Defending champion Coco Gauff digs deep in US Open to beat Svitolina

• No 3 seed defeats Ukrainian 3-6, 6-3, 6-3
• Plays compatriot Emma Navarro in last 16

Coco Gauff arrived in New York this month carrying significant unwanted baggage. Although her summer had not started badly at all, it had descended into disappointment with a slew of dispiriting losses in significant tournaments. In stark contrast to her circumstances last year, when she capped off the best run of her life with her first grand slam title, the American returned to the US Open still searching for her best.

In front of a rocking crowd in Arthur Ashe Stadium, Gauff took a positive step forward as she drew on her resilience and problem-solving abilities after a testing start, recovering from a set down to reach the fourth round with a strong 3-6, 6-3, 6-3 win over Elina Svitolina.
