I think that guy Ravi Ubha put this list together. I only see his name in the article. It has the men too and I'm assuming it's based on hard court play leading up to the Open given that Mardy Fish is the 2nd rated man. But we all know Mardy AINT beating Nadal or Murray at the US Open. COME ON SON!!!
It's a good list. Petko is an odd choice but the rest are pretty accurate reflecting their form on hard courts.
Serena and Maria deserve top 2 mentions and we all know why Caro is at the bottom. Na, Sam and Aga all had pretty good lead-up tournaments. Just because they didn't win titles doesn't mean they are "slumping". All they need are a couple of solid performances and wins.
You have really always been a terribly annoying and immature poster, particularly given your handle.
ETA: Apologies to everyone else; I've been meaning to put this sour poster on ignore for a while. I shouldn't have let it get personal, which is why I have half the board on ignore. Let's get back on topic.
