The two defending champions, Jannik Sinner and Aryna Sabalenka, enter the 2025 Australian Open as favorites to win in Melbourne again.

Alcaraz is already the youngest man in history to win grand slams on the three different surfaces, and he added a second Wimbledon title to his French Open and US Open triumphs in July.
