Emma Raducanu brushed aside Olga Danilovic at the Cincinnati Open to make a confident start with her new coach.
The British number one has added Rafael Nadal's former coach Francis Roig to her team on a full-time basis as she prepares for the upcoming US Open.
And the surprise 2021 champion in New York cruised to a 6-3 6-2 win in her first match since the Spaniard came aboard.
Danilovic beat British number three Katie Boulter in the first round while Raducanu had a bye, and the Serbian number one broke Raducanu to love in the first game of Saturday's match.
