Zurich, Oct 18: Belgian Justine Henin-Hardenne has pulled out of next week's WTA tournament in Linz due to exhaustion. The world number two, who won the tournament last year beating American Alexandra Stevenson in the final, would have been the top seed this time round. "Unfortunately, I have no option but to rest after this week to ensure that I will be 100-per cent for the WTA championships in three weeks' time," said the French and US Open winner. "It's going to take everything I have just to survive and get through this week in Zurich. Since the US Open I have been feeling more and more physically as well as mentally tired that it has got to the point where I must take a break from playing," he said. Bureau Report
