West Australian Casey Dellacqua threatened to post the first upset of the French Open on Sunday before eventually going down in the opening round.
Dellacqua, a former women’s doubles finalist at Roland Garros and the reigning mixed doubles champion, led 21st seed Sara Errani by a set and a break on court three.
But she let the big opportunity slip, dropping 11 of the next 13 games to lose 4-6 6-2 6-2.
Errani came into the tournament boasting a tour-best three titles on clay this season.
Three Australian men open their campaigns on Monday, hoping to join Australia’s sole winner on Sunday, Sam Stosur, in the second round.
Bernard Tomic, the 25th seed, plays Austrian Andreas Haider-Maurer, Lleyton Hewitt takes on Slovenian Blaz Kavcic, and Matthew Ebden faces German 24th seed Philipp Kohlschreiber.
