Coco Gauff felt like she was the Golden State Warriors in Game 7 of the NBA Finals when she heard her named chanted by the Louis Armstrong crowd in Thursday's US Open second-round win over Timea Babos. Teenage sensation Gauff was again responsible for a thrilling contest at Flushing Meadows, where the 15-year-old American outlasted Babos 6-2 4-6 6-4. Gauff prevailed after a frenetic two hours, 23 minutes, during which the vociferous crowd frequently led 'Coco' chants as she set up a clash with defending champion and world number one Naomi Osaka.
