Britain's Harriet Dart says she is enjoying having her mum as her coach as she prepares for her second-round US Open match against Marta Kostyuk on Wednesday.
The 28-year-old sailed though the first round with an assured 6-1 6-2 win over Chloe Paquet of France.
She will now face Ukrainian 19th seed Kostyuk as she bids to reach the third round at Flushing Meadows for the first time.
Dart's mother Susie has stepped up as her coach for the New York tournament because her regular coach Olga Morozova is reluctant to travel outside the UK.
