open due to a leg injury.

The world number two was due to face Anhelina Kalinina in the final match on the newly named John A. Harris Grandstand on Tuesday.

Wozniacki will not start her hard-court season in Washington, though, after suffering an injury setback.

Lucky loser Ysaline Bonaventure will instead face Kalinina in the first round in the absence of the Australian Open champion.

Wozniacki has not played since suffering a shock defeat to Ekaterina Makarova in the second round of Wimbledon at the start of July.
