I heard you didn't see the box so yes, Sargsian was there to coach him. With his father, Novotny and Karlis.
What else can I say you don't know yet... It was just a really bad performance. Very passive, all Kavcic had to do was hit back and let Ernie make the error. Not that I'm underestimating Kavcic' effort, he really kept fighting to get to every ball - but Ernests is ought to do better than that.
As I tweeted, he was in a very good mood at practice. Asking Karlis to keep serving so he could return, even when half of the WTA was on court waiting for him to get off
So maybe he took it too lightly, he was too relaxed, he does indeed have a virus and feels tired because of it, I don't know and I don't know when we will. So from that point on, the only way to go is forward. On to the next...
