Eva Lys became the first lucky loser to reach the last 16 of the women's singles at the Australian Open after she beat Jaqueline Cristian.

Australian Open history was made at Melbourne Park on Saturday, as lucky loser Eva Lys beat Jaqueline Cristian.

Lys hit back to beat world number 82 Cristian 4-6 6-3 6-3.

In the process, she became the first lucky loser to reach the fourth round of the women's singles draw at the Australian Open.

The German's reward for her history-making victory will be a meeting with world number two Iga Swiatek, who made light work of Emma Raducanu in her third-round match.

Elena Rybakina, meanwhile, overcame a back injury to defeat Dayana Yastremska 6-3 6-4 at John Cain Arena.

Rybakina had to receive treatment during the first set, but recovered to claim a third consecutive straight sets win to continue her excellent campaign.

"Honestly I didn't know how it was going to go because it came all of a sudden," said Rybakina, a beaten finalist at the Australian Open in 2023.

"I didn't expect it and it was not easy, I knew that it would be very difficult for me to stay long in the rallies, I was trying to play aggressive and sometimes risk a little bit more – really happy that it went my way in the end."

Asked if her pain had eased, the 2022 Wimbledon champion said: "Not really, so I am going to see my physio and he will hopefully do some magic."
