A final often finishes with contrasting images, ones that never quite fade. The winner, euphoric after the last point, lying on her back and looking up at the New York sky, like Iga Swiatek on Saturday. Ons Jabeur, fighting back her emotions as the Pole wrapped her in a hug. The Tunisian’s box, sporting her ‘Yalla Habibi’ tees, make a desperate attempt at control. The triumph and the tears of an evening in Flushing Meadows.
