Federer's triumph here at London's 02 Arena 12 months ago moved him level with Pete Sampras and Ivan Lendl on five titles in the end of season finale.
The 30-year-old, down to fourth in the world rankings, will finish the year without a Grand Slam title for the first time since 2002, but he arrived for 2011's concluding tournament in good form after back to back titles in Basel and Paris.
Federer said: "Jo-Wilfried served well in the second set and it was hard to control the rallies at the baseline.
But, I think this is the best I've played all year. It helped that I had some good time off before playing great at Basel and Paris."
