Errani losing does open up the draw, but the losses of Shvedova and Pavlyuchenkova do so just even more. I could have seen one of those two get through after Sara's loss.
It would be very nice to see Sveta get through and come back to a ranking which reflects her talent. Same with Caroline, who needs a good run here in other to start 2013 on a good note. Both of them in the r16s would be nice
