I was thinking about this a few days ago
Player of the Year:
Very hard to say, but probably Na Li or Petra Kvitova, depending who ends the year ranked higher. Possibly Serena Williams though if she can win the US Open and YEC, although they will probably be hesitant since she only played for half the year. However, should Caroline Wozniacki or Maria Sharapova win the US Open and/or YEC, then one of them would probably take it.
Doubles Team of the Year:
Most likely Kveta Peschke/Katarina Srebotnik.
Most Improved Player:
Very tight between Petra Kvitova and Na Li. Maybe whichever ends ranked higher? Or maybe if one gets POY then the other will get this...
Newcomer of the Year:
No obvious choice at all! Should Irina Begu, Ksenia Pervak, Christina McHale, or Bojana Jovanovski win a title it would probably be one of them. Otherwise, probably Begu for reaching two finals, although I think Bojo could take it, as she has the bigger game.
Comeback Player of the Year:
I never know for this one
maybe Liezel Huber for organizing the hair donation though?
Karan Krantscke Sportsmanship Award:
Kim Clijsters, most likely.
Maybe Caroline Wozniacki, as she seems tireless. Doesn't this have rankings though?
Humanitarian of the Year:
Hard to say... Liezel Huber maybe
