British number one Emma Raducanu has split with the coach who guided her to a first major title at the US Open.

Andrew Richardson was hired for the summer tournaments in the United States, which ended with the 18-year-old’s improbable victory in New York.

Raducanu had entered the tournament as a qualifier, and the world number 150.

The new British number one says she has no prospective coach in mind, and would like to do some trials once the season is over.

Her thoughts are now turning to the remainder of this season, and she is likely to decide over the weekend whether to play in next month’s prestigious BNP Paribas Open at Indian Wells, California.
