Tommy Paul vs Adrian Mannarino — R64 — Miami Open

Tommy Paul needed a clean third set after letting the second slip, and the breaks in games six and ten settled it. The separator was first-serve efficiency: Paul won 76% of his first-serve points to Mannarino's 61%, a 15-point gap that held even as the Frenchman broke twice to take the second 6-2. Three match points came and went before Paul closed the 6-4 third, reversing an H2H that Mannarino led 2-1. Raphael Collignon is next.
