Quite frankly Kaia was beating herself throughout most of the match. Aga's job was being solid and waiting for the error. In the 2nd set, it started to look interesting. Finally Aga showed some skills. Good luck in the QFs!
she is very tired but late withdrawing from Linz would cost her much $$$
Tired? Tired of what? Of being #10? In recent months she played a small fraction of what she used to play before. Some people who don't know her think that a player must be grinning all the time. Failing to do that they take to be a sign of not 'enjoying the game'. There is a third option they should consider: she may just be focused on the game.
