Stefanos Tsitsipas vs Learner Tien — R16 — Geneva Open

Three hours and 25 minutes of clay-court attrition, and not one break of serve survived the breakers — Learner Tien took both sets 7-6, 7-6 over Stefanos Tsitsipas at the Gonet Geneva Open without ever leading by a set on the scoreboard until it was over. The margin was Tien's first-strike serve: 78% of first-serve points won to Tsitsipas's 63%, plus eight aces to three. Tsitsipas was the cleaner converter when he got a look — 2 of 4 break points to Tien's 2 of 7 — but he coughed up 36 unforced errors to Tien's 20, and that error gap, not the chances, decided two tiebreaks the American refused to lose in their first meeting.
