It leaves Australia with just one hope in the men's singles draw at Roland Garros, with Nick Kyrgios sitting out the event due to COVID-19.

On the women's side of the draw, Dasha Gavrilova and Astra Sharma are the two remaining hopes after they both won their respective first-round matches.
Both women will play on Wednesday night (AEST).
