Britain's Harriet Dart narrowly avoided a dreaded double-bagel for the second time at a grand slam, losing 6-0 6-2 to Italy's Martina Trevisan in the first round of the French Open.
The 25-year-old from London failed to win a game in a first-round defeat by Maria Sharapova at the Australian Open in 2019.
Dart must have feared a repeat at 6-0 3-0 down, but she at least managed to get a couple of games on the board and can console herself with almost £53,000 in prize money for her hour and 25 minutes' work.

Rafael Nadal began his bid for a 14th Roland Garros title with a straight-sets victory.

Raducanu went on to comfortably take the final set and complete a 6-7 (4) 7-5 6-1 victory.
