Joao Fonseca defeated Casper Ruud 7(8)-6(6), 6-3 in the R32 of the Canadian Open 2026.
Break points decided it. Fonseca converted two of three and saved six of the seven he faced, while Ruud, the No. 9 seed, went 1 for 7 on return with seven double faults to the Brazilian's two. The opener swung twice inside two games — Ruud broke in game 6 for 4-2, Fonseca broke back in game 7 for 3-4 — and two set points came and went before the tiebreak settled it; the market had made the 19-year-old a 56 percent favorite regardless of the ranking gap. Ruud saved a match point before the end, 1 hour 54 minutes in. Fonseca, 2-0 against him on record since their French Open meeting, still hasn't dropped a set this week and moves on to Ben Shelton (No. 8).
Casper Ruud: 3 aces, 24 winners, 57% first serves, 7 double faults, 1/7 break points. Joao Fonseca: 5 aces, 35 winners, 64% first serves, 2 double faults, 2/3 break points.
