Emma Raducanu says she is "learning to be effective" on clay as she makes the final preparations for her senior debut at the French Open on Monday.
The British number one, 19, starts the clay-court Grand Slam with a first-round match against Czech qualifier Linda Noskova at about 15:00 BST.
Raducanu, seeded 12th, follows British men's number one Cameron Norrie onto Court Simonne Mathieu in Paris.
Fresh from winning an ATP title in Lyon on Saturday, 10th seed Norrie faces French wildcard Manuel Guinard in his opening match.
Raducanu and Norrie are among the five British players in action, with 29th seed Dan Evans, Heather Watson and Harriet Dart also starting their campaigns.
