Amazing match. Shame one of them had to lose, but that's tennis.
Both served great, played great and fought their heart out for their nation out there, but only one could prevail. Amazing stuff.
Del Potro played out of his skin on his worst surface against the 7-time champion, but Federer served too well in the end. Hope he doesn't get discouraged, he's on the right path to return where he belongs: in the mix to win big tournaments. Still, must be such a gutting defeat for him and his fans of course
