Halep withdraws from Sydney International

French Open is the goal – Djokovic

Halep, who began her 2015 campaign with victory at the Shenzhen Open, is suffering from gastroenteritis and will skip the Sydney event in a bid to be fit for next week's Australian Open.

The Romanian's place in the draw has been taken by American Nicole Gibbs.

Halep is the second high-profile withdrawal from the tournament, with Caroline Wozniacki pulling out due to a wrist injury.
