Cameron Norrie and Harriet Dart both fell to first-round defeats at the French Open, with British singles players yet to register a victory in Paris.
British number one Norrie has never made it past the third round at Roland Garros and he fell at the first hurdle this time, the 32nd seed beaten 4-6 6-3 3-6 7-6 6-2 by Pavel Kotov in four hours and 13 minutes.
