Joao Fonseca vs Yannick Hanfmann — R32 — Halle Open

World No. 59 Yannick Hanfmann flipped the ranking gap on its head at the Halle Open, holding the No. 25 Joao Fonseca to zero break points and 0% return games won across 16 games. The return pressure was the whole story — Hanfmann broke five times, including games 1 and 3 to open a 4-0 first-set hole, and won 88% on first serve to neutralize a Fonseca who came in off a quarterfinal in Paris. Fonseca's first-serve effectiveness cratered to 27% in the second set. Hanfmann books Alexander Zverev next.
