Terence Atmane vs Jakub Mensik — R32 — Canadian Open

Serve integrity decided it. Mensik never lost a service game across 11 of them and faced exactly one break point all evening, while Terence Atmane fired 11 aces to three and still coughed up two of the ten break points he faced, having converted none of his own. The 13th seed prised the opener open with back-to-back breaks, the second in game 12 for 7-5, then took the only one he needed in game 9 for 5-4, closing in 1 hour, 40 minutes with 38 of 43 first-serve points banked. Next up at the Canadian Open: Botic Van De Zandschulp, No. 69.
