Alex de Minaur vs Gabriel Diallo prediction

Alex de Minaur is the top seed at Queen’s Club, and he will be hoping to win the event for the first time, with the Australian having lost in the final to Carlos Alcaraz three years ago. His grass court season began at the Libema Open last week as he advanced to the final, but despite being viewed as the favourite for the title, he lost to Kamil Majchrzak in three sets.

De Minaur faces Gabriel Diallo in round one. Diallo was the defending champion at the Libema Open, but he lost in the first-round to Adrian Mannarino. The Canadian has struggled with injury and a loss of form this season, and he is now down to 88 in the live rankings. Overall, he has lost seven of his last eight matches on the tour.

De Minaur leads the head-to-head 2-0. This is likely to be a comfortable win for the Australian against an out-of-form Diallo.
