The amazing numbers don't stop there. Federer has appeared in 19 out of 24 Grand Slam Finals since his first appearance at one at Wimbledon in 2003. He hasn't lost a Grand Slam Final to anyone other then Rafael Nadal, against whom he has last 5 times. Federer has also not lost to anyone other than Nadal at the French Open (where his performance in Grand Slams has been the weakest) in the last 4 editions of the tournament. This was Federer's 4th straight Grand Slam Final. The irony is, that in the last 15 months of so, Federer has more or less consistently been second best to Nadal.
If it hadn't been for Nadal, Federer would have been professional tennis's equivalent on Bradman! As it is, in mens tennis today, there's Nadal, Federer, daylight, and then the rest.
Roger Federer is 27 years old.
