Former world No. 1 Kim Clijsters is set to make her comeback from a five-month injury layoff Wednesday after receiving a first round bye in the tournament, which is being held near her hometown in eastern Belgium.
Clijsters is seeded second behind US Open finalist Elena Dementieva of Russia, who also starts on Wednesday. Clijsters will face Benesova, while Dementieva takes on Pastikova.
Clijsters has been off the circuit since May when a wrist injury forced her to withdraw from the German Open in Berlin. She needed surgery to repair a torn tendon and failed to be fit in time for the US Open.
