Well atleast he played a really good match and will go in with some confidence. Seems like the domination from the top4 is only getting worse..
It's been like this at the AO for a few years, I think, even for Murray.
I've always thought the moderation of the surface had something to do with it, but if the courts have sped up as reported then I'm not sure.
In any case, the earlier rounds at the other majors have typically been more competitive, I think.
