3. US Open 2005
vs Andre Agassi
Federer kept up his 100 percent record in Grand Slam finals to pick up his sixth title and second straight Flushing Meadows trophy with a four set win over tennis legend Andre Agassi which ended 6-3 2-6 7-6 6-1
It turned out to be the losing American's last appearance at a Grand Slam final. The 35-year-old drew level in the second set but he wasn't able to overcome his younger opponent for a third and final US Open win.
Federer described the 2005 win as one of his most special considering the circumstances and opponent.
The top seed and world no.1 also beat former US Open champion Lleyton Hewitt and David Nalbandian that year.
That 2005 win was part of five consecutive wins in New York, although he hasn't won the title since that streak ended in 2009.
