I didn't think Delpo had to do much to win that, particularly in the last set - Fed really was not at his best. I agree with TJ about the crowd - they were about as partisan as you could get - understandable but very unsporting. I never normally want Fed to win but today I did only because I don't want Delpo getting ideas above his station and coming into the WTA brimming with confidence.
I don't think Delpo would mind playing in the WTA.
I think he has a right to be confident ,, although that Serena can be a bit scary.
