For anyone who doubts whether Nadal was injured, just look at his first serve @ 6:34
. Are you frigging kidding me??? Yet still , all this ridiculous banter on here persists, it is embarrassing. As far as the commentators are concerned, they are just doing their job. Nadal stays, they stay. They are not going to sit there and say "Oooh…did you see that shitty serve? He should quit!" Were it not a final with a gazzllion people watching,even Nadal would have considered throwing in the towel at this point, but he stayed, and did what he could. As far as Stan, he is a great player, and it's not easy to play against an injured opponent, especially one the likes of Nadal in a Slam final. Hence dropping the 4th set. It's that simple.
