Tallon Griekspoor defeated Alexander Zverev 6(3)-7(7), 6-2, 6-4 — Canadian Open 2026 R64.
Alexander Zverev and Tallon Griekspoor: Alexander Zverev leads 7–2 across 9 recorded meetings.
Break-point arithmetic decided it. Tallon Griekspoor pried open nine break chances to Alexander Zverev's one and cashed four, flipping a match the betting market had priced 83 percent toward the top seed. After dropping the opening tiebreak, the ATP No. 67 broke three times in the second set, and when Zverev broke for 4-4 in game 8 of the third, Griekspoor broke straight back in game 9 for 5-4 and served out the upset in 2 hours, 34 minutes. He had come in 1-7 on record against the ATP No. 2 — the lone win, at Indian Wells last year, also came from a set down — and the Canadian Open loses its No. 1 seed before the Round of 32.
