Federer was in a realm of his own and after he saved another three break points in the third game of the second set, the match was over as a contest and became almost an exhibition of the 25-year-old's extraordinary skills.
An exquisite running backhand found the corner to help him to a sixth break for 5-3 in the third but Blake restored some pride by breaking when Federer was serving for the match.
"It's quite incredible to finish off by winning the Masters Cup, the world championship so to speak," said Federer. "It's obviously a perfect end to an incredible season.
"I had to laugh at one stage I was playing so well, everything I tried today worked."
