Elena Baltacha's hopes of progress in the ITF Challenger in Athens have been hit by a bout of food poisoning.

The Scottish number one won a tough first round battle with Uzbekistan's Akgul Amanmuradova 3-6 7-5 7-6, winning the final set 7-4 on the tie-break.

She was due to face Petra Kvitova (Czech Republic) in the next round but was forced to withdraw from the tournament due to illness.

It is a setback for the player who recently made the world top 100 but she is expected to be back playing within the next few days.
