Hubert Hurkacz vs Marcos Giron — R128 — Canadian Open

The first-serve gap did the sorting. Hubert Hurkacz won 90 percent of points behind his first delivery to Marcos Giron's 67 and out-aced the qualifier 16-2, though the one break he surrendered came in game 10 of the second, Giron converting for 6-4. The American stayed level in the second-serve exchanges, 62 percent to 61, but took just 6 of 50 first-return points, and Hurkacz's break in game 2 of the third, for 2-0, settled the decider. One hour, 53 minutes in, the Pole — entered on a protected ranking — opened his Canadian Open with a third win in as many meetings on record against Giron.
