Anyone else find it interesting that Nadal is often portrayed as this warrior who would die before losing a tennis match, even though statistically Federer is the greater fighter. 27 times in his career, Federer has lost the first sets of a Grand Slam match. 7 times or 26% of the time he has fought and come back to win. 15 times in his career, Nadal has lost the first two sets of a Grand Slam match. 2 times or 13% of the time he has fought and come back to win.
