Title is pretty self explanatory. Might include my own list a little bit later. These are players that have either shot up the rankings quickly and are on the way up, or players that have comeback this year and are on the right track again.
Hm, so Kerber improved much more than Aga?
Is that why she beat Aga in 2011 and lost twice 2012? Crazy thinking.
On my list: Radwanskas, Robson. Petrova, Hsieh, Errani, Kerber, Vinci, Watson, Ormaechea
