2025 runner-up has an uphill battle against Canada’s rising star.
No. 3 seed Alexander Zverev faces a stern test in the Australian Open 2026 Round of 128 on Sunday. The German powerhouse will be up against Canada’s Gabriel Diallo, who just missed out on a seeding in Melbourne Park. The winner of this clash is set to battle either Alexei Popyrin or Alexandre Muller in Round-2. Can last year’s runner-up navigate his demonic draw to make another deep run in the first major of the campaign?
Having represented Germany at the United Cup 2026, Zverev finished with one win and one loss. The World No. 3 went 57-25 in 2025, including a solitary championship run at the BMW Open in Munich. In comparison, Diallo reached a career-high ranking of No. 33 in the world after winning the title in ‘s-Hertogenbosch. The 24-year-old is currently the third best player from his country. At the recently concluded Hong Kong Tennis Open, Diallo was eliminated in the Round of 16.
According to the tennis betting odds, Alexander Zverev (-770) is the favorite to win this opening round encounter, according to BetMGM. On the other hand, Gabriel Diallo (+500) is the underdog in the pre-match moneyline. Here’s how we are betting on this highly anticipated contest on Rod Laver Arena, including our best bets, supporting odds and a set-score prop for bigger prices.

Over the last two editions of the Australian Open, Alexander Zverev has reached the semis and final respectively. Along with the urge to protect his ranking, the German will have the added pressure of defending 1,300 points this year. In the 2025 summit clash, Sascha failed to generate a single break point on the Jannik Sinner serve. While he could face similar troubles against Diallo, the room for error is more.
One of the areas where the World No. 41 can attack Zverev is on the defensive end. During high stakes points at 30-30 or 30-40, the German tends to go into a shell and play safe. Provided Diallo can use the crowd to eke out some extravagant points and build some momentum, this duel has all the ingredients to become an instant classic. Yet, we are backing Zverev to win in four sets on Sunday.
The head-to-head record between Alexander Zverev and Gabriel Diallo is currently 0-0. The Australian Open 2026 Round of 128 will be their first tour-level meeting.
