Right in the first round, the two players who were in the top 5 of the world, Androy Rubleev and Dominic Thiem had to compete together. RubleV is significantly highly appreciated for its No. 5 seed position.

Dominic Thiem only ranked 98th on the ATP rankings and only attended the Australian Open 2023 thanks to the special capacity from the organizers. Despite causing difficulties for RubleV in the first gaming game (owning 4 opportunities to win the break), the player comes from Austria to be completely 'inferior' in Set 1. Thiem continuously takes 2 breaks, not once breaking the opponent's game and losing quickly with a score of 2-6.
Set 2 is more balanced but that balance comes only in the first half. The other half witnessed RubleV's better. The 25-year-old player won the break in the 9th game and takes 5-4 leading. Seed No. 5 Win is 40-15 in the next game to close the set with a score of 6-4.
Losing set 2 made Dominic Thiem mentally. He only won 2 games of Set 3. In the opposite direction, RubleV had 2 game breaks and defeated a 4-year-older than himself with a score of 6-2 as set 1.

This is the second time in the thiem career was eliminated from the first round of Australia. The first time this happened was in 2015.
With RubleV, the 25 -year -old player completed the first step in concretizing the goal further further than the quarterfinals. The opponent of the 6th seed in the second round is the player who won the Max Purcell (205) vs Emil Ruusuvuori (46).
