Karen Khachanov vs Marco Trungelliti — R64 — French Open

Three hours, 38 minutes of attrition, and the difference was the serve that never cracked: Khachanov hit zero double faults to Trungelliti's eight, and won 72% of his first-serve points to the Argentine's 62%. Trungelliti pushed back after dropping the opener in a tiebreak, taking the second 7-5, but Khachanov flattened him 6-1 in the third and converted six of 12 break points across the match. The fourth went to another breaker, where Khachanov closed it 7-4 — winning both tiebreaks in their first career meeting, and first on clay. Ten aces to five, and the cleaner ledger held up when the legs didn't.
