Last year’s runner-up Alexander Zverev begins his 2026 Australian Open campaign. The third seed faces unseeded Gabriel Diallo in round one. Will we see a big upset in the first round? Read our match prediction below.
The winner of this match will take on either Alexei Popyrin or Alexandre Muller in round two, both unseeded.
Zverev was beaten by Jannik Sinner in the 2025 final. The German also made it to the semi-finals of this outdoor hard court Grand Slam in 2024. He’s won 11 of his last 13 matches in this tournament and has not been beaten in round one since 2016.
Last year saw Zverev win 57 matches but only win one title and that was on clay.
So far in 2026, he’s only played in the United Cup beating Tallon Griekspoor but losing to Hubert Hurkacz.
Gabriel Diallo is 41st in the live rankings, eight places below the career-high he set in August of last year. The Canadian was consistent in Grand Slam tournaments last year. Each of the four saw him defeated in the second round.
He’s only won one of his three matches played this year. Five of his last seven matches have been lost.
We tip Zverev to win in straight sets.
