Instead of berating Andy you should be saying well done for doing what great players do and that is turning a match round and then going on to win easily. Andy said in his press conference that he doesn't play well on Armstrong. Once it got darker and the conditions slowed down he was able to play well. Be ready to cheer him on to victory against Berdy on the AA court which Andy loves playing on.
I agree we should focus on the positive of Andy turning it round in what sounds like pretty spectacular form or at least causing Cilic to crumble completely in final set. I guess one thing Andy and Lendl need to think about is how to cope when he has to play on courts he doesn't like. But it must have been really difficult as he wouldn't have had time to prepare for that whereas I guess Cilic has played more on LA so far. I thought Andy didn't look too happy trudging over to LA at the start. But brilliant in the end and that is his 7th GS SF out of last 8 - what a record.
I think another factor might have been the empty stadium when they started. After a night match on Ash that must be something of a psychological come down. Jonathan Ovarend suggests that was a factor too:
"It must have been odd for Murray to go from a full house New York night session to the feel of a behind-closed-doors match.
"Things were flat as a Manhattan pancake when the match started - switched to Louis Armstrong in front of a hardcore few - and Murray's lethargic play wasn't helping.
"But as the Roddick match ended, crowds started to file in and Murray responded, feeding off the extra energy. Crucially, he also started moving his feet and putting pressure on Cilic with deeper groundstrokes.
"The Croatian got tight, spectacularly so when leading 5-1 second set, and the moment Murray levelled the match - impressively from 4-2 down in the tie break - there was only going to be one winner."
