Amelie Mauresmo suffered her second embarrassing defeat in two weeks after she was humbled 6-2, 6-0 by Slovenian qualifier Katarina Srebotnik at the Zurich Open.
The French second seed was overwhelmed by an opponent who had not claimed a set from Mauresmo in their previous three meetings.
Last week in Moscow, Mauresmo was beaten 6-1, 6-1 in her opening match by Francesca Schiavone.
Mauresmo began with an ace but lost her way very quickly and surrendered her opening service game with a forehand error.
Looking flat, she allowed 43rd-ranked Srebotnik to dictate play.
A backhand volley gave her a second break for 4-1 and she closed out the first set with an easy forehand winner.
With Mauresmo continuing to struggle in the second set, Srebotnik romped to a commanding 3-0 lead before she completed the one-sided win.
