Patrick Kypson vs Stefanos Tsitsipas — R128 — Madrid Open

Stefanos Tsitsipas flipped this one in the breakers after Patrick Kypson grabbed the first set 6-3, holding off match-long pressure to win 3-6, 7-6(6), 7-6(7) in their first meeting. Kypson actually won the second-serve battle 64% to 44% and committed zero double faults to Tsitsipas's three, but the Greek's first delivery carried him — 86% of first-serve points won to 55/71 (77%) — and his 14 aces edged Kypson's 11. The error ledger nearly cost him (42 unforced to 23), yet 46 winners against Kypson's 28 made the difference across two tiebreaks.
