ATP Washington 🇺🇸 Final Results
Jannik Sinner (5) d Mackenzie McDonald 7-5 4-6 7-5
In a match edging just under 3 hours, it was the Italian to overcome the pressure of the crowd, and the pressure of Mackie's return of serve in a great battle of youngsters. Sinner just had that bit more oomph that McDonald could not match on gruondstrokes. This was not just groundstrokes, but serve % well. McDonald was excelling in return of serve, but could not hold his serve better than Sinner. Sinner serving 9 aces, and creating 21 break point opportunities. McDonald did well to save 16 of those break points, but not well enough to convert enough of his own (4/11). An entertaining match none-the-less!
