Coco Gauff survived a shaky serving performance to battle past Ajla Tomljanović in the first round of the US Open, winning 6-4, 6-7 (2), 7-5 after 2hr 57min on Tuesday night.
The No 3 seed finished with 10 double faults, was broken six times and squandered a string of opportunities to close the contest earlier, but conjured enough resilience to scrape into round two under the lights on Arthur Ashe Stadium.
