number four Stan Wawrinka was forced to withdraw from the Metz ATP event on Friday
with an ankle injury, handing Philipp Kohlschreiber a semi-final spot.

"Unfortunately, I have to pull out
because yesterday I twisted my ankle at 5-4 in the first set," said Swiss
"It was painful in the match, but
still OK with tape on it. But after a lot of treatment last night and some
tests this morning, it's dangerous for me to play because the pain is still
there. So I will have to see a doctor to see if I will be OK in the next few
