If murray can reproduce that performance in other slam finals he will win one.
It was a close match, he had break points against federer in every set. Infact the second set he looked on top and was unlucky not to get at least a tie break. That 10 deuce game in set 3 was also of importance, again federer just managed to triumph but it was close.
The rain break helped federer aswell, as he was the older player, getting 30-40 minuntes rest at what turned out to be about halfway through the match would have helped him.
