It's a total frustration for me to see Nadal lost the battle in today's quarterfinal.
He is not fully fit for this Grand Slam tournament and fighting Fernando Gonzalez, who beat Hewitt and James Blake in the 3rd and 4th rounds respectively, was a tough one.
Anyway Gonzalez has done a good job with his groundstrokes. It's amazing to see him played so well on the hard court considered that he is a clay specialist. He had a good year last year. And in 2007, I think all of us might want to watch out for this guy.
