Berlocq ran a little bit out of gas but played great and was admirable : some of his backhands and volleys were great
Nadal decided to fight as well in the end, which is nice. Not sure the final will be as tough.
I wonder what would have happened if the umpire hadn't overruled Berlocq's serve on gamepoint at 3*-2.
Overall I think he was a little bit unlucky and deserved better.
