Roman Safiullin vs Joao Fonseca — R32 — Wimbledon

Ranked exactly 100 spots below his opponent, Roman Safiullin flipped the match on return, breaking Joao Fonseca once in each set while saving all five break points he faced. Safiullin never yielded a break of his own — Fonseca went 0 for 5 on return — and the pressure told: the mid-set break in game 6 of the first, game 7 of the second, and a recovery after dropping serve early in the third. He won 77% of first-serve points to Fonseca's 61%, and after back-to-back five-set survival tests at Wimbledon, he needed only three here.
