With no British interest in the men’s singles draw, following Andy Murray’s withdrawal due to a back injury, all eyes were on Robson at Roland Garros.
But the 19-year-old was beaten 6-3 6-2 in 71 minutes on Court Suzanne Lenglen and admitted to paying the price for making 39 unforced errors.
“I just made too many mistakes,” said the World No35. “I had a couple of break points that I didn’t take. If I had taken those, maybe it would have been a different match. After that I was just going for a bit too much.
“Generally I just wasn’t able to get into the match. My shots just weren’t firing as well as they usually are, so it’s disappointing.”
Elsewhere in the women’s singles draw, No2 seed Maria Sharapova made light work of Su-Wei Hsieh, triumphing 6-2 6-1, while China’s Na Li, seeded sixth, beat Anabel Medina 6-3 6-4.
Frenchman Gael Monfils claimed the biggest scalp of the day by defeating fifth seed Thomas Berdych in a five-set epic, 7-6 6-4 6-7 6-7 7-5, to thrill the home crowd.
On Court Philippe Chatrier, king of clay Rafael Nadal, who has been French Open champion seven times in the last eight years, recovered from losing his first set to Germany’s Daniel Brands to win 4-6 7-6 6-4 6-3.
Jo-Wilfried Tsonga and Richard Gasquet, seeded sixth and seventh respectively, made the most of home advantage to come through their first round matches against Alijaz Bedene and Sergiy Stakhovsky without dropping a set.
