Tallon Griekspoor vs Matteo Arnaldi — R32 — Canadian Open

The net decided it. Griekspoor took 15 of his 18 forecourt points to Arnaldi's 3 of 8, and though the Italian was the tidier returner at four break points converted from five, the Dutchman manufactured nine and cashed five. Arnaldi hit 26 winners to 19 and 10 aces to four, credentials the betting market had already discounted in installing the ATP No. 67 as a 65 percent favorite over the No. 30 seed. The break in game 5 for 4-1 gave the third set its shape. Arnaldi saved two match points before Griekspoor broke in game 9 to close it, 2 hours 12 minutes in, evening the meetings on record two days after he ousted Zverev. Daniel Merida Aguilar, No. 61, is next.
