Alexandra needs to take some time off.
Come back in 5 months play some WTT and if you are playing better than you are now maybe beg USTA for a wild card again at US Open. Maybe with some nice results in WTT they might give her one.
Alex has been having some pretty rough draws in her defense. She got Arvidson in Memphis last week, who went on the whole thing, and Salerni is coming off winning a 75K in Midland this month. Even when she played 25K Qualies, she drew the top seed in Eva Fislova, who was ranked considerably higher than the other seeds.
At the same time though, if Alex is planning to make it back to the top 100 she HAS to be winning matches like these (maybe not Sofia, but every one else).
She needs to suck it up, go to Europe or Asia, and play 10K's. It's as simple as that.
