Apparently Bartoli has a right shoulder problem at the moment, hence her large number of DFs, as a result she has additional focus on the strongest part of her game , her return.
If you're trying to draw a positive on Laura's serve, she managed to get 80% of her second serves into court compared with only 73% against Radwanska, progress.
There hasn't been much doubt in my ind for a month or so now that once Laura sorts out her sorve (or should I say if), she'll get top 30 pretty quickly if not top 10.
