Day Three of the 2026 Australian Open was a grueling test of endurance, featuring high-stakes drama and a record five five-set thrillers. While the defending champion looked as untouchable as ever, the “Melbourne Heat” began to claim its victims, with veteran seeds and rising stars alike falling in a chaotic end to the first round.
The Sinner Machine Rolls On
Defending champion Jannik Sinner extended his dominance at Melbourne Park to 15 consecutive wins with a clinical performance against France’s Hugo Gaston. Sinner was leading 6-2, 6-1 when Gaston was unfortunately forced to retire due to an injury.+1
Despite the short match time of just 68 minutes, Sinner showed off the technical tweaks he made to his serve during the off-season. He struck seven winners in the second set alone and faced only three break points the entire match—all of which he saved with ease. The world No. 2 looks perfectly poised to become only the second man this century to win three Australian Open titles in a row.+2
Shelton Wins the “Battle of the Southpaws”
In one of the most anticipated matches of the day, 8th seed Ben Shelton outlasted Ugo Humbert in a high-tension clash on Rod Laver Arena. In a match defined by big serves and high-pressure tiebreaks, Shelton secured a 6-3, 7-6(2), 7-6(5) victory.+1
The turning point came in the third-set tiebreak, where Shelton roared back from a 3-0 deficit to seal the win. His ability to produce aces at critical moments proved why he is a dark horse for the title this year.
The Marathon Men: Five-Set Madness
Monday was arguably the most competitive day of the tournament so far, with five matches going the distance. Most notably, American qualifier Nishesh Basavareddy pulled off a massive upset by outlasting home favorite Christopher O’Connell in a 4-hour, 8-minute epic.+1
Other survivors of the five-set “furnace” included Karen Khachanov, Jakub Menšík, and Sebastian Baez, all of whom had to dig deep into their physical reserves to book a spot in the second round.
