He then entered the 2023 Australian Open as a lucky loser after the withdrawal of David Goffin and won his first round match, defeating fellow qualifier French Laurent Lokoli, after saving a match point in the third set. He then defeated 12th seed Alexander Zverev in the second round. He became the fifth player to make it as a lucky loser to the third round; the furthest a lucky loser had made it at this Major is the fourth round (Stéphane Robert in 2014). As a result he moved up 25 positions back into the top 100 to a new career-high singles ranking of No. 83 on 30 January 2023.
