The second seed Kim Clijsters is out of the French Tennis Open after her worst performance in Paris in more than a decade.
The current Australian and US Open champion, who had been in some doubt for the tournament because of an ankle injury, won the first set but lost in three to the Dutchwoman Arantxa Rus - who eliminated New Zealand's Marina Erakovic in the opening round.
Clijsters blamed her attitude for the loss, saying she started doubting her game after playing a great first set, and was guilty of 53 unforced errors and nine double faults.
The women's seventh seed and former world number one Maria Sharapova avoided an even greater embarrassment by coming from a set and 1-4 down to beat the French 17-year-old Caroline Garcia to go through to the last 32.
In the men's draw Rafael Nadal was made to struggle by fellow Spaniard Pablo Andujar, the defending champion recovering from 1-5 down to take the match in a tiebreaker third set.
And the fourth seed Andy Murray beat the Italian outsider Simone Bolelli 7-6 6-4 7-5.
