Have to say that Murray was excellent today, was playing the way he can when on top form. Federer just never looked like turning the tide the way he did a month ago and everything seemed to fall perfectly into place for Murray today; number of unforced errors on Fed's part, shots he would normally over hit played to perfection on the line, etc.
I think this could be the catalyst for him to finally get a grand slam. The confidence it will give him and psychological edge knowing himself that he can do it now, he has won something really big. Also, the fact it came at the expense of Federer less than a month after he lost to him on the same court will be huge. People might say that winning this wouldn't be as big an achievement as winning Wimbledon for a tennis player and that Fed might not have cared as much about it, but I disagree because you get a lot more chances to win Wimbledon than you do an Olympic gold medal.
I think he might just get a grand slam within the next 12 months, my bet would be the US open.
