World No.1 Ash Barty produced a clinical masterclass of ball striking and placement to beat Elena Rybakina 6-3, 6-2 on Friday and advance to the Australian Open fourth round.

With numerous fans wearing bright pink “Barty Party” T-shirts in the stands of Rod Laver Arena supporting her, the 23-year-old Barty had relatively little trouble against the 20-year-old from Kazakhstan.

A tearful but happy Caroline Wozniacki headed into retirement after a 7-5, 3-6, 7-5 third-round defeat at the hands of Tunisia’s Ons Jabeur ended her participation here and her 16-year career.

The 29-year-old said last year that Melbourne Park, where she won her lone Grand Slam title two years ago, would be the site of her final outing as a professional.

“I’d like to thank the fans, the support we feel on court is really amazing. Also the support I’ve had my from family, and especially my dad, who has coached me all those years,” Wozniacki said, smiling through the tears.

“I usually don’t cry, sorry, those are the special moments I’ll remember. It’s been really amazing, a great ride.”

Roger Federer overcame local battler John Millman 4-6, 7-6 (7-2), 6-4, 4-6, 7-6 (10-8) in a thriller. The 20-time Grand Slam champion made 82 unforced errors to go with 62 winners, as he went toe-to-toe with the world No. 47 over more than four hours to secure his 100th Australian Open match win.

Defending champion Novak Djokovic put on an impeccable serving display against Japanese Yoshihito Nishioka to canter to a 6-3, 6-2, 6-2 win in the third round, staying on course for a record-extending eighth title at Melbourne Park.

Canadian Milos Raonic served and volleyed with precision to bundle Greek sixth seed Stefanos Tsitsipas out with a 7-5, 6-4, 7-6 (7-2) victory in the third round.

Former Australian Open runner-up Marin Cilic rolled back the years to outlast ninth seed Roberto Bautista Agut over five sets and book a spot in the round of 16.

The 31-year-old unseeded Croatian won 6-7 (3-7), 6-4, 6-0, 5-7, 6-3 at the Melbourne Arena.

Meanwhile, India’s Divij Sharan and his New Zealand partner Artem Sitak were knocked out of the men’s doubles competition after going down in straight sets to Bruno Soares and Mate Pavic.

Sharan and Sitak lost to the Brazilian-Croat pair 6-7, 3-6 in a second round match that lasted one hour and 17 minutes.
