Ana Ivanovic smiling again in US Open 2011

It is definitely good to see Ana Ivanovic smiling again, after putting together a string of decently played matches at this year's US Open. Of course, she certainly doesn't look like going all the way but at least she's winning against the opposition below her in ranking which until recently wasn't the case. And more importantly she's smiling again. Oh, that lovely smile of hers.
