Watched the replay on ES HD. Some shotmaking were great (27 rally, like playing table tennis!) and some points would have finished earlier if Petra hasn't improved her movement. Last game was just sad, Li sort of gave up on RoS after that replay point.
NaNa - good fight on your last service game.
Keep your ambition for another GS and top 3 debut. It'd be great to see a first 31+ top 3 debutante (surely that's some record for WTA + first Asian top 3 single player).
Petra - good to have you back, keep your good work!
No same group for these two at YEC please.
