The latter I can't see not happening! Nishikori rarely beats Federer (H2H - 3 wins to Federer's 7) though he did beat him in their last match, though admiteddly Federer played really poorly. In the form he's in right now, it will take a small miracle for Nishikori to win.

As for Querrey, well he's got big fire power and is probably the more trickier of the two opponents on grass because of his serve and forehand. But getting past Nadal, again I can't see an upset in either match.

I covered Fed's chances of winning his tenth Wimbledon title in my first post here as I am really big tennis fan!

Who do you think would win out of Federer and Nadal then?
