From her facebook,she explains why she had to withdraw:
The tournament finished with the worst way..
yesterday it was a big day by winning singles and doubles! I was around 4 hours on court for the matches! My recovering was perfect..i did everything to be ready for today! This morning i was feeling really good physically and mentally! A bit more confidence with my game and my self!
I did the warm up before my singles match and i was feeling perfect and very happy to play! I was looking so forward for another BIG day!
I won the first set 6-4 and in the middle of the second set, at 3-3 i started to feel cramps in my left calf. After few games i felt the cramps to both legs...so it was impossible to keep playing. I had to retired from this match and also from the doubles. Very tough situation..very dissapoint it..
On top..all afternoon/evening..i don't feel good with the rest of the body.
I hope for a better day tomorrow! I will keep you posted!
