Britain's Sonay Kartal suffered a first-round defeat to Caroline Garcia at the Cincinnati Open.

The 23-year-old was beaten 7-5 4-6 3-6 by her French opponent, who won the 2022 tournament.

Garcia, the former world number four, will now face Karolina Muchova after the 31-year-old's first victory since 19 March, having announced in May, external she would retire later this year.

Kartal's loss followed first-round exits for fellow Britons Katie Boulter and Jacob Fearnley.

Boulter, 29, was beaten 6-0 7-5 by Serbia's Olga Danilovic, who will now face Emma Raducanu - who recently dethroned Boulter as British women's number one - in the second round.

Elsewhere, five-time Wimbledon champion Venus Williams went down to world number 42 Jessica Bouzas Maneiro.

The 45-year-old American received a wild card entry to Cincinnati after reaching the second round of the Citi Open in Washington last month, but was beaten 6-4 6-4 by her Spanish opponent.

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.
