I don't think the crowd had anything to do with the result. Recall in Paris against Gasquet when he was loudly booed even when walking onto the court. He couldn't stop grinning! And at the end when he won and was being roundly booed again he was grinning like a Cheshire Cat that had got all the cream. Water off a duck's back. He is tough enough to handle it.
I agree BN, that Andy is tough enough to handle what happened last night. He won't blame it for the loss, and he won't dwell on it, but I don't think that is the point.
It's interesting that you mention the FO. I watched the Gasquet match too, and Andy clearly enjoyed being cast as the villain in the eyes of the French crowd. However, I do think there is a difference. The crowds at Rolland Garros are basically a panto crowd. They cheer who they want, they boo who they want, they've even been known to switch sides halfway through a match. Sometimes you'd half expect a Rolland Garros crowd to yell out 'He's behind you!', or whatever that is in French.
At the FO there is a sense that 90% of what the crowd does is for fun, things like booing a player for challenging a call, that sort of thing. Rarely, if ever, does it feel like there is much venom in what they do. Last night was not remotely the same sort of atmosphere. Right from the start, in what even Petch called an 'electric' atmosphere, when he was analysing the various tactics that might be employed, the atmosphere was ugly. Rather than a Sunday evening, it was like a rowdy Saturday night at a grotty pub in a low part of town.
It was as if the crowd was baying for Andy's blood, literally. Some of it, I'm sure, was fuelled by over indulgence in the bars in the arena, but that is no justification. Even when Andy was ahead in the first set it was uncomfortable viewing. The crowd clearly had one winner in mind, and it wasn't the man who was in front at that point. Then came some errors from Andy. Any decent tennis fan knows you do not cheer double faults, but that is what they did, in fact they went further. I really do think they were trying to intimidate Andy off the court.
In a way I was glad when it was over and Andy got off the court quickly, but again, for no reason, he was booed. I'm not even sure the crowd reaction would have been any different if he'd won. I suspect it could have been even worse. I am not a dramatic person by nature, but I must admit to having feared for Andy's safety last night. It was one of the most awful situations I can ever remember seeing in sport. Andy, at the very least, is owed an apology.
