"I didn't move my best tonight, but it didn't feel like I was moving really badly," said Murray, who was playing his first match since reaching the Dubai final. "My return let me down, and he hardly missed the ball, either. That's the thing. The level of tennis nowadays you get no easy first round matches and you play poor match, that's what happens. So can't allow it to happen. I don't know exactly why because I was playing really, really good tennis the whole of the week and the buildup to it."
Sometimes, sh*t just happens.
I'll be watching livescores for the doubles but I'll be back for Miami 
I haven't watched the match yet or read
all of the postings re the match. However, having read some I totally agree with Bevc. This time last year we were all shouting for Andy to get a coach - he has, and as far as I can see his game
is changing due to Lendel's input. A BBC report I read first thing this morning suggested that his backhand went awol - I've noticed this in many of his matches since Ivan has been taken on board. Obviously, the tactic atm is to be more aggressive/improve the first and second serve and his forehand (which he has) it's becoming a huge weapon - but maybe to the initial detriment of what was an amazing backhand. The match stats suggest that he was having a particularly bad day (again) and that G-Lopez was on his game. That's all!
It's not Jet-lag, it's not psychological (thank God) it was just a bad night. I'm sure the Murray team will be fully analysing what went on and working on those aspects in the next ten days. Roll on Miami - and let's all just hope this is yet another blip and also that more lessons will have been learned.
