Jannik Sinner vs Miomir Kecmanovic — R128 — Wimbledon

Down a set after dropping serve twice in the closing two games of the opener, Jannik Sinner found the return edge that decided this one — converting 4 of 9 break points to Miomir Kecmanovic's 1 of 4. The match flipped for good in the fourth set: after a third-set tiebreak slipped away 7-6(6), Sinner broke in games six and eight and held Kecmanovic to 56% on first-serve points won. Thirty aces to one and a 71-to-20 winners count carried the back half, the Wimbledon top seed surviving an opening-round scare across five sets.
