Yes I noticed that too - it was when Andy was playing very passively so perhaps he was telling him to hit through the ball? Interesting, not seen Lendl do that before on court.
Oh good. I thought I might stand accused of being negative, but not once have I seen Lendl change even his facial expression during a match. As I recall, he had his hand on the edge of the box and raised it briefly. Telekinesis or not I think we were all going a bit mental at that stage! Whether Andy's passiveness was due to nerves or the fact that his feet were slipping around in his shoes (which he changed at the break) goodness knows, but I hope Aggressive Andy shows up against Cilic, otherwise he'll probably lose.
I also hope, if he must keep a ball in his pocket, that he has a word with Adidas on the matter so's they can give him deeper pockets.
I think I've only seen that happen once to a player, never mind 3 times in one match - and those two lost points could have been very costly indeed.
