World No. 1 Ash Barty and US Open champion Emma Raducanu will be the star attractions at a new tennis event in Sydney next month.

The Sydney Tennis Classic will be held at Sydney Olympic Park from January 9 to 15.

Nineteen of the world’s top 24 women will compete in the tournament, including world No. 3 Garbine Muguruza, former world No. 1’s Angelique Kerber and Simona Halep, Roland Garros 2020 champion Iga Swiatek and Tokyo 2020 Olympic gold medallist Belinda Bencic.

Former US Open champion Dominic Thiem will head the ATP event along with Australian No. 1 Alex de Minaur, David Goffin and Kei Nishikori.

“To see nineteen of the world’s top 24 women, and four of the world’s top 20 men, compete at the Sydney Tennis Classic the week before the Australian Open is fantastic news for Sydney tennis fans,” tournament director Paul Daly said.

“We’re also delighted to see Ash Barty and Alex de Minaur return to Sydney Olympic Park, they’ve both played great tennis here and will have special memories of the venue. It will be a special week of competition.”
