Ugo Humbert vs Gabriel Diallo Prediction

Diallo’s season hasn’t quite gone to plan, but he showed some promise and inspiration in his last tournament in Indian Wells, winning two matches and losing out in a tight one to Auger-Aliassime. He’s carried that momentum to Miami and was flawless in beating Yibing Wu. Humbert’s form has been dire and dismal since Rotterdam, and it’s tough to see him changing that here.
