Is Nadals dominance at the French Open the most dominating performance in sports history?

Last month Rafael Nadal captured his 11th French Open title in 13 tries.  His overall match record at the event is an astounding 86-2, a 97.7% win rate.  Since he first competed in the event in 2005 he has only dropped a total of 25 sets in his 13 years of competing at the event.  That is less than 2 sets per year.  He has also won the tournament 3 times without dropping a single set throughout the entire tournament.

For an apples to apples comparison we will look at Roger Federers record at Wimbledon.  He has won the event 8 times in 19 tries, the most wins at a single event other than Nadals 11 at the French Open.  His record at Wimbledon is 91-11 a win rate of 89.2%.  He has won the event once without dropping a set throughout the entire tournament, which he accomplished just last year.  Federer has dropped a total of 61 sets through his 19 years of competing at Wimbledon, which is just over 3 per year.  Very very dominant, but not quite as dominant as Nadal at Roland Garros.

Are there any other sports superstars who dominate a single event like Nadal?  Let me know in the comments below.
