Murray, Sinner start Open prep in Adelaide

Andy Murray will start preparations for a 15th Australian Open in South Australia for the first time, lining up at the Adelaide International.

The veteran Scotsman has entered along with Italian young gun Jannik Sinner, who is ranked world No.15, with play in the week-long tournament getting underway on January 1.

Adelaide will host back-to-back combined WTA 500 and ATP 250 tournaments, with the second editions from January 9-14.

Former world No.1 Murray, a five-time finalist at Melbourne Park, said he was looking forward to a change in his Open build-up.

"Playing at the Adelaide International for the first time is something I'm looking forward to," 35-year-old Murray said in a statement.

"The crowds in Australia love their tennis and they've always been very supportive.

"I've been working hard in the off season and the Adelaide International will be great preparation for the Australian Open."

Two-time Australian Open champion Victoria Azarenka will headline the women's field for both tournaments, with dual Wimbledon champion Petra Kvitova to join the line-up in the second week.
