Corentin Moutet vs Tomas Machac — R64 — Miami Open

Moutet and Machac swapped lopsided sets — a 6-0 opener answered by a 6-1 reply — before a lone break in game three of the decider settled it. The margin was Machac's second serve betraying him at the wrong time: he won 59% of those points to Moutet's 35%, yet handed back 44 unforced errors against 13. In their first meeting, Moutet escapes a set point and a match point along the way and books Sinner next.
