I was worried by his reaction when he lost to Federer at AO. Seems to have knocked him a fair bit.
Me too - I think he believed it was his moment and that it was ordained somehow - his 17th slam, same as when Federer won his first - and having dropped only one set all tournament, plenty of time to rest and prepare for the final...totally different to the way the US Open unfolded, I think he thought "this time it's mine."
I think this reverse has been much harder to take because there's been no external factors he can blame it on at all - he simply didn't play well enough on the day.
I hope he can move past it quickly and learn the lessons he needs to learn and get back down to business.
I feel bad for him though, I hate to think of him beating himself up over it.
