Aleksandar Vukic vs Daniel Altmaier — R128 — Canadian Open

Break-point conversion, not volume, decided it. Daniel Altmaier took 4 of his 8 chances while Aleksandar Vukic converted 3 of 12, including 1 of 6 in a second set the qualifier opened with a break for 1-0. A set down after the opening tiebreak, Altmaier answered in game 8 for 4-4 and squared the match in another breaker. The third flipped three times in five games. The No. 62's break in game 5 for 3-2 held, while Vukic, 74 percent on first-serve points and winner of their lone prior meeting on record at Wimbledon in 2023, still finished five points light overall. Altmaier closed it out in 2 hours, 58 minutes at the Canadian Open and would go on to face then-No. 33 Brandon Nakashima.
