Carlos Alcaraz is now 20-0 in first-round matches at Grand Slams after opening win at Australian Open

World No. 1 Carlos Alcaraz made a winning start to his 2026 Australian Open campaign on Rod Laver Arena on Sunday night, defeating Australia’s Adam Walton in the first round of the Happy Slam, 6-3, 7-6 (2), 6-2.

It was actually a winning start to his 2026 season, period—he didn’t play any official lead-up tournaments over the last few weeks.

But the Spaniard came out strong on Sunday, cruising through the first set in 34 minutes, bouncing back from 3-1 down to take the second set on a tie-break, then rolling through the third in 32 minutes to close it out.

And with that victory, Alcaraz kept a very impressive stat going—he’s now 20-0 in his career in first-round matches at the Grand Slams.

Alcaraz is just the second man this century to win their first 20 or more first-round matches in a row at Grand Slams, after Rafael Nadal, who won his first 34 before finally losing one to Steve Darcis at Wimbledon in 2013.
