Valentin Vacherot vs Kamil Majchrzak — R64 — US Open

Down a set and broken back in game 4 for 2-2 in the third, Vacherot was living off one shot: a first serve he landed only 40 percent of the time and then won 81 percent of the points behind, 65 of 80 against Majchrzak's 64 percent, enough ballast to carry 12 double faults. The third-set tiebreak settled it. Majchrzak had gone stroke for stroke through that set, out-hitting the 22nd seed 17 winners to 15, and paid 17 unforced errors for the privilege; in the closing set he never earned a break point while Vacherot broke twice and missed just three balls unforced. Majchrzak saved one match point along the way, and Vacherot needed the next one, 3 hours 25 minutes in, to reach the third round of the US Open — the same player who arrived in New York off three straight losses.
