She becomes the third Australian women in the second round alongside Ash Barty and Sam Stosur.

The 21-year-old defeated Hungarian Tímea Babos in three sets 3-6 6-2 6-1 on Tuesday afternoon at Roland Garros. 

It was only Hon's third time of making a main singles draw at a major, with her two previous being at the Australian Open in 2016 and 2019. 

She will now face world No.14 Madison Keys on Thursday, May 30. 

"I was getting frustrated, I've been ranked around here (top 100) but at big tournaments, I hadn't been getting wins," Hon said.

"She's (Keys) one of the best so I'm excited to see what I can do against her."

Unfortunately, fellow Australians Daria Gavrilova and Alja Tomljanovic lost their first-round matches. 

Tomljanovic had the hard task of coming up against the reigning French Open champion Simona Halep. 

The 26-year-old didn't make it easy for the Romanian, stealing a set off her in the second to force a third but Halep sealed her path to the next round in a 6-2 3-6 6-1 victory.

It was sad news for Gavrilova who retired in the second set after she called for a trainer to work on a heavily strapped thigh. 

She was down a set after Serbian Aleksandra Krunic took the first 6-3.

The match resumed but after Krunic successfully drop-shotted her three times in the last game, Gavrilova was almost into tears.

It's doubles action for the Aussies on Wednesday with Ash Barty/Victoria Azarenka coming up against Ajla Tomjanovic/Aleksandra Krunic while Storm Sanders/Miyu Kato face world No.9's Anna-Lena Grönefeld/Demi Schuurs.

Gavrilova is also set to take the court with Greek star Maria Sakkari.
