Valentin Vacherot vs Mariano Navone — R64 — Canadian Open

Break points on return decided an otherwise level Canadian Open meeting, and they ran against the market, which had Valentin Vacherot at 61 percent. Mariano Navone converted 4 of 7 chances to the No. 14 seed's 3 of 7, while Vacherot's first-serve points won slid from 87 percent — five aces — in a 6-1 opener to 52 in the decider. The ATP No. 18 had taken their only prior meeting on record, at Miami in March, but the rematch turned on Navone's break in game 7 of the third for 4-3. He broke again in game 9 to finish it, converting a second match point after Vacherot saved the first, 2 hours and 3 minutes in.
