Didn't Federer break back when Nadal served for the match in that RG final 2006 ??? A strange way to give up IMO. It's hilarious how little confidence a lot of Federer fans have in their "hero".
So it's just a break. Roger can learn a lot of Steffi in the mental department. She lost to Sabatini 5 times in a row in the US, but never walked on the court with a beaten look. And after that Sabatini never beat her again. BTW Í am fan, he is not my hero, Graf is.
