I read on the WTA site that Maria won in today's quarter-finals, against Angelique Kerber from Germany, due to an injury of her opponent (the score was in favor of Maria by 60 30). It isn't the case to celebrate when the opponent suffered an injury. Console ourselves with the fact that Maria is in the semis. Maria will face Li Na from China, a very tough player.
"In bocca al lupo", Maria! 
Take care of yourself. Giorgio from Italy
