This match (and championship) is Nadal's to lose.
I suspect he'll break Federer again on the next serve to win this set, too.
On a side note, does anyone else find it annoying when the Wimbledon crowd choose a favourite when they have no reason to? It's not like a Brit is playing, but (like last year) they're clearly all favouring Nadal.
Which annoys me, because I don't like him.
