Playing three matches in three days seemed to take its toll on Sania Mirzas body on Tuesday as her Dubai Open campaign ended in the second round with a 7-5 6-2 loss to world No 24 Kaia Kanepi of Estonia.
Just the previous day,Sania,who is still recovering after an injury-marred 2008,had beaten Russias Ekaterina Marakova in the first round in Dubai.
The Indian and her Italian partner Mara Santangelo were due to play a doubles match as well,but made it through to the second round after their first-round opponents gave a walkover.
In her second round singles match,Sania let slip a 4-2 lead in the opening set and couldnt manage to recover after being broken in the eighth game. Both players fought hard in an intense battle,but eventually,the Estonian managed to pull off the win.
Second seed Dinara Safina slumped out in the second round on Tuesday after losing 6-4 6-2 to Virginie Razzano of France.
Sixth seed Venus Williams was in magnificent form as she brushed aside Russian teenager Anastasia Pavlyuchenkova 6-0 6-1 while third seed Jelena Jankovic defeated Romanias Monica Niculescu 6-3 6-2.
Russian Safina had reached the final of both tournaments she has played this year,first in Sydney and then at the Australian Open. But she looked completely out of touch against Razzano,who was aggressive but often had to do little more than wait for Safina to lose the point.
Serbias Jankovic found her opponent Niculescu difficult to adapt to,as she kept her guessing what shot she would produce.
Fifth seed Vera Zvonareva dominated fellow Russian Vera Dushevina 6-0 6-3,10th seeded Alize Cornet of France crushed German qualifier Julia Schruff 6-1 6-2,and 11th seeded Marion Bartoli of France defeated Francesca Schiavone 7-6 3-6 6-3.
