I was referring to Papa actually and you did not sound bitter.
Sorry about that, misunderstood who the question was referring to. And yes I have seen him play, but not for the whole match (saw a set against Jared Hiltzik). I also followed his match on the radio before. He is an aggressive baseliner with good serve and size, thus the reason why I favor him over the other Americans that I saw.
And no, I don’t know him personally or that well; but I follow his results, and other American juniors', closely. So I got an idea of what his strengths and weaknesses are. Most of his results came on slow outdoor and clay. He is horrible on fast surface, especially indoor (most of those losses were along the line of 6-3 6-1, 6-2 6-1 scores
I didn’t mean to make it sound like he is head and shoulder above Di Feo. They are completely two different types of players and I thought that with his gamestyle he would have the advantage. Maybe it was wrong of me to make an assumption like that, but I doubt that Papa would get destroyed that badly if it was outdoor and based on past history.
