Re: Strengths and Weaknesses of Top 10
OP and Griffin both made great lists, I'd like to add few things.
1. I don't think that Serena lets opponents get inside her head, my impression is that sometimes some bad misses get inside her head (rather than opponents) which was mostly visible in the first part of the season when she simply couldn't win ugly.
2. I don't think that Sharapova is the strongest mentally, Vika and Serena are stronger mentally.
3. Errani's return and mental fortitude are seriously underrated. I'd like to add it to list of her strengths.
4. Azarenka has a great touch, good volleys and drop shots.
