Adolfo Daniel Vallejo vs Gael Monfils prediction

The Gael Monfils farewell tour stops at the US Open with a first-round clash against Adolfo Daniel Vallejo.

The veteran Frenchman has already wowed the New York crowd alongside wife, Elina Svitolina in the mixed doubles, but it will be a big-ask for him to pull off a shock to extend his stay against Adolfo Daniel Vallejo.

The rising Paraguayan star is knocking on the door of the top 50 and has looked sharp on hardcourts in this north American swing.

That will allay fears he is only a danger on clay courts and while La Monf is more than capable of making this a lengthy battle, it’s a tall order for anything beyond that given his lack of positive results this year.
